AI Article Synopsis

  • Breast cancer is a complex disease primarily affecting women, with one significant risk factor being genetic changes, particularly in the CYP19A1 gene, which influences estrogen production in tumors.
  • A systematic review was conducted to explore how varying levels of CYP19A1 gene expression impact breast cancer outcomes, analyzing studies published between 2009 and 2019.
  • Out of over 6,000 studies reviewed, six were selected that linked CYP19A1 expression levels to critical factors like disease aggressiveness and patient survival rates.

Article Abstract

Breast cancer is the most frequently diagnosed malignant neoplasm in women and is considered a multifactorial disease of unknown etiology. One of the major risk factors is genetic alteration. Changes in CYP19A1 gene expression levels have been associated with increased risk and increased aggressiveness of breast cancer. Increased CYP19A1 gene expression and/or aromatase activity are among the major regulatory events for intratumoral production of estrogens in breast malignant tissues. This systematic review aimed to investigate the influence of CYP19A1 gene expression levels in women with breast cancer. The research was carried out using the PubMed, Scopus, and Web of Science databases. Searches were conducted between February 2 and May 15, 2019. Inclusion criteria were studies published between 2009 and 2019, English language publications, and human studies addressing the gene expression of CYP19A1 in breast cancer. A total of 6.068 studies were identified through PubMed (n=773), Scopus (n=2,927), and the Web of Science (n=2,368). After selecting and applying the inclusion and exclusion criteria, six articles were included in this systematic review. This systematic review provides evidence that increased or decreased levels of CYP19A1 gene expression may be related to pathological clinical factors of disease, MFS, OS, DFS, WATi, markers of metabolic function, concentrations of E1, FSH, and in the use of multiple exons 1 of the CYP19A1 gene in breast cancer.

Characterizing how organisms respond to transient temperatures may further our understanding of their susceptibility to climate change. Past studies in the freshwater turtle, , have demonstrated that the timing and duration of heat waves can have major implications for the response of genes involved in gonadal development and the production of female hatchlings. Yet, no study has considered how the response of these genes to transient cold snap exposure may affect gonadal development and the production of males.

We hypothesized that human chorionic gonadotropic (hCG) could replace LH in the maturation media for buffalo oocytes, and hCG administration before ovum pick-up (OPU) enhances in-vitro development of buffalo oocytes. Objectives were 1) to investigate the effect of hCG supplementation on nuclear maturation, oocyte development, and granulosa cell mRNA abundance of genes related to growth and antioxidant pathways and 2) to determine the effect of hCG administration before OPU on in-vitro oocyte development. In Experiment 1, buffalo oocytes retrieved from slaughterhouse ovaries were maturated in the media supplemented with 0.

The most frequent type of leukemia in Africa is chronic myeloid leukemia (CML). The genetic background of the rarer Philadelphia chromosome (Ph) Ph-ve (BCR-ABL-ve) subform of CML is largely unknown in African patients. Therefore, in this study, we aimed to investigate the role of CYP1A1 and 2D6 SNPs in the pathogenesis of Ph-ve CML in the Sudanese population.

Scabiosa artropurperea, a member of the Dipsacaceae family and Scabiosa genus, is renowned for its medicinal properties. In the present study, we investigated the impact of Scabiosa artropurperea aqueous extract (AES) on the in vivo reproductive functions in Queue Fine de l'Ouest ewes, and on in vitro ovine granulosa cells. Ewes were synchronized for 14 days with intra-vagina progesterone (P4) devices (FGA, 20 mg) and divided into four groups receiving daily oral doses of 0, 1, 2, and 4 mg of AES/kg Live Body Weight (LBW), respectively.

Article Synopsis
  • Aromatase deficiency is a rare genetic disorder caused by mutations in the CYP19A1 gene, affecting both males and females, with an incidence of less than 1 in 1,000,000.
  • In females, symptoms typically present at birth or in early infancy, focusing on sexual development, while in males, issues usually emerge during or after puberty, leading to delayed diagnosis.
  • The paper reviews the skeletal and extraskeletal effects of the condition and discusses strategies for managing bone health in individuals with these mutations.
