NB100-2220

Lysates of HeLa parental cell line and LC3B knockout HeLa cell line (KO) untreated (-) or treated (+) with 50 uM CQ for 18 hours. PVDF (Polyvinylidene difluoride) membrane was probed with 0.5 ug/mL of Rabbit Anti-LC3B Polyclonal Antibody (Catalog # NB100-2220) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog# HAF008). A specific band was detected for LC3B at a molecular weight of approximately 15 kDa (as indicated) in the parental HeLa cell line, but is not detectable in the knockout HeLa cell line. GAPDH is shown as a loading control. This experiment was conducted under reducing conditions.

<b>Genetic Strategies Validation. </b>LC3B was detected in immersion fixed CQ treated HeLa cells (left) but was not detected in LC3B knockout HeLa cells (right) using rabbit anti-human LC3B polyclonal antibody (Catalog #NB100-2220) at 0.3 ug/mL for 3 hours at room temperature.

Western Blot: Carbonic Anhydrase IX/CA9 Antibody - BSA Free [NB100-417] - GPRC5A promotes hypoxic cell survival via YAPAHypoxia induced increased total YAP expression in a panel of colorectal cancer cell lines. Actin confirmed equal loading; blots are representative of at least two independent experiments. Related to Fig 4.B–EqRT–PCR analysis revealed that hypoxia increased the expression of known YAP target genes AREG, BCL2L1 (BCL‐XL), CTGF & CYR61. Representative experiments are shown. Representative examples of n = 3 independent experiments are shown; data are presented as mean ± SD.FIncreased expression of YAP Ser397 in GPRC5A‐depleted cells was overridden by expression of constitutively active RhoA (G14V) in hypoxia. Expression of dominant negative RhoA (T19N) did not further increase YAP Ser397 phosphorylation in response to GPRC5A depletion.GDarker exposure of the GPRC5A blot in Fig 4I, confirming expression of 30–40 kDa & 80 kDa species. Note that YAP siRNA partially diminishes GPRC5A in line with the existence of positive HIF‐GPRC5A‐YAP feedback loop.
