Cohesin Gene Promoter Methylation in Patients with Acute Myeloid Leukemia.

Background: Aberrant gene promoter methylation is one of the hallmarks of Acute Myeloid Leukemia (AML). is an important gene, implicated in sister chromatids cohesion, DNA repair, the regulation of gene transcription, apoptosis and hematopoiesis.

Methods: In this study, we investigate the possible implication of promoter methylation in AML pathogenesis using a cohort of AML patients and a cohort of healthy individuals.

The Types and Frequencies of X Chromosome Abnormalities in Women with Reproductive Problems.

Introduction: X chromosome architecture and integrity are essential for normal ovarian function. Both numerical and structural X chromosome abnormalities play an important role in female infertility. This study aimed to determine the types and frequency of X chromosome aberrations detected in women referred for cytogenetic investigation due to reproductive problems.

A 46,XX Karyotype in Men with Infertility: Two New Cases and Review of the Literature.

46,XX male sex reversal syndrome is a rare genetic cause of male infertility. We report on two new cases of this syndrome in men presenting with hypogonadism and infertility. Cytogenetic and molecular analysis was performed in both patients.

Female Reproductive Ageing and Chromosomal Abnormalities in a Large Series of Women Undergoing IVF.

Chromosomal abnormalities are often detected in women with reproductive problems. This study aimed to investigate the presence and type of chromosomal aberrations in peripheral blood of women undergoing in vitro fertilization (IVF) and their possible association with advanced maternal age (AMA). A total of 1,837 women undergoing IVF between 2016 and 2019 were enrolled in the study.

Cytogenetic findings of ectopic endometriotic tissue in women with endometriosis and review of the literature.

Objective: To determine chromosome and gene alterations in ectopic endometrial (EM) tissue which may be implicated in the clinical course or the progression of endometriosis and to review the literature concerning the cytogenetic findings of women with endometriosis.

Study Design: 15 women who underwent laparoscopic endometriosis surgery at the Athens Genesis Clinic were enrolled in the study. Ectopic endometrial tissue was surgically removed and further analyzed by conventional and molecular cytogenetic techniques.
