Immunoexpression of progesterone receptor, epithelial growth factor receptor and galectin-3 in uterine smooth muscle tumors.

Uterine smooth muscle tumors constitute a spectrum of neoplasms. Diagnosis of leiomyomas (LMs) is usually straight forwards; however, atypical leiomyomas (ALMs) and smooth muscle tumors of uncertain malignant potential (STUMPs) have overlapping features and need to be distinguished from leiomyosarcoma. To evaluate progesterone receptor (PR), epithelial growth factor receptor (EGF-R), and galectin-3 expression in LMs, ALMs, STUMPs, and leiomyosarcomas and to assess their possible role in differentiating those tumors.

Correlation between serum leptin and its gene expression to the anthropometric measures in overweight and obese children.

Obesity is a multifactor disorder with evidence supporting the role of the genetic factor in its etiology. The present study evaluates the relationship between leptin G2548A (rs7799039) and leptin receptors (Gln223Arg (rs1137101) genotyping and its leptin level and the risk of childhood obesity. This case-control study was conducted on 168 overweight and obese Saudi children and 126 non obese one served as control.
