Oogenesis02:07

Oogenesis

58.0K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Cushing Syndrome II: Pathophysiology

21
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

2.4K
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Hormonal Control of the Ovarian Cycle

5.1K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle.  At puberty, GnRH secretion increases in both frequency and...

Pharmacogenomics: Identification of New Drug Targets

119
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

81
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Summary

Cocaine- and amphetamine-regulated transcript (CART) levels are lower in women with polycystic ovary syndrome (PCOS). Lower CART may offer protection against PCOS development.

Area of Science:

  • Endocrinology
  • Neuroendocrinology
  • Reproductive Biology

Background:

  • Cocaine- and amphetamine-regulated transcript (CART) is an anorectic neuropeptide involved in food intake, endocrine function, and ovarian modulation.
  • Polycystic ovary syndrome (PCOS) is a common endocrinological disorder affecting women of reproductive age, characterized by multiple ovarian cysts.

Purpose of the Study:

  • To investigate the association between CART peptide levels and PCOS.
  • To explore the relationship between CART, metabolic parameters, and hormonal profiles in women with and without PCOS.

Main Methods:

  • A case-control study involving 148 participants (73 with PCOS, 75 controls).
  • Measurement of fasting blood glucose, insulin, lipids, hs-CRP, reproductive hormones, free testosterone, and CART levels.
  • Calculation of HOMA-IR and BMI; correlation and logistic regression analyses were performed.

Main Results:

  • CART levels were significantly lower in women with PCOS compared to controls (90.77 ± 5.98 pg/ml vs. 93.24 ± 8.17 pg/ml, p=0.038).
  • CART showed negative correlations with BMI and waist circumference in both groups.
  • In controls, CART positively correlated with insulin and HOMA-IR, and negatively with FBG.
  • Logistic regression suggested a potential protective effect of CART against PCOS (OR: 0.94, 95% CI=0.888-0.997, p=0.038).

Conclusions:

  • CART peptide levels are reduced in women with PCOS.
  • CART may play a role in the pathophysiology of PCOS and potentially exert a protective effect.
