Mechanisms linking cytoplasmic decay of translation-defective mRNA to transcriptional adaptation Transcriptional adaptation (TA) is a genetic robustness mechanism through which mutant messenger RNA (mRNA) decay induces sequence-dependent up-regulation of so-called adapting genes. How cytoplasmica...

This is a fascinating paper that reveals defined and clear mechanism for a phenomenon that for some seemed unbelievable- the up regulation of genes paralogous to those with specific types of inactivating mutations. This is called transcriptional adaptation 1/ www.science.org/doi/10.1126/...

How does the piRNA pathway solve the self vs. non-self problem? ๐Ÿงฌ

Since piRNAs come from single-stranded RNA, how does the cell choose the right ones? For years, "piRNA clusters" were seen as THE privileged source. But are they really special and earmarked for biogenesis? (1/19)

Evaluating phase separation in live cells: diagnosis, caveats, and functional consequences - PubMed The idea that liquid-liquid phase separation (LLPS) may be a general mechanism by which molecules in the complex cellular milieu may self-organize has generated much excitement and fervor in the cell biology community. While this concept is not new, its rise to preeminence has resulted in renewed in โ€ฆ

"We find that the evidence for in vivo LLPS is often phenomenological and inadequate to discriminate between phase separation and other possible mechanisms. Moreover, the causal relationship and functional consequences of LLPS in vivo are even more elusive"
