WebIn contrast to the decrease in PGC-1α, estrogen increased protein levels of nuclear respiratory factor 1, a known PGC target and mediator of mitochondrial biogenesis. The latter effect of estrogen was independent of PI3K, suggesting a separate mechanism consistent with increased expression of PGC-1β and PRC. WebJun 28, 2024 · For example, the nucleolus, the site of ribosome biogenesis, is formed around the ribosomal RNA (rRNA) transcription sites. ... a nucleolus-like structure is newly formed at the site. 40, 41 The paraspeckle is a nuclear body involved in RNA editing and gene regulation, ... and how it regulates nuclear functions such as gene expression and ... WebSep 16, 2024 · Nucleolus, as the largest nuclear body, is regarded as a central hub in coordinating cellular stress response by regulating ribosome subunit biogenesis and cell cycle progression. In response to stress, nucleolus can control the activity of the tumor suppressor protein p53 or crosstalk with Cajal bodies (Boulon et al., 2010 ). dr seeto cherrybrook
