Elevated Mtss1 Expression Associated With Metastasis And Poor Prognosis Of Residual Hepatitis B-Related Hepatocellular Carcinoma, Xiu-Yan Huang, Zi-Li Huang, Bin Xu, Zi Chen

Dartmouth Scholarship

Background: Hepatectomy generally offers the best chance of long-term survival for patients with hepatocellular carcinoma (HCC). Many studies have shown that hepatectomy accelerates tumor metastasis, but the mechanism remains unclear.

Methods: An orthotopic nude mice model with palliative HCC hepatectomy was performed in this study. Metastasis-related genes in tumor following resection were screened; HCC invasion, metastasis, and some molecular alterations were examined in vivo and in vitro. Clinical significance of key gene mRNA expression was also analyzed.

Let-7 Microrna-Binding-Site Polymorphism In The 3′Utr Of Kras And Colorectal Cancer Outcome: A Systematic Review And Meta-Analysis, Scott M. Langevin, Brock C. Christensen

Dartmouth Scholarship

There is a small but growing body of literature regarding the predictive utility of a Let-7 microRNA-binding-site polymorphism in the 30 -untranslated region (UTR) of KRAS (KRAS-LCS6) for colorectal cancer outcome, although the results are conflicting. We performed a review and meta-analysis in an attempt to better clarify this relationship. A PubMed search was conducted to identify all studies reporting on KRAS let-7 microRNA-binding site polymorphism (LCS6; rs61764370) and colorectal cancer outcome. Hazard ratios (HR) and corresponding 95% confidence intervals (CI) were extracted or estimated from each manuscript. Log HRs and log CIs were combined across studies using the inverse-variance …
