Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

3.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

7.5K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

2.2K
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...

Ovarian Cycle01:27

Ovarian Cycle

5.0K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

7.5K
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...

Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

4.2K
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Summary
This summary is machine-generated.

Luteal angiogenesis, the formation of new blood vessels, is crucial for corpus luteum function and requires a balance of stimulatory and inhibitory factors. Understanding these regulators, including FGF2 and VEGFA, aids in managing ovarian activity.

  • Endocrinology

Background:

  • Angiogenesis is vital for corpus luteum (CL) structure and function, supporting its high metabolic rate.
  • Rapid luteal vascular regression is necessary for the ovarian cycle's continuation in the absence of pregnancy.
  • Luteal angiogenesis is a complex, tightly regulated process involving numerous factors.

Purpose of the Study:

  • To review key endogenous factors regulating luteal angiogenesis.

Main Methods:

  • Review of existing literature on luteal angiogenesis.
  • Analysis of in vitro luteal angiogenesis cultures.
  • Examination of the roles of fibroblast growth factor 2 (FGF2) and vascular endothelial growth factor A (VEGFA).

Main Results:

  • Fibroblast growth factor 2 (FGF2) is critical for endothelial cell proliferation and sprouting in luteal angiogenesis.
  • Vascular endothelial growth factor A (VEGFA) and platelet-derived growth factor are important modulators of luteal angiogenesis.
  • Small non-coding microRNAs likely play a significant role in post-transcriptional regulation of luteal angiogenesis.
