    Distribution of TRPV1 in salivary gland epithelial cells (SGEC). Representative immunofluorescence labeling of TRPV1 in mSMG (A), hSMG (B), and HSG cells (C). SMGs sections and HSG were immunostained with anti-TRPV1 antibody and AQP5 antibody, then incubated with <t>Alexa</t> Fluor-linked anti-rabbit <t>IgG</t> (red) and Alexa Fluor-linked anti-goat IgG (green). Nuclei (blue) were labeled with 4,6-diamidino-2-phenylindole. (A) TRPV1were mainly detected in apical membrane in acinar cells and in basolateral membrane in ductal cells. AQP5 was used as a marker for acinar cells that was exclusively expressed in the apical membrane of acinar cells (red color). The merged orange color indicates that expression of TRPV1 at the apical membrane in acinar cells. (B) In hSMG, higher expression levels of TRPV1 was observed in ductal cells compared to acinar cells. (C) In HSG cells, TRPV1 was widespread in the cytoplasm. Scale bar indicates 20 µm. The results are representative of four independent experiments.

    Figure Lengend Snippet: FANCJ-R707C fails to suppress single-stranded DNA or Rad51 persistence in cells exposed to CisPt. fancj −/− cells transfected with pEGFP-Vector, pEGFP-FANCJ-WT (FANCJ-WT), pEGFP-FANCJ-R707C (FANCJ-R707C) or pEGFP-FANCJ-H396D (FANCJ-H396D) were exposed for 14 h to CisPt (1 μM) ( A, B ) or APH (200 nM) ( C, D ). Note that for BrdU staining, cells were pre-labeled with BrdU prior to drug exposure as described in Materials and Methods. (A, C) Immunofluorescent BrdU foci (A) or Rad51 foci (C) were detected by Alexa fluor 488 and are shown along with DAPI, or merged (DAPI and Alexa fluor 488). (B, D) Quantitative analyses of BrdU foci (B) or Rad51 foci (D) are shown with S.D. indicated by error bars.

    Article Snippet: After four washes in PBS with 0.1% Tween 20, cells were incubated with Alexa Fluor 488 goat anti-mouse IgG (1:500, Invitrogen) or Alexa Fluor 633 goat anti-mouse IgG (1:500, Invitrogen) for 1 h at room temperature.
