p53 mutations are found in 36% of tumors and contribute to the development and progression of cancer. We have tried to develop anti-cancer therapies against p53 mutant tumors before but have been unsuccessful (see x.com/aditharun_/status/1995…). In a recent paper, @Sadagopan_A, @wgibson and team present an elegant approach for targeting tumors that harbor p53 missense mutations. I've been very interested in the p53 drug space and this is clever. I hope they spin this out and try to bring it to patients. They did a lot of detailed cellular experiments to characterize and validate their findings. And, it is presented in a way that non-basic scientists like me can understand. Great writing. Would highly recommend reading the whole piece and please see William's original post (x.com/wgibson/status/1817571…) I'll summarize what I believe to be the key findings and their therapeutic strategy here. p53 missense mutations are dominant negative - a p53 tetramer composed of one mutant subunit is sufficient to stop downstream signaling. However, even when p53 mutations occur, the pathways that sense cell stress are still typically intact and work to activate p53 by increasing its abundance and promoting its nuclear translocation. AND mutant p53 can't drive transcription of MDM2, its destroyer. So, half life of mutant p53 goes from 20 mins to several hours! The only protein whose abundance is significantly increased in p53-mutant cancers is p53 itself (based on CCLE data). The authors translate mutant p53 protein abundance into a cell death signal. They engineer a bifunctional molecule made of p53 binder, linker, and small molecule toxin. Toxin concentrates in p53 mutant cells to cause death after certain level of accumulation in a cell. How to design the toxin? Something with high essentiality and low abundance so a small amount of toxin buildup can neutralize the target and render the cell nonviable. DepMap CRISPR gene essentiality scores and OpenCell protein abundances revealed 5 targets of which PLK1 was chosen mostly because it already has an established ligand previously used to synthesize bifunctional small molecules for targeted protein degradation. So, they put a p53-Y220C binder PEG4'd to PLK1i. PLK1i from BI and p53 Y220C from PMV Pharma ( $PMVP). This molecule kills cells that express p53 Y220C but doesn't kill cells with p53 R273H. This approach is RIPTAC-esque (x.com/aditharun_/status/1995…) but the target protein is a tumor suppressor (p53) here instead of a oncogene (like AR). Components alone did not affect viability much. And, drug given to non-Y220C mutant cells did not impact viability. They observed that when treated with drug, PLK1 colocalized with p53Y220C on chromatin and they speculate that "this mislocalization [of PLK1] could disrupt the function of PLK1 as a mitotic kinase beyond simple steric blockade of its active site". Also, the drug induces apoptosis after 1 day of treatment in target cell type (p53-Y220C cancer cells) at much higher rates than toxin alone given at the same concentration. Also, their drug had specificity for Y220C mutant cell lines. Dose-viability curves here Linker tinkering (peg2, peg4, peg6, c12, c6, c3, etc.) revealed that shorter linkers outperformed longer linkers but PEG2,4,6 all performed similarly. Let's just take the peg4 EC50s which is 850 nM and 2120 nM. Normally, drugs sit at an order of magnitude lower. So, we need to engineer the molecule to be more potent. The opportunity exists to find the right indication / line of therapy / setting, engineer a good bifunctional compound (maybe not PLK1i, maybe something else; better p53 ligand; optimize design for best properties), and try to bring it to market. Very early days here but exciting.

"Though their studies show that, when combined with traditional chemotherapy regimens, patients treated with rAD-p53 live longer post-diagnosis, the interpretation of these results must be put in the context of the finding that p53 mutation status did not significantly influence efficacy outcomes and long-term survival rate for Ad-p53-treated patients" (Zhang et al 2018 The first approved gene therapy product for cancer ad-p53 (gendicine): 12 years in the clinic.

Bridging Protein Sequences and Microscopy Images with Unified Diffusion Models 1. A novel study introduces CELL-Diff, a unified diffusion model that enables bidirectional transformations between protein sequences and their corresponding microscopy images. This model leverages both continuous and discrete diffusion models within a single framework, significantly enhancing the resolution and accuracy of generated protein images compared to previous methods. 2. CELL-Diff integrates cell morphology images, such as those of the nucleus, endoplasmic reticulum, and microtubules, as conditional inputs. This allows the model to generate detailed protein images from sequences and vice versa, providing a powerful tool for investigating subcellular protein localization and function. 3. The model employs a transformer-based U-Net architecture enhanced with cross-attention mechanisms. This design effectively integrates information from both images and sequences, leading to superior performance in both image-to-sequence and sequence-to-image transformations. 4. CELL-Diff was trained on the Human Protein Atlas (HPA) dataset and fine-tuned on the OpenCell dataset. The results demonstrate that CELL-Diff outperforms existing methods in terms of image fidelity and the ability to resolve fine subcellular structures, making it a practical tool for virtual screening of protein localization signals and virtual staining. 5. Potential applications of CELL-Diff include virtual screening of protein localization signals, such as Nuclear Localization Signals (NLS) and Nuclear Export Signals (NES), as well as generating novel protein localization signals. This opens new avenues for studying intracellular protein dynamics and interactions. 6. The study highlights the potential of CELL-Diff to accelerate advancements in therapeutic target identification, drug discovery, and the investigation of biochemical pathways by bridging the gap between protein sequences and their cellular functions as visualized through microscopy. 📜Paper: raw.githubusercontent.com/ml…

3 year ince @Semicon_India and no movement on OpenCell /Display Fab investment. All initial proposals are in limbo. @AshwiniVaishnaw @RajeevRC_X @GoI_MeitY We are ending up with a display module-related upstream investment. Adds some value but is still dependent on imports.
Dixon expects to begin manufacturing display modules by October, followed by the launch of a camera module plant. #MakeInIndia business-standard.com/specia…

Deep generative model for protein subcellular localization prediction 1. deepGPS introduces a pioneering deep generative model that not only predicts protein subcellular localization but also generates synthetic fluorescence images of predicted localizations. This dual-output capability addresses the need for visual insights alongside textual labels in protein localization prediction. 2. By training on both protein sequences and fluorescence images from the OpenCell database, deepGPS accurately predicts nuclear and cytoplasmic localization, outperforming traditional models that rely solely on textual outputs. 3. Unlike existing image-based models that require fluorescence images as inputs, deepGPS functions as a “text-to-image” predictor, making it highly versatile for applications where only sequence data is available. 4. The model leverages ESM-2 and U-Net architectures, integrating advanced encoding of protein sequences and nuclear images to produce high-quality localization predictions with enhanced image realism and spatial accuracy. 5. Further extensions of the model, including deepGPS-single-4 and deepGPS-all, expand its predictive capabilities to multiple organelles and multi-localized proteins, achieving high performance in complex cellular environments. 6. The online openGPS platform provides a user-friendly interface, allowing researchers to submit protein sequences and obtain both localization predictions and visual representations. This interactive feature broadens accessibility and fosters collaborative data expansion within the research community. 7. Comprehensive evaluation demonstrates that deepGPS maintains robustness across cell types and independent datasets, highlighting its generalizability and potential for broader biological and medical applications. 💻Code: github.com/royal-dargon/deep… 📜Paper: biorxiv.org/content/10.1101/… #deepGPS #ProteinLocalization #DeepLearning #SubcellularLocalization #Bioinformatics #GenerativeAI #ProteinResearch
