CureGPT
Everyone's chattering these days about how AI will save or destroy humankind. Setting aside the hype and the noise, how can AI empower families and foundations battling ultra-rare genetic diseases?
Everyone with Internet access has either heard about or personally tried ChatGPT at this point. Neural networks, so last decade. Large language models — LLMs to the illuminati — are so hot right. Prompt is on its way to becoming Word of the Year.
Founders and other early adopters are about to be 10X’ed. That includes parent founders racing to save their kiddos battling ultra-rare genetic diseases. What are some practical AI suggestions for parent founders like Jill Hawkins, founder of FAM177A1 Research Foundation, who are trying to stretch the value and impact of the precious dollars they raise?
For starters, Perlara wrote a CureMap for FAM177A1 but soon GPT-4 (or it successor GPT-5) will be able to generate the first draft of a CureMap for any gene in the blink of an eye. We meatbags will be brought in for what the cognoscenti call RLHF — Reinforcement Learning from Human Feedback. Humans are still needed to establish ground truth, which means fact-checking citations, removing hallucinations, and editing the first draft of personalized medicine into a finished product.
Thing is there won’t ever be a truly finished product. AI will one day continuously refresh and automatically update your CureMap on the fly, ingesting thousands of published papers on PubMed weekly, pulling data from disparate sources like GitHub and clinicaltrials.gov, and incorporating unique content from dynamic social networks like Substacks and Twitter.
Imagine a collection of AI bots that empower the Jills and FAM177A1 Research Foundations of the world both operationally and scientifically — collectively, CureGPT. Like having your own Lt. Commander Data at your side on your Cure Odyssey!
CureGPT will monitor the published literature and preprint servers in real-time, automating PubMed and Google alerts for keywords like your disease gene and specific symptoms. After having trained on your entire Gmail corpus, CureGPT will then automatically compose emails in your voice inviting the researcher you’ve never heard of but who just published on your gene that you have a care package of cell lines and reagents with their name of it, as well as a community of funded researchers already working on the disease to support them. CureGPT will do this every day for you, without fail or complaint.
Instead of waiting for the scientists to come to you, CureGPT will enable you to go directly to the science. Families and foundations will have to work for it and put in hours of homework. AI will be their steadfast co-pilot.
There will be human co-pilots too! At Perlara, we like to think that’s what Cure Guides are already doing. Seeing around the next corner, Cure Guides will be the prompt engineers of CureGPT. Cure Guides will also tap into their meatspace social networks in order to perform tasks that the AI can’t do, at least for the foreseeable future.
Working with Jill from FAM177A1 Research Foundation, we took the differential diagnosis method to MedTwitter. A single tweet led to a flood of high-signal replies, including one from Aleksandra Foksinka, program coordinator at the Hugh Kaul Precision Medicine Institute at UAB. Aleksandra’s “tweferral” led to a series of emails and ultimately a Zoom consult a few weeks later with a team from the Cincinnati Children’s Undiagnosed and Rare Liver Disease Center (CURL).
One day sooner than we think, CureGPT will be able to do differential diagnosis with high confidence — and you honestly won’t be able to tell if you’re talking to a human or an AI. Whatever you think about the philosophical implications, the productivity unlock will be enormous for ultra-rare families and foundations who choose to coevolve with technology.
As a baby step in the direction of CureGPT-empowered founder parents making the transition from hope-and-prayer foundation to sustainable nonprofit biotech, Cure Guide Helen Hernandez took a stroll with ChatGPT to see if we could connect dots between fragmentary results and preliminary hypotheses about FAM177A1 function.
Here’s the conversation Helen had with ChatGPT exploring the biology surrounding FAM177A1. A paper from 2021 showed that FAM177A1 protein physically interacts with TRAF6. Helen started with TRAF6 as a seed phrase, and went from there. Helen’s comments are italicized. Enjoy!
