Identification of new reference genes with stable expression patterns for cell cycle experiments in human leukemia cell lines.

Cell cycle-dependent gene expression analysis is particularly important as numerous genes show tightly regulated expression patterns at different phases of the cell cycle. For cancer cells, analysis of cell cycle-related events is of paramount significance since tumorigenesis is characteristically coupled to cell cycle perturbations. RT-qPCR is a highly sensitive technique to investigate cell cycle-dependent transcriptional regulation.

Estrogen-regulated lateral septal kisspeptin neurons abundantly project to GnRH neurons and the hypothalamic supramammillary nucleus.

While hypothalamic kisspeptin (KP) neurons play well-established roles in the estrogen-dependent regulation of reproduction, little is known about extrahypothalamic KP-producing (KP) neurons of the lateral septum. As established previously, expression in this region is low and regulated by estrogen receptor- and GABA receptor-dependent mechanisms. Our present experiments on knock-in mice revealed that transgene expression in the LS begins at P33-36 in females and P40-45 in males and is stimulated by estrogen receptor signaling.

Three-Dimensional Speckle-Tracking Echocardiography-Derived Tricuspid Annular Properties in Acromegaly-Results from the MAGYAR-Path Study.

Introduction: Acromegaly is an endocrine pathology characterized by the overproduction of human growth hormone. The present study aimed to analyze three-dimensional speckle-tracking echocardiography (3DSTE)-derived tricuspid annular (TA) properties in detail in patients with acromegaly and to compare the findings to those of matched healthy controls.

Methods: The present study consisted of 29 patients with acromegaly (mean age: 55.

Right ventricular longitudinal shortening and right atrial volumes are not associated in healthy adults-detailed analysis from the three-dimensional speckle-tracking echocardiographic MAGYAR-Healthy Study.

Background: There is a close relationship between volumes of the right atrium (RA) and dimensions and derived functional sphincter-like features of the tricuspid annulus (TA). However, its relation to longitudinal TA motion is not clear, which can even be considered to be a characteristic of the longitudinal shortening of the right ventricle (RV) and represented by TA plane systolic excursion (TAPSE). Therefore, the aim of this cohort study was to perform a detailed analysis of the relationship of three-dimensional speckle-tracking echocardiography (3DSTE)-derived RA volumes and RV longitudinal shortening in healthy individuals.
