Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

7.0K
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,...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

7.9K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

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...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

3.0K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Diversity in Cell Signaling Responses01:22

Diversity in Cell Signaling Responses

8.4K
The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity. 
Graded and Abrupt Responses
Some signaling systems generate...

Molecular Factors Affecting Cell Division01:27

Molecular Factors Affecting Cell Division

4.1K
Several external and internal factors influence the initiation and inhibition of cell division. For instance, the death of nearby cells or the release of human growth hormone (hGH) promotes cell division. In contrast, lack of hGH or crowding of cells can inhibit cell division.
Several proteins function as internal regulators to ensure each cell cycle stage is completed faithfully before proceeding to the next. Regulator molecules may act directly or influence the activity or production of other...

Area of Science:

  • Cell Biology
  • Biophysics
  • Biochemistry

Background:

  • Intracellular calcium ions (Ca(2+)) are crucial signaling molecules in cellular processes.
  • Disruptions in Ca(2+) homeostasis, caused by stressors like magnetic fields (MF), can lead to cell dysfunction or death.
  • The precise effects and mechanisms of MF on cells, especially concerning Ca(2+) signaling, remain under investigation.

Purpose of the Study:

  • To investigate the correlation between intracellular calcium ion concentration and cell viability.
  • To review mechanisms regulating intracellular Ca(2+) in non-excitable cells under stress, such as MF exposure.
  • To synthesize current knowledge on how MF influences Ca(2+) homeostasis and signaling pathways.

Main Methods:

  • Review of existing literature on intracellular Ca(2+) regulation and detection techniques.
  • Analysis of studies examining the impact of MF on Ca(2+) fluxes and homeostasis.
  • Focus on Ca(2+) regulatory mechanisms in non-excitable cell models (e.g., U937, HeLa).

Main Results:

  • Calcium ions act as essential intracellular second messengers, mediating cellular responses to various stimuli.
  • MF exposure is a potential stressor that can perturb Ca(2+) homeostasis and signaling.
  • Existing physical models propose mechanisms for MF-induced ionic transport disturbances, but experimental validation is ongoing.

Conclusions:

  • Understanding Ca(2+) regulation is vital for elucidating cellular responses to environmental factors like MF.
  • Further research is needed to clarify the dual nature (positive/negative) and underlying mechanisms of MF effects on cells.
  • This review highlights the importance of studying Ca(2+) dynamics in non-excitable cells for understanding stress responses.
