Abbvie Inc. has described new proteolysis targeting chimera (PROTA) compounds comprising an E3 ubiquitin ligase-binding moiety covalently linked to tyrosine protein phosphatase nonreceptor type 2 (PTPN2)-targeting moiety reported to be useful for the treatment of cancer, diabetes type 2 and nonalcoholic steatohepatitis.
Microenvironmental factors originating from RAS-mutated cancer stem cells stimulated an angiogenic feedback loop with the surrounding environment causing the expression of leptin and TGF-β receptors on the cancer stem cells. Most significantly, leptin and TGF-β signaling were required for malignant transformation.
The findings, which were published in the Nov. 30, 2022 issue of Nature, raise “the intriguing possibility that many cancer mutations may function to lock into place, rather than set the course of, a path that is predetermined by aberrant crosstalk between a cancer stem cell and its microenvironment,” said senior author Elaine Fuchs, Rebecca C. Lancefield Professor and Howard Hughes Medical Institute investigator at Rockefeller University.
Genhouse Medicine (Suzhou) Co. Ltd. has divulged histone deacetylase 6 (HDAC6) inhibitors reported to be useful for the treatment of cancer, idiopathic thrombocytopenic purpura, rheumatoid arthritis, diabetes, multiple sclerosis, lung, alcoholic liver and Alzheimer's diseases, among others.
Nuvalent Inc. has disclosed amino-substituted heterocycles acting as HER2 (erbB2) (mutant) inhibitors reported to be useful for the treatment of cancer.
PARIS – Damae Medical SAS has just raised nearly $6 million to develop new technology to detect skin cancer noninvasively without need for a biopsy. This series A round was led by BNP Paribas Développement SA and supported by original investors Kurma Partners SA and professional private equity fund, Paris Saclay Seed Fund.
Veriskin Inc. has emerged from stealth mode with a noninvasive technology for skin cancer diagnosis and screening. The hand-held device, called Truscore, is designed to help nonexpert users quickly ascertain if a suspicious skin lesion is cancerous. Truscore works by detecting and interpreting force-induced hemodynamic differences between normal and malignant skin sores. It uses a proprietary artificial neural network-based artificial intelligence algorithm and protocols to differentiate skin cancers from other harmless skin conditions.
Castle Biosciences Inc.'s Decisiondx Diffdx-Melanoma test is now commercially available to help dermatopathologists better characterize melanocytic lesions. About 15% of suspicious pigmented skin lesions cannot be definitively determined to be benign or malignant using common methods. The new gene expression profile test reduces the number of indeterminate results by more than 70%.
RNAi therapeutics specialist Sirnaomics Inc. has wrapped up a $105 million series D financing that will support ongoing clinical development of its cancer and fibrotic disease programs plus work on early stage programs targeting metabolic disease and viral infections. But with both new and existing investors jumping in, the company is also preparing for something bigger: its next phase of growth, including a near-term IPO.
