Hypoxia is common in solid tumor masses that has functional consequences for tumor progression. Previous studies demonstrated that nearly 80% renal cell carcinoma (RCC) are under hypoxia. However, effect and its mechanism of hypoxia on RCC cell invasion remains to be defined.

The shRNA expression vectors, which were constructed to express a short hairpin RNA against lncRNA and overexpression of lncRNA, were transfected into the RCC cell lines (SW839 and OSRC-2). Levels of lncRNA-ENST00000574654.1, VEGF-A and VEGF-C mRNA and protein were examined by real-time quantitative-fluorescent PCR and Western blot analysis, respectively. The effects of lncRNA silencing and overexpression on cell invasion of SW839 and OSRC-2 cells were evaluated with cell migration assay.

Hypoxia significantly stimulated cell invasion in both RCC cell lines (SW839 2.38 ± 0.19 of normoxia vs 7.83 ± 0.38 of hypoxia,
< 0.05; and OSRC-2 1.00 ± 0.08 of normoxia vs 5.88 ± 0.32 of hypoxia,
< 0.05). LncRNA microarray analysis found that lncRNA-ENST00000574654.1 was down-regulated under hypoxia. Consistently, over-expression of lncRNA-ENST00000574654.1 resulted in significant blockade of hypoxia-induced RCC migration. Furthermore, expression of lncRNA-ENST00000574654.1 was regulated by HIF-1α and VEGA-A through interacting with hnRNP, which in turn regulated the RCC cell invasion.

These findings suggested that hypoxia promoted RCC cell invasion through HIF-1α/lncRNA (ENST00000574654.1)/hnRNP/VEGF-A pathway. Targeting this pathway could potentially improve therapeutic outcomes of renal cell carcinoma.

We aimed to explore the relationship between hypoxia-inducible factors-1α (HIF-1α) and lncRNA nuclear-enriched abundant transcript 1 (NEAT1), and their functions on hepatocellular carcinoma (HCC) under hypoxia.

HIF-1α and NEAT1 levels in HCC tissues and corresponding non-tumor tissues were determined by qRT-PCR, and the correlations of their levels in HCC tissues were analyzed by Pearson test. The relationship between overall survival and the two genes (HIF-1α and NEAT1) for HCC patients was detected by log-rank test. Clinicopathological features of NEAT1 in HCC patients were collected. HIF-1α and NEAT1 levels in HCC cells were measured by qRT-PCR and Western blot, and their relationship was determined by co-immunoprecipitation (Co-IP) assay. Cell viability, migration and invasion were detected by CCK-8, scratch wound healing and transwell assay, respectively. The interaction of NEAT1 with HIF-1α in tumor development was determined by xenograft tumor assays in nude mice.

NEAT1 and HIF-1α were highly expressed and showed a positive relationship in HCC tissues, and specifically, higher NEAT1 expression was positively associated with advanced TNM stage and metastasis in HCC patients. Up-regulated NEAT1 or HIF-1α in HCC patients had poorer prognosis. NEAT1 was induced by HIF-1α and suppressed by siHIF-1α. NEAT1 overexpression further promoted development of HCC under hypoxia while promoting cell viability, migration and invasion and suppressing apoptosis, and such effects were reversed by down-regulating HIF-1α. NEAT1 overexpression promoted tumor growth, which was reversed by down-regulating HIF-1α.

HIF-1α knockdown inhibits NEAT1 expression, which suppresses progression of HCC and improves its prognosis.

Our study is the first one to evaluate the role of NSUN5 in the progression of colorectal cancer. Data from TCGA was used to show the different expression of NSUN5 between CRC tumor tissues and adjacent normal ones. The NSUN5 expression in the tissue microarray was detected by immunohistochemistry (IHC). qRT-PCR was conducted for NSUN5 expression examination in CRC cell lines. Cell proliferation was analyzed by the Celigo machine. Lorlatinib GESA and correlation analysis were performed to reveal the possible underlying mechanism. The effects of NSUN5 expression on CRC cell behavior in vitro were analyzed by flow cytometry and β-galactosidase staining. The expression of cell-cycle related proteins were evaluated by western blot. Subcutaneously implanted tumor model was carried out for animal experiment. NSUN5 expression was up-regulated in CRC tumor tissues and cells, and associated with advanced tumor stages (III, IV). NSUN5 could promote cell proliferation, trigger cell cycle arrest in vitro and boost tumor growth in vivo. In addition, knockdown of NSUN5 could lead to a higher expression of Rb and a lower expression of CDK4, CDK6, p-Rb and CCNE1, but made no difference on P21, Bcl-2, caspase3 and C-Caspase3 of CRC cells. Taken together, we identify NSUN5 as a promoter in CRC development via cell cycle regulation.Laryngeal carcinoma is one of the common malignancies of head and neck. However, the pathogenesis of laryngeal cancer has been not completely clear. To identify the effects of hypoxia on the invasion, metastasis, and metabolism of laryngeal carcinoma, iTRAQ-labeling-with-LC-MS/MS analysis was performed to identify differentially expressed proteins of the SCC10A cells under hypoxia and normoxia, while metabolites were examined by metabolic profiling. 155 proteins and 180 metabolites were identified and the PCK2 protein was selected for validation by Western Blotting. Immunohistochemistry (IHC) was performed to analyze the expression of PCK2 in formalin-fixed paraffin-embedded (FFPE) tissue sections, including laryngeal squamous cell carcinoma tissues from various stages. Collectively, we report that down-regulation of PCK2 inhibits the invasion, migration, and proliferation of laryngeal cancer under hypoxia and down-regulation of PCK2 may be used as a new strategy for laryngeal cancer therapy.Inositol-1,4,5-triphosphate-receptor 1 (IP3R1), a Ca2+ channel in the sarcoplasmic reticulum membrane, is an effective regulator of Ca2+ release involved in the pathology of most cardiovascular diseases. Our study aim to investigate the underlying mechanism by which IP3R1 signaling mediates the process of homocysteine (Hcy)-induced Ca2+ accumulation via interaction with sodium current (Nav1.5) in atrium. We utilized whole-cell patch-clamp analysis and flow cytometry to detect the abnormal electrical activity in mouse atrial myocytes (MACs) obtained from C57B6 mice fed with high-Hcy diet. The results represented not only an increase in protein levels of Nav1.5 and IP3R1, but also an enhanced intracellular levels of Ca2+, and prolonged action potential duration (APD). However, the inhibition of IP3R1 or Nav1.5 gene could both attenuate Ca2+ accumulation in MACs triggered by Hcy, as well as abnormal electrical activity. In addition, Hcy increased the interaction between IP3R1 and Nav1.5. These data suggest that Hcy induced Ca2+ accumulation is mediated by the IP3R1/Nav1.
