Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

3.5K
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...

Calmodulin-dependent Signaling

5.3K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

Fertilization01:38

Fertilization

72.7K
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

Summary

Artificial oocyte activation, using calcium ionophore, helps overcome fertilization failure in vitro fertilization. This treatment is crucial for patients with sperm-related oocyte activation deficiency.

Area of Science:

  • Reproductive biology
  • Assisted reproductive technology

Background:

  • In vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) can experience fertilization failure.
  • Defective calcium-mediated cell signaling in oocytes can lead to failed fertilization.
  • Sperm-related oocyte activation deficiency is a specific cause of fertilization issues.

Purpose of the Study:

  • To investigate the role of artificial oocyte activation (AOA) in overcoming fertilization failure.
  • To highlight AOA as a treatment for specific patient subgroups.

Main Methods:

  • Utilizing calcium ionophore for artificial oocyte activation.
  • Application as an add-on treatment in IVF/ICSI cycles.

Main Results:

  • AOA effectively addresses recurrent or total fertilization failure.
  • It corrects defective physiological processes related to fertilization signaling.
  • AOA is particularly beneficial for patients with sperm-related oocyte activation deficiency.

Conclusions:

  • Artificial oocyte activation is a valuable intervention for select patients.
  • It is not routinely recommended but essential for specific cases of fertilization deficiency.
  • AOA targets critical calcium-mediated signaling pathways for successful fertilization.
