Dana-Farber Cancer Institute Inc. has disclosed proteolysis targeting chimeras (PROTACs) comprising an E3 ubiquitin ligase-binding moiety coupled to an anaplastic lymphoma kinase (ALK)-targeting moiety through a linker reported to be useful for the treatment of cancer.
Researchers at the Dana-Farber Cancer Institute have been able to identify proteins that were released from muscles during exercise in relatively small quantities. Using their method, the team was able to demonstrate that the neurotrophic factor prosaposin was produced during exercise. Prosaposin is “a well-known CNS neurotrophic factor, but has never been seen to come out of muscle or fat,” Bruce Spiegelman told BioWorld. Spiegelman is a researcher at the Dana-Farber Cancer Institute and Stanley J. Korsmeyer Professor of Cell Biology and Medicine at Harvard Medical School.
Dana-Farber Cancer Institute Inc. and Cornell University have disclosed phosphatidylinositol 5-phosphate 4-kinase type-2 γ (PIP4K2C) inhibitors and its PROTAC compounds reported to be useful for the treatment of cancer, infections, immunodeficiency disorders, insulin resistance, autoimmune and Huntington's disease.
The Dana-Farber Cancer Institute has identified molecular glue degraders comprising a cereblon (CRBN) ubiquitin ligase-binding moiety covalently bound to a zinc finger protein Helios (IKZF2) ligand reported to be useful for the treatment of cancer.
X-chromosome inactivation (XCI) is not unique to female cells and may confer some survival advantage to male cancer cells, according to scientists at the Dana-Farber Cancer Institute at Harvard. The noncoding RNA XIST (acronym for X-inactive specific transcript), which in female mammals (of genotype XX) inactivates one of the X chromosomes, preventing the overexpression of the genes of the repeated chromosome from early stages of embryonic development, also acts somatically in some male cancers, compensating for the loss of the entire chromosome.
“We found that a small percentage of male cancers are expressing XIST, which normally is expressed in female cancers. And the percentage of male cancers that express XIST is variable depending on the cancer type,” Srinivas Viswanathan, researcher in the Department of Medical Oncology at the Dana-Farber Cancer Institute at Harvard and assistant professor of Medicine at Harvard Medical School, told BioWorld.
Tumor mutational burden (TMB), a biomarker used to assess whether a patient will respond to immunotherapy, needs to be recalculated in order to be useful for patients of Asian or African descent. Scientists at the Dana-Farber Cancer Institute found a significant bias in the estimated TMB values affecting these populations and adjusted them for those patients.
Dana-Farber Cancer Institute Inc. has disclosed epidermal growth factor receptor (EGFR) and mutant inhibitors reported to be useful for the treatment of cancer.
Following epigenetic STING (stimulator of interferon genes) derepression, inhibition of the MPS1 kinase strongly reactivated cGAS-STING signaling in mutations in both the oncogene KRAS and the tumor suppressor kinase LKB/STK11. Exploiting these findings could lead to a new therapeutic strategy to target treatment-refractory tumors with mutations in KL tumors, which have mutations in both KRAS and LKB1/STK11.
After a landmark clinical trial of the first POLQ inhibitor in cancer last year, a recently formed U.K. biotech is gearing up to bring a potential rival to the clinic in the coming months. Varsity Pharmaceuticals Ltd., of Cambridge, is planning to begin a phase I trial of novobiocin, a drug previously used as an antibiotic, which has also been found to inhibit the polymerase theta inhibitor (POLQ) pathway.
