miR-452 promotes the development of gastric cancer via targeting EPB41L3

In this study, we found that miR-452 was highly expressed in both tumor tissue and gastric cancer cells, and could directly target the cancer suppressor gene EPB41L3 3′-UTR. miR-452 significantly promoted the proliferation, migration and the S-phase arrest of gastric cancer cells, but EPB41L3 as a downstream target gene of miR-452 reversed such promoting effect. While down-regulation of miR-452 expression significantly inhibited the malignant biological behavior of gastric cancer cells, but this inhibitory effect was reversed by EPB41L3 siRNA. In addition, miR-452 in the gastric cancer xenograft model in nude mice could down-regulated the expression level of EPB41L3 and promote the growth of transplanted tumor in nude mice. Taken together, this study reveals the role of miR-452 in gastric cancer via inhibiting the target gene EPB41L3, suggesting that miR-452 has the potential to become a new target for the diagnosis and treatment of gastric cancer.

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Authors: Matti B, Zargar-Shoshtari K Abstract Prostate cancer represents a significant health burden worldwide. The cancer incidence had substantially increased since the introduction of prostate specific antigen (PSA) in cancer screening. This had led to considerable debates among health professionals and epidemiologists, since PSA as a screening tool seemed to be far from perfect. In New Zealand, the controversy was quite prominent in the last three decades, with some advocating the benefits of screening, while others concerned regarding the risk of harms. With the absence of an organised screening programme and ...

CONCLUSION: This study found that childhood cancer survivors in New Zealand had a high prevalence of developmental dental abnormalities and it identified potential risk factors related to their cancer treatment. Inequitable access to oral rehabilitation for this patient group argues for a mechanism for consistent improved access to publicly funded dental care across district health boards in New Zealand.

Authors: Peng C, Cohen DJ Abstract INTRODUCTION: Esophageal squamous cancer remains an important cause of mortality worldwide with two new immunotherapy drugs recently approved for metastatic disease. AREAS COVERED: The authors review the epidemiology and genomics of esophageal squamous cell carcinoma. They also examine prior trials involving targeted agents under investigation as well immunotherapies that have been approved and novel combinations. EXPERT OPINION: Great advances have been made in characterizing the molecular changes in esophageal carcinoma. However, relatively few drugs have shown benefit i...
