Breast cancer (BC) is one of the most common malignant tumors in women, and screening relevant genes and markers that are involved in BC tumor genesis and progression is of great value. We previously found that messenger RNA expression of ARHGAP9 was high in BC tissue, but it is unclear whether ARHGAP9 participates in the progression of human BC. In this study, we found that ARHGAP9 expression was correlated with poor patient survival, American Joint Committee on Cancer clinical staging, tumor size, and tumor differentiation...

Breast cancer (BC) is the leading cause of cancer mortality in women worldwide. It recently was proven that miRNAs play a critical role in BC development. The use of natural agents for control of cancer by modulating miRNAs is promising. Oleuropein is a natural polyphenolic agent with anti-neoplastic properties and is well tolerated by humans. This study was undertaken to determine the therapeutic effects of oleuropein through modulation of master oncomiRs (miR-21 and miR-155) in BC cells. The present study provides the first link between miRNA and oleuropein as a mechanism in BC...

Chronic hepatitis B virus (HBV) infection remains the most common risk factor for hepatocellular carcinoma (HCC). High HBV surface antigen (HBsAg) levels are highly correlated with hepatocarcinogenesis and HBV-associated HCC development. However, the role and detailed mechanisms associated with HBsAg in HCC development remain elusive. In this study, we designed specific single guide RNAs (sgRNAs) targeting the open reading frames, preS1/preS2/S, of the HBV genome and established HBsAg knockout HCC cell lines using the CRISPR/Cas9 system...

Nogo-B receptor (NgBR) is a type I receptor with a single transmembrane domain and specifically binds to ligand Nogo-B. A previous study demonstrated that NgBR was highly expressed in human breast invasive ductal carcinoma and promoted epithelial-mesenchymal transition in breast tumor cells. Our recent work found that NgBR expression was associated with a poor prognosis in human patients with hepatocellular carcinoma (HCC). Here, we elucidate that the increased expression of NgBR contributes toward the increased cell growth of human HCC cells both in vitro and in vivo...

Like other tumors, lung cancer must induce angiogenesis as it grows. Hypoxia-inducible factor 1α (HIF-1α) is the inducible subunit of the HIF-1 transcription factor that regulates genes involved in the response to hypoxia, some of which contributes to angiogenesis. Vascular endothelial growth factor (VEGF) is one of the genes upregulated by HIF-1 and is the primary cytokine in relation to angiogenesis. In this study we tested whether aberrant activation of hypoxia inducible factor-1α/vascular endothelial growth factor (HIF-1α/VEGF) pathway correlates with response to radiotherapy and examined the response of lung cancer cells to hypoxia in vitro...

Ovarian cancer (OC) renders its lethality to enhanced metastasis and late detection. A plethora of growth factors including Vascular Endothelial Growth Factor (VEGF) and Fibroblast Growth Factor (FGF) stimulated signaling pathways regulate the invasive/metastatic behavior of ovarian tumors contributing to its aggressiveness. Autocrine VEGF-functioning by virtue of upregulated VEGFR2 contributes to the invasiveness of OC cells by modulating the MMPs. Studies have highlighted the interaction between FGF and VEGF signaling pathways during angiogenesis...

Galactosemia type 2 is an autosomal recessive disorder characterized by the deficiency of galactokinase (GALK) enzyme due to missense mutations in GALK1 gene, which is associated with various manifestations such as hyper galactosemia and formation of cataracts. GALK enzyme catalyzes the adenosine triphosphate (ATP)-dependent phosphorylation of α-d-galactose to galactose-1-phosphate. We searched 4 different literature databases (Google Scholar, PubMed, PubMed Central, and Science Direct) and 3 gene-variant databases (Online Mendelian Inheritance in Man, Human Gene Mutation Database, and UniProt) to collect all the reported missense mutations associated with GALK deficiency...

3,6-Anhydro-l-galactose (l-AHG) is a bioactive sugar that is a major component of agarose. Recently, l-AHG was reported to have anti-melanogenic potential in human epidermal melanocytes (HEMs) and B16F10 melanoma cells; however, its underlying molecular mechanisms remain unknown. At noncytotoxic concentrations, l-AHG has been shown to inhibit alpha-melanocyte-stimulating hormone-induced melanin synthesis in various cell models, including HEMs, melan-a cells, and B16F10 cells. Although l-AHG did not inhibit tyrosinase activity in vitro, reverse transcription-polymerase chain reaction results demonstrated that the anti-melanogenic effect of l-AHG was mediated by transcriptional repression of melanogenesis-related genes, including tyrosinase, tyrosinase-related protein-1 (TRP-1), tyrosinase-related protein-2 (TRP-2), and microphthalmia-associated transcription factor (MITF) in HEMs...
