Cancer stem cells (CSCs) are responsible for the unrestrained cell growth and chemo-resistance of malignant tumors. Reports about miR-33a in different type of cancer are limited, and it remains elusive whether there is a link between miR-33a and chemo-resistance of CSCs. Here we report that Lgr5+ hepatocellular carcinoma (HCC) cells from primary tissues and cell lines behave similarly to CSCs and are chemo-resistant to doxorubicin. Significantly, reduced miR-33a expression is associated with the chemo-resistance of Lgr5+ HCC-CSCs, accompanied by an overexpression of ABCA1 which is identified as target of miR-33a by mainly using miRNA luciferase assay and western-blotting...

Orphan nuclear receptor TLX has been shown to play an essential role in regulating the self-renewal and proliferation of neural stem cells (NSCs). However, TLX overexpression in NSCs induces long-term NSC expansion and further leads to glioma initiation in mouse when combined with p53 mutations. Whether overexpression of TLX plays a role in glioma stem cell (GSC) proliferation and migration still remains largely unknown. In this study, we infected C6 cells, a special glioma cell line which is mainly composed of cancer stem cells(CSCs), with lentiviruses expressing GFP(LV-GFP) or GFP-T2A-TLX(LV-TLX) and then monitored cell proliferation and migration using the real-time analyzer system (RTCA, xCELLigence, Roche)...

Hepatocellular carcinoma (HCC) is the third leading cause of cancer associated mortality. Accumulating evidence has shown that microRNAs (miRNAs) act as critical factors for tumor recurrence and metastasis. MiR-508-5p has been reported as a down-regulated miRNA in the primary gastric cancer tissues. However, the role of miR-508-5p on HCC has not been well elucidated. In this study, we observed that miR-508-5p was downregulated in HCC tissues when compared to the non-tumorous tissues. We then demonstrated that overexpression of miR-508-5p attenuated HepG2 cells proliferation and invasion and induced cell apoptosis in vitro...

G protein-coupled receptor 56 (GPR56) has been demonstrated to be a significant prognostic predictor in several types of malignances, including melanoma, glioblastoma, breast cancer, colon cancer, and pancreatic cancer. GPR56 has a putative mucin-like extracellular domain, indicating functions for this receptor in the cell-cell interactions and triggering different downstream signaling pathways responsible for regulating cell survival, proliferation, adhesion, and migration. But the expression and clinical significance of GPR56 has not been elucidated in epithelial ovarian cancer (EOC)...

We report in this study that microRNA-584-3p (miR-584-3p) is related to the vasculogenic mimicry (VM) of human glioma cells. Unsurprisingly, the postoperative survival time was significantly prolonged in those glioma patients without VM phenomena compared with those with positive VM. miR-584-3p may function as a potent tumor suppressor by inhibiting VM of malignant glioma. However, the molecular mechanisms underlying these properties remain poorly understood. Our preliminary mechanistic studies revealed that miR-584-3p suppressed the VM by disturbing hypoxia-induced stress fiber formation and migration of glioma cells...

The link between sunlight and skin cancer is a frequently discussed topic. However, ultraviolet radiation also induces the production of Vitamin D in the body. Keratinocytes and their ability to synthesize the active form of Vitamin D, which is consumed at the place of its origin in the skin, have a unique place in this discussion. We observe a remarkable sunshine-related paradox when we monitor the relationship between the dose of solar radiation and one type of skin cancer - malignant melanoma. Recent knowledge of the non-calcemic effects of Vitamin D, which include growth regulation, DNA repair, differentiation, apoptosis, membrane transport, metabolism, cell adhesion and oxidative stress, could help to further clarify this relationship...
