Protein phosphatase 2A (PP2A) is a heterotrimer affecting approximately 60% of all serine/threonine phosphorylations. PP2A functions as a tumor suppressor when it is a trimer (PP2A-A-PP2Ac-B56) containing the B56 subunit. The B56 subunit is known to interact with up to 100 different proteins, but exactly how the PP2Aa/c-B56 complex is disrupted to initiate cancer has been poorly understood until now.
Researchers at Shanghai Institute of Materia Medica of the Chinese Academy of Sciences have developed urea compounds containing 2-heteroaromatic ring substitution that act as cyclin-dependent kinase 9 (CDK9) inhibitors.
A recent Moya Bio Ltd. patent describes fused azole and furan-based nucleoside analogues acting as ubiquitin-like modifier-activating enzyme 1 (UBA1; UBE1) inhibitors and thus reported to be potentially useful for the treatment of inflammation, cancer, parasitic infections and autoimmune diseases.
Researchers from Tonix Pharmaceuticals have presented preclinical data for mTNX-1700 (mTTF2-MSA), a novel recombinant fusion protein with an extended half-life, in anti-PD-1 treated colorectal cancer (CRC) models.
It has been previously demonstrated that necrosis is associated with metastatic dissemination of cancer cells; however, how necrosis promotes tumor dissemination is not understood. In a recent study, researchers from Fred Hutchinson Cancer Center and University of Washington aimed to investigate the correlation between tumor dissemination and the formation of large contiguous zones of necrosis within the tumor core.
Researchers from Memorial Sloan Kettering Cancer Center and affiliated organizations presented data from a study that aimed to investigate the immunomodulatory functions of lysine-specific demethylase 1 (LSD1) in regulating MHC-I antigen presentation pathway (APP) and resistance to immunotherapy in patients with small-cell lung cancer (SCLC).
CD73 is known to induce immune evasion in solid tumors by release of immune-suppressive adenosine in the tumor microenvironment. Researchers from Cidara Therapeutics Inc. have presented preclinical data on the CD73 inhibitor drug FC-conjugate CBO-212 for the potential treatment of solid tumors.
IOA-244 is a selective phosphoinositide 3-kinase delta (PIK3δ) inhibitor that is being tested in the clinic for lymphoma and solid tumors. Researchers from Ionctura SA and their collaborators tested IOA-244’s antiproliferative activity in MTT assays at 72 h.
Two molecules that affected the cell cycle only of acute myeloid leukemia (AML) cells could be used as a clinical strategy against this pathology. Scientists at Memorial Sloan Kettering Cancer Center and Harvard University have discovered that DEG-35 and DEG-77 arrested the cell cycle and promoted cell differentiation and apoptosis in these cells.
Researchers from Onxeo SA presented preclinical data for OX-425, a first-in-class oligodeoxynucleotide that operates as a poly (ADP-ribose) polymerase 1 (PARP-1) decoy, and which is being developed as anticancer agent.
