Although radiotherapy is widely used in cancer treatment, its effects on the tumor microenvironment (TME) can be immunosuppressive as well as immunostimulatory. Fibroblast activation protein (FAP) is expressed by cancer-associated fibroblasts (CAFs) in several tumors, with higher levels linked to a weakened immune response to immune checkpoint blockade in patients.
Researchers at the University of California San Diego have uncovered a key mechanism underlying the treatment resistance of melanoma with the BRAF V600E mutation through pathways involved in focal adhesion and extracellular matrix (ECM) remodeling. These two processes remodel the tumor cell environment in melanoma through the RAF/MEK cell signaling pathway. However, the combined use of FAK inhibitors with a RAF-MEK clamp overcame this resistance.
RAS G12D is one of the most frequent mutations in RAS, and when it occurs, it leaves RAS in a permanently active state, causing the cell to proliferate uncontrollably. Examples of the so-called RAS-addicted cancers are colorectal cancer or pancreatic ductal adenocarcinoma.
Immunostimulant therapy using agonistic cytokines or activating antibodies has been associated with off-target side effects, failure to preferentially activate cytotoxic lymphocytes (CTLs) over regulatory T cells (Treg), and the development of T-cell exhaustion. With the aim of overcoming these issues, researchers from Recourse Biologics Inc. designed a potentially first-in-class immunostimulatory fusion protein.
Human antigen R (HuR) controls the stability and translation of several transcripts that are key for metabolism, inflammation and cancer, including TNF-α or MYC. Previous findings have shown the pro-tumorigenic role of HuR in hepatocellular carcinoma (HCC), and its inhibition to be involved in metabolic dysfunction-associated steatohepatitis (MASH).
Multiple endogenous retroviruses (ERVs) in human DNA may be programmed to activate as cancer therapy. A recent study, led by scientists at the Dana-Farber Cancer Institute, expanded on a previously reported case of kidney cancer cure after hematopoietic stem cell transplantation attributed to the expression of an ERV driven by the hypoxia-inducible factor 2 (HIF2). The question was whether this finding might play out with different ERVs and different types of cancer through HIF.
Taichengsi (Shanghai) Biomedical Co. Ltd. has described antibody-drug conjugates comprising an antibody covalently bound to a cytotoxic drug through a bivalent olefin linker optionally consisting of an isotope-labeled compound reported to be useful for the treatment of cancer.
Scientists at Jiangsu Hengrui Medicine Co. Ltd. and Shanghai Hengrui Pharmaceutical Co. Ltd. have synthesized protein arginine N-methyltransferase 5 (PRMT5) inhibitors reported to be useful for the treatment of cancer.
Mindrank Therapeutics (Suzhou) New Drug Research & Development Co. Ltd. has disclosed cellular tumor antigen p53 (TP53) (Y220C mutant) stabilizers reported to be useful for the treatment of cancer.
The map of cystic fibrosis (CF) research is being redrawn in the U.K. as improvements in treatment, and in particular the introduction of CF modulator drugs, mean people with the rare inherited disease are living much longer.
