Mutation of miR-21 targets endogenous lipoprotein receptor-related protein 6 and nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease (NAFLD) is a chronic disorder characterized by hepatic fat accumulation and abnormal lipid metabolism. Although miR-21 has been implicated in nonalcoholic fatty liver disease, it is unknown whether miR-21 could function as a therapeutic target. Here, we perform transfection analysis of miR-21 mimic or control mimic to evaluate the effects of miR-21 expression levels on human HepG2 nonalcoholic fatty liver cells.

[Expression of cytokeratin 19 in the development and progression of oral squamous cell carcinoma].

Purpose: To investigate the expression of cytokeratin 19 (CK19) in various stages of oral squamous cell carcinoma (OSCC), and to explore the relation between CK19 and OSCC.

Methods: Forty-nine specimens including normal oral mucosa, epithelial hyperplasia, epithelial dysplasia, and oral squamous carcinoma were investigated. The expression of CK19 was detected by immunohistochemistry and Western blot.

Association of insulin resistance with breast, ovarian, endometrial and cervical cancers in non-diabetic women.

Hyperinsulinemia and insulin resistance were reported to play a crucial role in diabetes-cancer relationship. This study aimed to explore the associations between insulin resistance and several female cancers in a non-diabetic population. This cross-sectional study was conducted in 121,230 middle-aged and elderly non-diabetic women.

[A comparative assessment of mechanical property between lingual and labial archwires using three-dimension finite element method].

Purpose: The purpose of this study was to investigate the mechanical property of lingual and labial archwires by using finite element method.

Methods: A three-dimensional finite element model including three maxillary left incisors of the 0.022-inch Dentaurum Discovery labial and Ormco 7th Generation lingual brackets was constructed and threaded with corresponding labial and lingual archwires.

Zinc mediated hepatic stellate cell collagen synthesis reduction through TGF-β signaling pathway inhibition.

This study is to investigate the effect and underlying mechanism of Zinc (Zn) on hepatic stellate cell collagen synthesis. The proliferation and collagen synthesis ability of LX-2 cells were detected after adding Zn. The collagen synthesis related proteins of MMP-13 and TIMP1 along with TGF-β signaling pathway related proteins were detected by Western blot.

Effects of asiaticoside on human umbilical vein endothelial cell apoptosis induced by Aβ1-42.

This study is to investigate the potential role of asiaticoside (AS) in Aβ1-42-induced apoptosis on the human umbilical vein endothelial cell (HUVEC). HUVEC cells were divided into Aβ1-42 group (treated with 50 μM Aβ1-42), AS groups (treated with 50 μM Aβ1-42 and 10 mM, 1 mM, 0.1 mM or 0.

Fructopyrano-(1→4)-glucopyranose inhibits the proliferation of liver cancer cells and angiogenesis in a VEGF/VEGFR dependent manner.

Purpose: To investigate whether fructopyrano-(1→4)-glucopyranose (FG) inhibits the proliferation of liver cancer cells and angiogenesis in a vascular endothelial growth factor (VEGF)/vascular endothelial growth factor receptor (VEGFR) dependent manner.

Methods: Bel-7402, HepG2 and SMMC-7721 cells with high expression of VEGF and VEGFR were screened. Bel-7402 cells and human microvascular endothelial cells (HMEC) were treated with FG for 48 h.

miRNA-124 down-regulates SOX8 expression and suppresses cell proliferation in non-small cell lung cancer.

Non-small lung cell carcinoma (NSCLC) is a leading lethal disease and a global health burden. The function of the Sex determining region Y (SRY)-related high mobility group box (SOX) family gene in cancer has attracted the attention of more and more scientists recently, yet there are few reports regarding the role of SOX in NSCLC. Our study aimed to investigate the expression of SOX8, a protein belonging to the E group of the SOX family, as well as SOX9, in non-small cell lung cancer (NSCLC) and the relationship of gene expression to clinicopathological factors and prognosis in patients.

BRAF mutation as a potential marker to identify the proximal colon serrated polyps with malignant potential.

A large number of serrated polyps with malignant potential in the proximal colon were underestimated using currently available criteria mostly based on architectural and cytological features, contributing to proximal interval colorectal cancers. Recently, increasing evidences indicate that BRAF((V600E)) mutation is a specific molecular feature and driver of the serrated pathway, and proximal serrated polyps with BRAF((V600E)) mutation have a high risk of progression to malignancy. We proposed that immunohistochemical detection of BRAF((V600E)) using a BRAF((V600E)) mutation-specific antibody is a feasible technique for reproducibly identifying proximal serrated polyps with malignant potential in clinical practice, which may need more aggressive treatment and vigilant clinical monitoring.
