Rac1 is a small GTPase, the hyperactivation of which is linked to tumor progression and drug resistance. The oncogenic variant Rac1b has been shown to be overexpressed in cancers, such as colorectal cancer (CRC), and it has also been correlated with poor prognosis and CRC resistance to oxaliplatin.
In tumors with amino acid deprivation, eIF-2α kinase GCN2 is activated and triggers a signaling response to promote cell survival and proliferation. This is important in high metabolically active hematological cancers, such as acute myeloid leukemia (AML).
The generation of pathogenic autoantibodies is a crucial event in the development of inflammation and complement activation, leading to immune cell responses.
Vanishing white matter disease (VWM) is a rare and progressive leukoencephalopathy caused by loss-of-function mutations, in a recessive pattern of inheritance, in any of the genes encoding eIF2B, a guanine nucleotide exchange factor for eIF2 and an effector of the integrated stress response (ISR). At last week’s American Academy of Neurology meeting, Calico Life Sciences LLC and Abbvie Inc. presented preclinical results for their brain-penetrant compound ABBV-CLS-7262 (fosigotifator sodium tromethamine) in VWM.
AR-V7 is the most clinically relevant androgen receptor (AR) splice variant associated with endocrine resistance and poor prognosis in patients with prostate cancer.
Steroid-resistant nephrotic syndrome (SRNS) is a disease characterized by hypoalbuminemia, proteinuria, edema and hyperlipidemia, and a cause of chronic kidney disease in the pediatric population.
Researchers from Zhuhai Grit Biotechnology Co. Ltd. recently presented preclinical characterization of a new genetically modified tumor-infiltrating lymphocyte (TIL) product, GT-216, being developed for the treatment of solid tumors.
Researchers from Biocytogen Pharmaceuticals (Beijing) Co. Ltd. presented the development of a humanized VEGFA model (B-hVEGFA mice) as a new tool for in vivo testing of VEGFA-targeting therapeutics.
Using its artificial intelligence/machine learning platform, Aurigen, Auron Therapeutics Inc. has identified histone acetyltransferase KAT2A/B as a driver of tumor cell plasticity and designed new small-molecule degraders of KAT2A/B.
Dysfunction of the complement system plays an important role in the pathogenesis of renal diseases. Complement inhibitors, such as C5 inhibitors, have shown efficacy in clinical trials, but may not be sufficient to block disease progression as monotherapy.
