Ovarian cancer remains unresponsive to immune checkpoint inhibitors due to its ability to suppress cytotoxicity from immune cells that are infiltrating the tumor, where the O-glycosylation pathway may be disrupted. Precision Biologics Inc. is developing PB-vcMMAE-5, an antibody-drug conjugate composed of the monoclonal antibody PB-223, which targets tumor-specific truncated core-2 O-glycans, conjugated to microtubule inhibitor MMAE and with a drug-to-antibody ratio of 3.92.
Generating gametes from nonreproductive tissues could help overcome infertility. Previous studies have successfully transformed stem cells into viable oocytes through cellular reprogramming. Scientists at Oregon Health & Science University (OHSU) developed a method to derive them from skin cells via somatic cell nuclear transfer (SCNT), unlocking a mechanism that blends mitosis and meiosis. Now, the researchers have taken another step forward by generating fertilizable eggs from human skin cells.
Antengene Corp. Ltd. and Antengene Discovery Ltd. have divulged phospholipid hydroperoxide glutathione peroxidase, mitochondrial (PHGPx; GPX4) inhibitors acting as ferroptosis inducers reported to be useful for the treatment of cancer.
Jiangsu Synthgene Biotechnology Co. Ltd. has synthesized platinum complexes acting as radiosensitizers reported to be useful for the treatment of cancer.
Voronoi Inc. has disclosed heteroaryl compounds acting as Myt1 kinase (PKMYT1) and/or Wee1-like protein kinase (Wee1) inhibitors reported to be useful for the treatment of cancer.
Biolinerx Ltd. and Hemispherian AS have established a joint venture (JV) to develop GLIX-1, Hemispherian’s lead drug candidate being developed as a potential treatment for newly diagnosed and recurrent glioblastoma.
Two independent studies applied CRISPR-based genetic editing – one to treat leukemia and the other to target myeloma – to overcome the challenges faced by CAR T cells, such as exhaustion, impaired activation and fratricide, a phenomenon in which they attack each other.
In cancer, Cdc37 is phosphorylated by casein kinase 2 (CK2) and then the phosphoprotein binds to various kinase ‘clients’ and to the chaperone Hsp90. Hsp90 facilitates the folding of the clients into fully active forms to drive the cell cycle. The plant-derived quinine methid triterpenoid celastrol can inhibit the interaction between Hsp90 and Cdc37 and thereby slow cancer growth by arresting the cell cycle and inducing apoptosis. However, researchers at China Pharmaceutical University China wanted to inhibit the ‘Hsp90-Cdc37-kinase’ cycle at multiple points simultaneously for greater therapeutic effect.
