Deeply Saddening Life Events Play a Carcinogenic Role by Inducing Mutations in and Genes.

Background/objectives: In the past few decades, many studies have been conducted to find out that psychological stress and cancer are closely linked. Moreover, it was reported that stress can induce mutations in gene level. Therefore, in this study we want to examine a relationship between stressful life events, gene mutation and cancer.

Investigation of diabetes-related molecular changes in embryo-endometrium crosstalk.

The primary aim of this study was to explore the impact of diabetes on matrix metalloproteases and tissue inhibitors, crucial factors for successful implantation, and to elucidate the molecular mechanisms that undergo changes in the endometrium and the embryo during diabetic pregnancies. In this investigation, we established a streptozotocin-induced diabetic pregnant rat model. Microarray analysis followed by RT-PCR was utilized to identify gene regions exhibiting expression alterations.

Growth suppression by MYC inhibition in small cell lung cancer cells with TP53 and RB1 inactivation.

Small cell lung cancer (SCLC) is the most aggressive type of lung cancer with high mortality. One of the MYC family genes, MYC, MYCL or MYCN, is amplified in ~20% of the SCLCs; therefore, MYC proteins are potential therapeutic targets in SCLC patients. We investigated the therapeutic impact of Omomyc, a MYC dominant negative, in a panel of SCLC cell lines.
