Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

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 Signaling01:16

Calmodulin-dependent Signaling

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

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...
Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...
Gonadal and Placental Hormones01:24

Gonadal and Placental Hormones

The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...

Summary
This summary is machine-generated.

Calcium signaling is crucial for fetal development and placental function. Disruptions in calcium homeostasis are linked to pregnancy complications like pre-eclampsia and intrauterine growth restriction.

Area of Science:

  • Reproductive biology
  • Cellular signaling
  • Maternal-fetal medicine

Background:

  • The placenta is vital for fetal development, facilitating nutrient, gas, and waste exchange.
  • Calcium ions (Ca2+) are essential for skeletal development and act as critical second messengers.
  • Significant amounts of Ca2+ are actively transported across the placenta during human pregnancy.

Purpose of the Study:

  • To review the role and implications of Ca2+ signaling in reproduction, with a focus on placentation.
  • To highlight the importance of intracellular Ca2+ concentration for oocyte fertilization, blastocyst implantation, and placental development.
  • To discuss the limited understanding of placental Ca2+ regulation proteins and their function in pathologies.

Main Methods:

  • Literature review of existing studies on Ca2+ signaling in reproduction and placentation.
  • Analysis of current knowledge regarding Ca2+ homeostasis in normal and pathological pregnancies.
  • Identification of proteins involved in placental Ca2+ regulation.

Main Results:

  • Ca2+ waves are critical for oocyte fertilization.
  • Intracellular Ca2+ concentration is fundamental for blastocyst implantation and placental function.
  • Alterations in Ca2+ homeostasis are observed in placental pathologies such as pre-eclampsia and intrauterine growth restriction.

Conclusions:

  • A comprehensive understanding of Ca2+ signaling in human reproduction is essential.
  • Further research into Ca2+ regulation proteins may provide insights into impaired pregnancy outcomes.
  • Investigating Ca2+ homeostasis disruptions could lead to improved management of placental pathologies.
