Article Title: Fine-Tuning Roles of Endogenous Brain-Derived Neurotrophic Factor, TrkB and Sortilin in Colorectal Cancer Cell Survival

doi: 10.1371/journal.pone.0025097

Figure Lengend Snippet: (A) Role of endogenous BDNF and its receptor TrkB on CRC cell proliferation: effects of exogenous BDNF and suppressing endogenous TrkB receptor on cell proliferation. The four cell lines were cultured for 24 h in FCS-free medium (FCS 10%, −) in the presence of exogenous BDNF (+), K252a (+) alone or in combination. Cell proliferation was determined by flow cytometry analysis using EdU Alexa Fluor 488. The data are presented as histograms of proliferating cells in relative units ± SEM of five independent experiments. *, p <0.05; **, p <0.01; ***, p <0.001, when compared with serum-free medium. (B, C) Effects of exogenous BDNF and suppressing endogenous TrkB receptor on cell survival. Apoptotic ratios of soluble nucleosomes were detected by ELISA Cell for WiDr, SW480, SW620, and COLO 205 induced by serum deprivation alone (FCS 10%, −) or in association either with exogenous BDNF (+), or with K252a (+), during 24–72 h of serum deprivation. Histograms, mean ratio of apoptotic cells ± SEM of at least three independent experiments. *, p <0.05; **, p <0.01; ***, p <0.001, when compared with serum-free condition alone. (D, E) apoptotic ratio after 24 h serum deprivation alone (0% FCS) or with combination with a neutralizing anti-BDNF mAb (0% anti-BDNF). Histograms, mean ratio of apoptotic cells ± SEM of three independent experiments. *, p <0.05; **, p <0.01; ***, p <0.001, when compared with serum-free condition alone.

(C) Colocalization of pro-BDNF and sortilin. Confocal microscopy study of a WiDr cells stained with an anti-pro-BDNF Ab (green) and an anti-sortilin Ab (red), and double staining (yellow) after 24 h of serum deprivation. (D, E) apoptotic ratios after 24 h serum deprivation alone (0% FCS) or combined with recombinant Pro-BDNF (0% Pro-BDNF). Histograms, mean ratio of apoptotic cells ± SEM of three independent experiments. *, p <0.05; **, p <0.01; ***, p <0.001, when compared with serum-free condition alone (0% FCS).

doi: 10.3389/fendo.2022.1069404

Figure Lengend Snippet: BDNF Signaling. (A) Prefrontal cortex total TrkB, pTrkB (AU) and pTrkB/total TrkB ratio. (B) Hippocampus total TrkB, pTrkB (AU) and pTrkB/total TrkB ratio. (C) Prefrontal cortex total CREB, pCREB (AU) and pCREB/total CREB ratio. (D) Hippocampus total CREB, pCREB (AU) and pCREB/total CREB ratio. All graphs are accompanied by representative blots. All data analyzed using a two-way ANOVA, TrkB, tropomyosin receptor kinase B; CREB, cAMP response element-binding protein; AU, arbitrary units; SED, sedentary; VWR, voluntary wheel running; OVX, ovariectomized; SHAM, sham operated. Significance is set to *P ≤ 0.05; **P ≤ 0.005; P ≤ 0.05; n=10 per group.
