Scientists from the University of Lisbon have described how telomeres can establish the maximum damage that a cancer cell can suffer. Above this threshold, the cell would stop dividing and die. The damage comes from the transcription of the telomeres themselves of an RNA molecule called TERRA. When TERRA’s levels increase, the cell can no longer multiply. This mechanism occurs in ALT (alternative lengthening of telomeres) cells, which do not elongate their telomeres through telomerase.
Insilico Medicine IP Ltd. has described new TRAF2 and NCK-interacting protein kinase (TNIK) and/or mitogen-activated protein kinase kinase kinase kinase 4 (MAP4K4; HGK; MEKKK4) inhibitors reported to be useful for the treatment of cancer and fibrosis.
Polycomb repressive complex 2 (PRC2) is composed of several subunits, such as EZH2, EED and SUZ12, and is a regulator of cell proliferation and development. Targeting the allosteric subunit EED may be a new approach for fully inhibiting PRC2 complex activity and addressing the limitations of EZH2 inhibition.
Immune checkpoint inhibitors are useful for the treatment of solid tumors, but in many tumors, only partial response is achieved. The antitumoral efficacy of Enlivex Therapeutics Ltd.'s Allocetra-OTS, a cellular therapy, was investigated in animal models of solid tumors.
Researchers from Janssen Pharmaceutica NV reported the discovery of novel potent fluoroallylamide induced myeloid leukemia cell differentiation protein Mcl-1 inhibitors for the treatment of hematologic malignancies.
GPC3 is an oncofetal antigen highly expressed in hepatocellular carcinoma (HCC) but minimally expressed in adult normal tissues, except the placenta. Cytovia Therapeutics Inc. has presented preclinical data on CYT-303, a bispecific natural killer (NK) engager targeting NK cell-activating receptor NKp46 and GPC3 expressed in tumor cells.
Epidermal growth factor receptor (EGFR) is a target in many cancers, but EGFR inhibitors have displayed little utility in treating glioblastoma (GBM) due to limited blood-brain barrier (BBB) penetration.
