Feedback Regulation of Calcium Concentration

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 Signaling

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,...

Non-Canonical Wnt Signaling Pathways

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...

Fertilization

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...

Summary

This summary is machine-generated.

The initial calcium signal during fertilization is a crucial, well-understood event that triggers embryonic development. This foundational calcium signaling provides insights into later developmental processes and cell cycle control.

Area of Science:

Developmental Biology
Cell Signaling
Reproductive Biology

Background:

Embryonic development initiation relies on significant calcium transients.
Fertilization-induced calcium signals are the most studied aspect of developmental calcium signaling.
Understanding these initial signals informs research on later embryonic calcium events.

Purpose of the Study:

To elucidate the mechanisms and properties of the fertilization calcium transient.
To identify downstream targets of the fertilization calcium signal.
To establish the role of calcium signals in early embryonic cell cycles and mitosis.

Main Methods:

Analysis of calcium-releasing second messengers.
Investigation of calcium-signaling mechanisms, including propagating waves.
Examination of cell cycle resumption and progression post-fertilization.

Main Results:

The fertilization calcium signal involves diverse known calcium-releasing messengers and signaling pathways.
These signals often manifest as propagating calcium waves.
Fertilization calcium signals are directly linked to cell cycle resumption and control of mitosis.

Conclusions:

The fertilization calcium transient is a fundamental trigger for embryonic development.
Its well-characterized mechanisms serve as a model for understanding subsequent developmental calcium signals.
Calcium signaling is integral to early embryonic cell cycle progression and development.
