Western Blot: HIF-1 alpha Antibody - BSA Free [NB100-479] - Multiple distinct mechanisms for downregulation of AKT activity in TSC1/2-deficient SCs. A-F: Western blots of sciatic nerve lysates from control & TSC2-SCKO/TSC1-SCKO mice at age P28 (A-E) or P14 (F) (3 mice per group), probed with the indicated antibodies. G: Immunofluorescence of longitudinal frozen sciatic nerve sections from control & TSC2-SCKO mice (age P28) showing greatly increased immunoreactivity of PTEN in the mutant (cytoplasmic signals surrounding DAPI+ nuclei). Scale bars: 50 µm H: Schematic summarizing distinct mechanisms underlying the downregulation of AKT activity in SCs from TSC1/2-SCKO nerves. Components highlighted in red are upregulated while blue highlighting depicts downregulation in mutant nerves. Note downregulation of insulin receptor substrate 1 (IRS-1) by constitutively active S6 kinases downstream of mTORC1. This leads to attenuated activation of PI3K/AKT. Lack of mTORC2 stimulation occurs through abolished TSC1/2 which results in reduced AKT phosphorylation in position Ser473 as well as through feedback inhibition by S6 kinases. Lastly, hyperactive mTORC1 promotes Hif1 alpha transcription factor expression which results in increased PTEN transcription, & thus attenuated PI3K/AKT signaling.

Western Blot: HIF-1 alpha Antibody - BSA Free [NB100-479] - HIF-1 alpha protein increases in HCT116 cells exposed to rapid intermittent hypoxia.

Western Blot: HIF-1 alpha Antibody - BSA Free [NB100-479] - The duration of enhanced radiosensitivity after normoxic pretreatment of cells undergoing Rapid Acute Hypoxia.(A) The RAH protocol is shown with variable delays to radiation after normoxic pretreatment. In this protocol all cells are transiently (25 min) exposed to normoxia for 25 min (+) & then returned to severe hypoxia (1% O2) for 1, 3, or 6 hours prior to radiation. Continuously normoxic cells (NOx) were irradiated as a positive control.

Immunohistochemistry: HIF-1 alpha Antibody (H1alpha67) [NB100-123] - Schematic demonstration of the three HIF1 alpha antibodies used in this study & their epitopes (Figs. 2a & b). Ab1 is a polyclonal antibody raised against N-domain of wild type HIF1 alpha & does not recognize HIF1 alpha 1.2 due to it's different N-terminal part (Fig. 2a). Ab2 & Ab3 are monoclonal & polyclonal antibodies, respectively, with epitopes in the common parts of HIF1 alpha & HIF1 alpha 1.2 (Fig.2a & b). Immunohistochemical analysis performed on thin adjacent sections of NE-differentiated prostate cancer using the HIF1 alpha antibodies Ab1 (Fig. 2c), Ab 2 (Fig. 2d), Ab 3 (Fig. 2e) & HIF1 beta antibody (Fig. 2f). Immunopositivity was detected for HIF1 alpha with Ab2 & Ab3 while HIF1 alpha Ab1 produced no detectable staining. HIF1 beta was also positive in adjacent section (Fig. 2f). Double staining of chromogranin A & androgen receptor antigens on adjacent sections (Fig. 2g) showed immunopositivity for chromogranin A (Fast red). Androgen receptor antibody (DAB, brown) produced no staining. Immunostaining of benign prostate tissue with HIF1 alpha Ab3 showed immunopositivity in NE-like cells of benign prostate tissue (Fig. 2h).

