PURPOSE To conduct a systematic review of prospective studies assessing the association of vitamin D intake or blood levels of 25-hydroxyvitamin D [25(OH)D] with the risk of colorectal cancer using meta-analysis. METHODS Relevant studies were identified by a search of MEDLINE and EMBASE databases before October 2010 with no restrictions. We included(More)
Leucine-rich repeat kinase 2 (LRRK2) has been identified by genome-wide association studies as being encoded by a major susceptibility gene for Crohn's disease. Here we found that LRRK2 deficiency conferred enhanced susceptibility to experimental colitis in mice. Mechanistic studies showed that LRRK2 was a potent negative regulator of the transcription(More)
BACKGROUND & AIMS Overexpression of cyclooxygenase-2 (COX-2) is implicated in many steps of cancer development. Single nucleotide polymorphisms (SNPs) in the COX-2 promoter might contribute to differential COX-2 expression and subsequent interindividual variability in susceptibility to cancer. This study sought to identify functional SNPs in the COX-2(More)
BACKGROUND Zonulin is a newly discovered protein that has an important role in the regulation of intestinal permeability. Our previous study showed that probiotics can decrease the rate of infectious complications in patients undergoing colectomy for colorectal cancer. OBJECTIVE The objective was to determine the effects of the perioperative(More)
LncRNA SPRY4-IT1 has been shown to promote the progression of melanoma. However, the role of lncRNA SPRY4-IT1 in human esophageal squamous cell carcinoma (ESCC) remains unclear. The purpose of this study is to investigate the clinical significance and biological functions of SPRY4-IT1 in ESCC. The expression levels of lncRNA SPRY4-IT in 92 ESCC patients and(More)
BACKGROUND Colorectal liver metastases (CLM) occur frequently and postoperative intestinal infection is a common complication. Our previous study showed that probiotics could decrease the rate of infectious complications after colectomy for colorectal cancer. To determine the effects of the perioperative administration of probiotics on serum zonulin levels(More)
PURPOSE Human papillomavirus (HPV) infection plays an important role in the development of cervical cancer, but the prevalence of HPV infection in women of Shenzhen city remains unclear. The present study was performed to describe the change of cervical HPV infection in females who participated in voluntary cervical cancer screening from 2006 to 2010 in(More)
Autophagy plays a central role in regulating important cellular functions such as cell survival during starvation and control of infectious pathogens. Recently, it has been shown that autophagy can induce cells to die; however, the mechanism of the autophagic cell death program is unclear. We now show that caspase inhibition leading to cell death by means(More)
BACKGROUND Emerging evidence suggests that single nucleotide polymorphisms (SNPs) in microRNA-coding genes may participate in the pathogenesis of lung cancer by altering the expression of tumor-related microRNAs. Several studies were investigated in recent years to evaluate the association between hsa-miR-196a2 rs11614913 polymorphism and(More)
Recently, microRNAs have emerged as regulators of cancer metastasis through acting on multiple signaling pathways involved in metastasis. In this study, we have analyzed the level of miR-10b and cell motility and invasiveness in several human esophageal squamous cell carcinoma cell lines. Our results reveal a significant correlation of miR-10b level with(More)