Prompt: Explain known biological pathways involving TRAF6 with correct references
Date: 4/13/2023
Response: TRAF6 (TNF receptor-associated factor 6) is a signaling protein that plays a crucial role in several biological pathways, including the immune response, inflammation, and bone metabolism. Here are some of the known biological pathways involving TRAF6:
NF-κB pathway: TRAF6 is an essential mediator of the NF-κB signaling pathway, which is activated by various stimuli such as cytokines, pathogens, and stress. TRAF6 binds to the cytoplasmic domain of several receptors, including Toll-like receptors (TLRs) and the receptor activator of NF-κB (RANK), leading to the activation of downstream signaling molecules, including TAK1, IKK, and NIK, ultimately resulting in the activation of NF-κB transcription factors. The NF-κB pathway plays a crucial role in regulating the immune response, inflammation, and cell survival. (1)
MAPK pathway: TRAF6 also activates the mitogen-activated protein kinase (MAPK) signaling pathway, which regulates cell growth, differentiation, and apoptosis. TRAF6 interacts with TAK1 and TAB1, leading to the activation of MAPK kinases (MKKs), including MKK3, MKK4, and MKK6, which in turn activate downstream MAPKs, including p38, JNK, and ERK1/2. (2)
mTORC1 pathway: TRAF6 has also been shown to regulate the mammalian target of rapamycin complex 1 (mTORC1) pathway, which controls cell growth and metabolism. TRAF6 binds to the regulatory-associated protein of mTOR (Raptor), a component of the mTORC1 complex, leading to its ubiquitination and degradation. This, in turn, inhibits mTORC1 activity, resulting in the inhibition of protein synthesis and cell growth. (3)
Bone metabolism pathway: TRAF6 is essential for the differentiation and activation of osteoclasts, which are bone-resorbing cells. TRAF6 is recruited to the cytoplasmic domain of RANK and activates downstream signaling molecules, including c-Fos and NFATc1, which are essential for osteoclast differentiation and function. (4)

Follow-up Prompt 1: Given the above relationships, describe downstream consequences of TRAF6 upregulation.
Date: 4/13/2023
Response: Upregulation of TRAF6 can lead to various downstream consequences, depending on the specific biological pathway affected. Here are some examples:
Increased activation of NF-κB: Upregulation of TRAF6 can enhance the activation of the NF-κB pathway, leading to increased expression of pro-inflammatory cytokines, such as TNF-α, IL-1β, and IL-6, as well as genes involved in cell survival, proliferation, and differentiation. This can contribute to the development and progression of inflammatory and autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, and inflammatory bowel disease.
Enhanced activation of MAPKs: Upregulation of TRAF6 can also increase the activation of MAPKs, such as p38, JNK, and ERK1/2, leading to increased cell proliferation, migration, and invasion, as well as enhanced production of pro-inflammatory cytokines and chemokines. This can contribute to the development and progression of cancer, as well as other diseases associated with abnormal cell growth and differentiation.
Increased activation of mTORC1: Upregulation of TRAF6 can lead to the inhibition of mTORC1 activity, resulting in the inhibition of protein synthesis and cell growth. However, prolonged inhibition of mTORC1 can also lead to autophagy, a process by which damaged or unnecessary cellular components are degraded and recycled. Therefore, upregulation of TRAF6 may promote autophagy, which has been implicated in the pathogenesis of various diseases, including cancer, neurodegeneration, and metabolic disorders.
Enhanced osteoclast differentiation and activity: Upregulation of TRAF6 is essential for the differentiation and activation of osteoclasts, which are bone-resorbing cells. Therefore, upregulation of TRAF6 can lead to increased bone resorption and bone loss, contributing to the development of osteoporosis and other bone disorders.
Overall, upregulation of TRAF6 can have various downstream consequences, depending on the specific biological pathway affected, and can contribute to the pathogenesis of various diseases.
“In light of known limitations of ChatGPT I, a human being, sketched out several pieces of the very-well studied TLR-4 system of which TRAF6 is a part. Importantly, TRAF6 is the only published binding partner to the newly discovered FAM177A1 protein, although this is likely to change as research advances and several possible interacting partners are confirmed and refuted. I then sketched out the relationships between various components of the pathway, starting with the published interaction TRAF6 and ubc-13, which functional FAM177A1 disrupts. (Liao 2021)
Since FAM177A1 negatively regulates TRAF6, the above line of questioning is a proxy for the same directional consequences. Likely because there is such a wealth of information already generated on this pathway, ChatGPT got several key relationships correct. The increase of NF-kappa Beta, IL-1Beta, MAPKs, ERK1/2 are denoted in the above human-developed diagram produced well in advance of the prompt. In spite of this exciting result, it is still important to rigorously verify information generated by ChatGPT.”
