Example sentences for: peaking

How can you use “peaking” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Among genes that are stimulated by FSH/cAMP during the period of maturation of Sertoli cells (15 to 20 days of age in rats), are several subunits of cAMP-dependent protein kinase (PKA), the serine/threonine kinase mainly responsible for the downstream effects of FSH [ 15 ] . Expression of the RIIβ regulatory subunit of cAMP-dependent protein kinase is highly induced (50-fold) at the mRNA level in primary cultures of rat Sertoli cells as a late response to cAMP peaking at 12 hours [ 16 ] . We have demonstrated that expression of CAAT/Enhancer binding protein β (C/EBPβ) is induced by cAMP with rapid kinetics in Sertoli cells, and that C/EBPβ is responsible for induction of late response genes like the RIIβ-gene [ 17 ] . The RIIβ promoter contains a conserved E-box/HLH element in the basal promoter localized at -280 to -275 relative to the functional ATG [ 18 ] . This element is shown to be important for cAMP-responsiveness in granulosa cells, and it has been shown to bind both USF and Myc in CHO and NB2a cells [ 18 19 ] . In this work, we show that USF isoforms may regulate cAMP responsiveness of the RIIβ promoter by modulating the effect of C/EBP, and that the formation of USF isoforms may be regulated by cAMP in Sertoli cells.

  • The film is based on a book by Joe Connelly, who cruised the streets of Manhattan in an ambulance from the mid-'80s to the early '90s, when the crack epidemic was peaking and New York had become the embodiment of everything untenable about major American cities.

  • NewsHour's Mark Shields says that Bradley aides are actually worried about peaking too soon.

  • However, the authors warned that the high percentage of HCoV-NL63-positive samples could be due to a strong viral activity in the study year, and long-term studies are needed to determine whether HCoV-NL63 infections occur in cycles peaking every two to three years, as observed for other respiratory viruses.

  • Remarkably, resistin levels rose dramatically because of endotoxemia, peaking 8–16 h after LPS administration (Figure 5A).