Tumor tissues from Tyr::CreER; BRafV600E; Phd2−/− or Tyr::CreER; BRafV600E mice were processed & analyzed by RPPA assays. The analyses identified proteins that were significantly changed in mouse melanomas compared to nevi. b Activation of Akt–mTOR pathway after phd2 deletion. Tumor tissues were processed & western blots showed stabilization of HIF-1 alpha & HIF-2 alpha proteins after Phd2 depletion. Increased phosphorylation of Akt, 4EBP1 & S6K was observed in tumors from Tyr::CreER; BRafV600E; Phd2−/− compared with those of Tyr::CreER; BRafV600E mice. c Re-expression of Phd2 inhibits the Akt–mTOR pathway. A BRafV600E; Phd2−/− mouse melanoma cell line was established from melanomas in Tyr::CreER; BRafCA; Phd2lox/lox mice. Phd2 was ectopically reintroduced in these tumor cells. Western blot analysis showed that degradation of HIF-1 alpha & HIF-2 alpha proteins with decreased expression of VEGFR2 decreased phosphorylation of Akt, 4EBP1 & S6K. d Pharmacological inhibition (FM19G11) of HIF pathway in BRafV600E; Phd2−/− melanoma cells.

(b,c) An Oncomine analysis of the Staub colorectal database (b) and the Reid database (c) indicate the elevated NQO1 mRNA expression correlates with the increased colorectal cancer grade (n=11 Grade 2, n=14 Grade 3; *P<0.02 with unpaired t-test) and that elevated NQO1 mRNA expression correlates with reduced patient survival at 5 years (**P<0.01 with unpaired t-test), respectively.The gene expression spectrum indicates that colours are z-score normalized to depict relative values within rows (left panel).

$Ten days of IH increases hippocampal HIF1a and disrupts Barnes maze performance in wild-type mice but not in HIF1a+/−. A, left, Representative digitized Western blotting images for HIF1a (103 kDa) and PCNA (40 kDa) in hippocampal nuclear protein fractions from control (n = 4) and IH10 (n = 4). Right, Quantification of HIF1a protein normalized to PCNA revealed that nuclear HIF1a was increased in IH10 when compared with control (p = 0.019). B, Total latency to exit the Barnes maze during three training sessions in control (n = 10) and in IH10 (n = 11). Each blue (control) and red (IH10) line represents an individual performance during training. Training to the exit was conducted over three sessions. Each session was separated by 24 hours. C, Left, During the probe trial, the distance traveled to initially enter the exit zone was shorter in control when compared with IH10 (p = 0.048). Right, Latency to initial entry was smaller in control as well (p = 0.034). D, Heat maps of the mean entry probability across all false exits (1–19) and the exit zone during probe trial for the control and IH10. Comparison of entry probability into the exit zone during the probe trial reveals that control has a greater probability for entering the exit zone when compared with IH10 (p = 0.004). E, Left, Representative digitized Western blotting images HIF1a and PCNA in hippocampal nuclear protein fractions from 0-HIF1a+/− (n = 4) and 10-HIF1a+/− (n = 4). Right, Quantification of HIF1a protein normalized to PCNA revealed that nuclear HIF1a is similar between 0-HIF1a+/− and 10-HIF1a+/− (p = 0.84). F, Total latency to exit the Barnes maze during three training sessions in 0-HIF1a+/− (n = 7) and in 10-HIF1a+/− (n = 8). Each gray (0-HIF1a+/−) and yellow (10-HIF1a+/−) line represents an individual performance during training. All experimental groups exhibit decreased total latency over the course of training.

The DU145FP cells express higher levels of cancer stemness related genes. (A) Transcriptome analyses of prostate cancer stemness-related markers. The Log2 transformed ratio of FPKM values (e.g., FP/WT) are indicated by color-coded index bars. (B) Cells were stained with fluorophore conjugated monoclonal antibodies against CD44 and EPCAM, the antibody against integrin alpha 2 beta 3 without fluorophore conjugation was detected by using secondary antibody conjugated with fluorophore, and stained cells were analyzed by flow cytometry. The scatter plots and histograms show representative results. CTRL denote cell stained with isotype control antibody or only secondary antibody; ST denote cell stained with antibody against EPCAM and integrin alpha 2 beta 3; US denote unstained cells. (C) Immunoblotting confirmation of the protein expression of A-tubulin, GAPDH, SOX9, SLUG, HIF1A, HIF2A, CD44 and integrin alpha 2 beta 3.