Follow-up Prompt 2: Suggest small molecules to reverse several of the specific consequences described above and list rationales for each with proper references
Date: 4/13/2023
Response: Here are some examples of small molecules that have been shown to reverse the specific consequences of TRAF6 upregulation:
NF-κB inhibition: Several small molecules, such as curcumin, resveratrol, and celastrol, have been shown to inhibit the activation of NF-κB, leading to reduced expression of pro-inflammatory cytokines and chemokines. Curcumin, in particular, has been shown to inhibit TRAF6-mediated NF-κB activation by disrupting the interaction between TRAF6 and its downstream signaling molecules, such as IRAK1 and TAK1 (Woo et al., 2015). Resveratrol and celastrol, on the other hand, have been shown to inhibit NF-κB activation by suppressing the phosphorylation and degradation of IκBα, an inhibitor of NF-κB (Chen et al., 2015; Sun et al., 2017).
MAPK inhibition: Several small molecules, such as SB203580, SP600125, and U0126, have been shown to inhibit the activation of MAPKs, leading to reduced cell proliferation, migration, and invasion, as well as reduced expression of pro-inflammatory cytokines and chemokines. SB203580 and SP600125 are selective inhibitors of p38 and JNK, respectively, while U0126 is a selective inhibitor of ERK1/2 (Lee et al., 2016; Tsai et al., 2017; Guo et al., 2018).
mTORC1 activation: Small molecules that activate mTORC1, such as rapamycin and its analogs, have been shown to increase protein synthesis and cell growth, leading to reduced autophagy. Rapamycin and its analogs inhibit the activity of mTORC1 by binding to its intracellular receptor, FKBP12, and blocking the downstream signaling cascade (Laplante and Sabatini, 2012). Therefore, inhibition of TRAF6-mediated mTORC1 inhibition by small molecules, such as rapamycin analogs, may lead to increased protein synthesis and cell growth, and reduced autophagy.
Osteoclast inhibition: Several small molecules, such as bisphosphonates, have been shown to inhibit the differentiation and activity of osteoclasts, leading to reduced bone resorption and bone loss. Bisphosphonates, in particular, inhibit the activity of farnesyl pyrophosphate synthase, an enzyme involved in the biosynthesis of isoprenoid compounds that are required for osteoclast function (Russell et al., 2008).
Overall, these small molecules have the potential to reverse the specific consequences of TRAF6 upregulation, depending on the specific biological pathway affected, and may have therapeutic potential for the treatment of various diseases associated with TRAF6 dysregulation. However, it is important to note that further research is needed to determine the efficacy and safety of these small molecules in clinical settings.
Prompt 2: List 50 scientists who have co-authored Review Articles focused on TRAF6 across multiple fields (cancer, immunology, osteology). Include proper references and up-to-date affiliations
Date: 4/13/2023
“It could not. See comment for the detailed response that amounts to ‘no.’”
NEXT PROMPT: Given the understanding generated above, how would a state of TRAF-6 upregulation be expected to affect the following proteins: VPS13B, SLC27A2, TGS1, CDK17. Support each conclusion with detailed explanations and multiple correct citations
There is limited research on the specific interaction between TRAF6 and the proteins VPS13B, SLC27A2, TGS1, and CDK17. Therefore, it is difficult to predict with certainty how upregulation of TRAF6 would affect these proteins. However, here are some possible hypotheses based on the available literature:
VPS13B: VPS13B is a large, multi-domain protein that is involved in the regulation of intracellular vesicle trafficking and organelle homeostasis. While there is no direct evidence of an interaction between VPS13B and TRAF6, some studies have suggested that TRAF6 may indirectly affect the function of VPS13B by regulating the activity of the NF-κB pathway, which has been implicated in vesicle trafficking and organelle biogenesis (Kato and Mano, 2015; Hu et al., 2018). Therefore, it is possible that upregulation of TRAF6 may lead to dysregulation of the NF-κB pathway, which in turn could affect the function of VPS13B and lead to abnormal vesicle trafficking and organelle dysfunction.
SLC27A2: SLC27A2 is a member of the solute carrier family of transporters that is involved in the uptake and transport of long-chain fatty acids into cells. There is no direct evidence of an interaction between SLC27A2 and TRAF6, but some studies have suggested that dysregulation of the NF-κB pathway, which is activated downstream of TRAF6, can affect the expression of fatty acid transporters such as SLC27A2 (Kamagate et al., 2008; Park et al., 2015). Therefore, upregulation of TRAF6 may lead to activation of the NF-κB pathway and altered expression of SLC27A2, potentially affecting the transport and metabolism of fatty acids in cells.
TGS1: TGS1 is a protein involved in the processing and maturation of transfer RNA (tRNA) molecules. There is no direct evidence of an interaction between TGS1 and TRAF6, and the function of TGS1 is not known to be regulated by the NF-κB pathway. Therefore, it is unclear how upregulation of TRAF6 would affect the function of TGS1.
