Polysome profiling vs ribosome profiling
WebRibosome profiling allows ribosome nuclease-protected RNA fragments to be mapped to transcripts to enable quantitative measurement of the translational efficiency for a … WebN 6-methyladenosine (m 6 A) modification controls cell fate determination. Here, we show that liquid-liquid phase separation (LLPS) of YTH N 6-methyladenosine RNA binding protein 1 (YTHDF1), a pivotal m 6 A “reader” protein, promotes the transdifferentiation of spermatogonial stem cells (SSCs) into neural stem cell-like cells by activating the IκB …

WebOf particular interest are those for ribosomal proteins and metabolic enzymes, the expression levels of which are known to be coupled to cell growth and survival. Polysome profiling and reporter analyses suggest that Lin28 stimulates the translation of many or most of these targets. WebDec 10, 2024 · In polysome profiling, the separation of heavy polysomes starts to lose its accuracy when the number of ribosomes associated with an mRNA exceeds seven or …
WebAug 22, 2024 · We used polysome profiling to show that Hsp90α mRNA is selectively translated, while global translation is inhibited during heat stress. Furthermore, we have identified 2 ribosomal proteins, eL36 and eL42 that modulate Hsp90α expression under both normal and heat shock conditions. WebMethionine starvation caused the most drastic decrease in translation as assessed by polysome formation, ribosome profiling, and a measure of protein synthesis (puromycin-labeled polypeptides) but ...
