Porcine bone marrow mesenchymal stem cells (pBMSCs) have the potential for application in regenerative medicine. This study aims to investigate the effects of extracellular calcium ([Ca(2+)]o) on pBMSCs proliferation and to explore the possible underlying mechanisms. The results demonstrated that 4 mM [Ca(2+)]o significantly promoted pBMSCs proliferation by reducing the G0/G1 phase cell percent...

INTRODUCTION Gestational trophoblastic disease (GTD) is a heterogeneous group of pregnancy-related disorders. Hydatidiform mole (HM) is the most common type of GTD, whereas gestational choriocarcinoma is the most aggressive. Non-receptor tyrosine kinase c-Src contributes to the transformation to a malignant phenotype in various cancers. However, the role of c-Src in the pathogenesis of GTD rema...

Primitive marrow lineage-negative rhodamine low and Hoechst low (LRH) stem cells isolated on the basis of quiescence respond to the cytokines thrombopoietin, FLT3L, and steel factor by synchronously progressing through cell cycle. We have now profiled the mRNA expression, as determined by real-time RT-PCR, of 47 hematopoietic or cell cycle-related genes, focusing on the variations in the cell c...

MicroRNAs (miRNAs) play important roles in the progression of human cancer. Although previous reports have shown that miR-145-5p is down-regulated in esophageal squamous cell carcinoma (ESCC), the roles and mechanisms of down-regulation of miR-145-5p in ESCC are still largely unknown. Using microRNA microarray and Gene Expression Omnibus (GEO) datasets, we confirmed that miR-145-5p was down-reg...

Tectonic family member 1 (TCTN1) is one of the tectonic family members, and a regulator of the hedgehog signaling pathway, which has been studied in various cancer types, including prostate and pancreatic cancer. However, its function in thyroid cancer has not been well documented. Therefore, the present study investigated the function of TCTN1 in thyroid cancer using a loss-of-function assay. ...

OBJECTIVE Patients over 60 years of age have higher mortality and morbidity after major liver resections. Nitric oxide (NO) derived from the catalytic activity of Nos2 plays a beneficial role in liver regeneration (LR) after partial hepatectomy (PH). In this experiment, we evaluated the effect of Nos2 knockout (KO) on LR in aged mice after PH. MATERIALS AND METHODS In this experimental study,...

Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a recently identified oncoprotein that is overexpressed in many human malignant tumors including cervical cancer. Human papillomavirus (HPV) oncoprotein E7 is the key transformation factor in cervical cancer. Our previous data showed a positive association of CIP2A and HPV-16E7 protein levels; however, how CIP2A is regulated by HPV-E7 and...