CDK17: CDK17, also known as PCTAIRE1, is a member of the cyclin-dependent kinase family of proteins that is involved in cell cycle regulation and neuronal development. There is no direct evidence of an interaction between CDK17 and TRAF6, but some studies have suggested that TRAF6 may indirectly affect the function of CDK17 by regulating the activity of the MAPK pathway, which has been implicated in cell cycle regulation and neuronal differentiation (Li et al., 2015; Lu et al., 2021). Therefore, upregulation of TRAF6 may lead to dysregulation of the MAPK pathway, which in turn could affect the function of CDK17 and lead to abnormal cell cycle regulation and neuronal development.
Overall, while there is limited direct evidence of an interaction between TRAF6 and the proteins VPS13B, SLC27A2, TGS1, and CDK17, it is possible that upregulation of TRAF6 could indirectly affect the function of these proteins through dysregulation of downstream signaling pathways. However, further research is needed to fully understand the potential consequences of TRAF6 dysregulation on these proteins.

Followup Prompt 2: Can you describe 5 different ways upregulation of the MAPK pathway would impact CDK17 function with several references?
Sure! Here are five different ways that upregulation of the MAPK pathway could impact CDK17 function, along with several references to support each point:
Activation of MAPK signaling may increase CDK17 expression: The MAPK pathway can regulate the expression of CDKs, and specifically, upregulation of the MAPK pathway may increase CDK17 expression. For example, a study found that treatment of prostate cancer cells with EGF, which activates the MAPK pathway, led to increased CDK17 expression (Shen et al., 2018).
MAPK-mediated phosphorylation of CDK17 may enhance its activity: MAPKs can phosphorylate CDKs, and this phosphorylation can regulate CDK activity. For example, a study found that phosphorylation of CDK17 by MAPKAPK2 enhanced its kinase activity (Cargnello et al., 2011).
Activation of MAPK signaling may promote CDK17 nuclear localization: MAPK signaling can regulate the localization of CDKs within the cell, and upregulation of the MAPK pathway may promote the nuclear localization of CDK17. For example, a study found that activation of the MAPK pathway by growth factors led to the nuclear localization of CDK17 in prostate cancer cells (Shen et al., 2018).
Upregulation of the MAPK pathway may increase CDK17-mediated phosphorylation of downstream targets: CDK17 can phosphorylate a number of downstream targets, and upregulation of the MAPK pathway may increase the phosphorylation of these targets. For example, a study found that CDK17 phosphorylates the transcription factor STAT3, and that upregulation of the MAPK pathway by EGF treatment increased CDK17-mediated phosphorylation of STAT3 (Shen et al., 2018).
MAPK pathway activation may lead to increased CDK17-mediated cell proliferation: CDK17 has been implicated in the regulation of cell proliferation, and upregulation of the MAPK pathway may promote cell proliferation via CDK17. For example, a study found that knockdown of CDK17 inhibited the proliferation of prostate cancer cells, and that activation of the MAPK pathway by EGF treatment increased CDK17-mediated cell proliferation (Shen et al., 2018).

Followup Prompt 3: Can you identify each word from the previous prompt that is above an 8th grade reading level and provide a simple explanation for the term?
Sure! Here are the terms from the previous prompt that may be above an 8th grade reading level, along with simple explanations:
Upregulation: This term refers to an increase in the activity or expression of a particular gene, protein, or pathway. For example, upregulation of a signaling pathway can lead to more activity within that pathway.
MAPK pathway: This is a signaling pathway within cells that is involved in the regulation of many different cellular processes, including cell growth, differentiation, and survival. MAPK stands for "mitogen-activated protein kinase," and the pathway is activated by a variety of signals, including growth factors and stress.
CDK17: This is a protein known as cyclin-dependent kinase 17. CDKs are a family of proteins that play a key role in the regulation of cell cycle progression and other cellular processes.
Phosphorylation: This is a process by which a phosphate group is added to a molecule, typically a protein. Phosphorylation can regulate protein function, often by activating or deactivating a protein.
Nuclear localization: This term refers to the location of a protein within a cell. Nuclear localization refers to the presence of a protein within the nucleus of a cell.
Transcription factor: This is a protein that binds to DNA and regulates the expression of genes. Transcription factors play a key role in the regulation of many different cellular processes, including development and differentiation.
Proliferation: This term refers to the growth or multiplication of cells within an organism or tissue. Cell proliferation is a normal part of many physiological processes, including tissue repair and growth, but can also be a hallmark of cancer.
