Letrozole Decreased Testosterone-Induced Cell Proliferation and Prolactin Secretion also Increased Apoptosis in MMQ and GH3 Rat Prolactinoma Cell Lines.

Aromatase enzyme plays an essential role in estrogen-induced tumorigenesis. It is expressed in the normal pituitary and more significantly in prolactinoma tissues. The aim of this study was to investigate the effects of an aromatase inhibitor, letrozole, on MMQ and GH3 rat prolactinoma cell lines and evaluate the possible mechanism of action.

Determination of antibiotic susceptibility of bacteria by flow cytometric method.

In this study, it was aimed to determine the antibiotic susceptibility of bacterial strains by using flow cytometry method by comparing them with current standardized methods. Eleven clinical isolates and 6 standard bacterial strains were included in the study. MIC values were determined by broth microdilution method (BMD), VITEK 2® automated system and flow cytometric method (FCM).

The effect of mesenchymal stromal cells ın the microenvironment on cancer development.

Inflammatory signals secreted from the tumor microenvironment are thought to promote tumor growth and survival. It has been reported that stromal cells in the tumor microenvironment have similar characteristics to tumor-associated cells. In addition miRNAs play critical roles in various diseases, including cancer.

Protective role of melatonin against testicular damage caused by polymicrobial sepsis in adult rats.

Background: This study aimed to investigate the possible protective effects of melatonin (MEL) against the damage to testicular tissue in rats caused by polymicrobial sepsis as a result of cecal ligation and perforation (CLP).

Methods: In this study, 21 male Wistar albino rats were used. The rats were randomly divided into three groups (n=7): Sham Control (Group 1), CLP (Group 2), and CLP + MEL (Group 3).

Age-related changes in the immunomodulatory effects of human dental pulp derived mesenchymal stem cells on the CD4 T cell subsets.

Mesenchymal stem cells (MSCs) are powerful immunomodulatory cells. The effects of the aging on these abilities of MSCs have not been adequately clarified. In this study, alterations in immunomodulatory abilities of MSCs caused by aging were investigated.
