Effects of Colchicine and Colchemid on Synthesis of Deoxyribonucleic Acid in the Skin of the Guinea...
Nature· 5 days agoExperiments were performed to determine whether colchicine and colchemid, at the concentrations normally used, had any direct and immediate action on the initiation and rate ...
Avoiding commitment - Nature Reviews Molecular Cell Biology
Nature· 5 days agoIn eukaryotic cells, DNA is packaged into chromatin, which controls gene expression in part by limiting the access of transcription factors to DNA. It might ...
Does STRESS really cause cancer? Here's what leading experts say...
Daily Mail· 2 days ago'Stress and cortisol can also suppress the immune system.' Scientists have also tried to mimic the...
Emergence of large-scale cell death through ferroptotic trigger waves - Nature
Nature· 7 days agoFerroptosis can propagate across human cells over long distances (≥5 mm) at constant speeds (around 5.5 μm per minute) through self-regenerating waves of reactive oxygen species; such waves ...
Centrosome biogenesis and function: centrosomics brings new understanding - Nature Reviews Molecular...
Nature· 5 days agoRecent large-scale functional genomics and proteomics analyses have revealed novel molecules that are involved in regulating centrosome function and biogenesis. Other studies indicate that certain ...
PTBP1 protects Y RNA from cleavage leading to its apoptosis-specific degradation - Cell Death...
Nature· 5 days agoSome RNAs such as 28S rRNA, U1 small nuclear RNA (snRNA), and Y RNAs are known to be cleaved during apoptosis. The underlying mechanism, functions, and biological significance of RNA degradation ...
Nuclear actin assembly is an integral part of decidualization in human endometrial stromal cells -...
Nature· 6 days agoNuclear actin assembly occurs during decidualization of human endometrial stromal cells. This contributes to cell differentiation by inducing cell cycle arrest for establishing the decidualized state of endometrial stromal cells.
Mechanisms of transcriptional memory - Nature Reviews Molecular Cell Biology
Nature· 5 days agoHow can the same gene remember that it is 'off' in one cell lineage and 'on' in another? Studies of how homeotic genes are regulated in Drosophila melanogaster have uncovered a transcriptional ...
