Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

1.7K
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

6.6K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

7.6K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

Master Transcription Regulators02:23

Master Transcription Regulators

7.0K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Microbial Growth Media01:27

Microbial Growth Media

233
Microbial growth media are essential tools in microbiology, providing the nutrients and conditions necessary to cultivate and study microorganisms. These media are categorized by their composition, consistency, and functional roles, enabling researchers to investigate microbial physiology, behavior, and interactions.Types and Consistencies of Growth MediaGrowth media can be solid, liquid, or semisolid. Solid media, often agar-based, allow visible colony growth for isolation and enumeration.

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

2.1K
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...

Summary

Growth differentiation factor 15 (GDF15) regulates appetite and body weight, impacting conditions like anorexia and pregnancy sickness. Recent research highlights its independent roles in energy expenditure and insulin sensitivity, suggesting new therapeutic avenues.

Area of Science:

  • Endocrinology
  • Metabolic Research
  • Molecular Biology

Background:

  • Growth differentiation factor 15 (GDF15) is a stress-induced cytokine implicated in appetite regulation and metabolic disorders.
  • GFRAL and RET were identified as the specific receptor and co-receptor for GDF15, primarily in the hindbrain.
  • GDF15 influences anorexia-cachexia syndromes and pregnancy-related nausea and vomiting.

Purpose of the Study:

  • To review current literature on GDF15 biology.
  • To update the understanding of GDF15's role in metabolic health and disease.
  • To explore the therapeutic potential of GDF15.

Main Methods:

  • Literature review of recent scientific publications.
  • Analysis of GDF15's known functions and receptor interactions.
  • Synthesis of findings related to GDF15's impact on energy balance and insulin sensitivity.

Main Results:

  • GDF15 plays a key role in appetite suppression and body weight regulation.
  • Emerging evidence indicates GDF15 independently affects energy expenditure and insulin sensitivity.
  • GDF15's receptor, GFRAL, and co-receptor, RET, are localized to specific hindbrain regions.

Conclusions:

  • GDF15 is a significant regulator of energy homeostasis.
  • Beyond appetite suppression, GDF15 influences energy expenditure and insulin sensitivity.
  • GDF15 presents potential therapeutic targets for metabolic diseases and related conditions.
