Randomized trial uncovers the role of 5-HT2B receptor in regulating cell-cycle progression, indicating potential therapeutic targets.

This research aims to understand how 5-HT2B receptor activation influences cell-cycle progression via various signaling pathways.
Characterization of 5-HT2B receptor activation in cell lines
Utilization of PDGFR inhibitors and c-Src inhibitors
Analysis of cyclin D1 and cyclin E levels and cell cycle effects
5-HT2B activation leads to increased cyclin D1 expression through MAPK pathways, while cyclin E is independently regulated.
Inhibition of c-Src blocks the activation of PDGFR and downstream effects on cyclins and cell division.
PDGFR kinase activity is essential for 5-HT2B receptor-mediated signaling.

Nebigil et al. (2000) studied this question.
