Imaging mass cytometry showcases odd numbers of proteins in kidneys of lupus patients, identifying novel markers for disease. The study found decreased and increased disease markers pointing to renal disease, with potential enlargement of glomeruli in some patients.
Researchers found that expression of transcription factors contributes to different subtypes of colorectal cancers. The degree of DNA methylation varies across tissue types, with some cancers having high and others low frequency of methylation gains. Studying transcription factor expression may help determine overall survival in patien...
Researchers investigate MCL-1i-induced Mcl-1 protein accumulation and its implications in B-cell malignancies. The study reveals a complex mechanism contributing to MCL-1 protein stability upon treatment with MCL-1 inhibitors.
The study found that drug-resistant Leishmania parasites have distinct protein production profiles compared to sensitive parasites, suggesting a global reprogramming of protein synthesis. This pre-emptive adaptation enables the parasite to quickly respond to the presence of the drug and survive when it is absent.
A new study published in Aging-US has identified the p53-p16/RB-E2F-DREAM complex as a critical regulator of cellular senescence. The researchers found that this complex represses multiple target genes involved in cell cycle regulation, DNA repair, and chromatin structure, leading to the stability of the senescent arrest.
Researchers found that p21 knockout mice experienced reduced senescent cell presence, alleviated chronic lung inflammation, and improved fitness. Resident epithelial and endothelial cells played a significant role in mediating the p21-dependent inflammatory response.
