Summary
Glycogen synthase kinase-3 (GSK-3) regulates Wnt signaling and cellular processes. Its role in cancer highlights the need for GSK-3 inhibitors, as it influences microRNAs and cell fate.
Area of Science:
- Biochemistry
- Molecular Biology
- Cancer Biology
Background:
- Glycogen synthase kinase-3 (GSK-3) is a key regulator of beta-catenin signaling (Wnt signaling).
- Dysregulation of Wnt signaling and beta-catenin is implicated in numerous human cancers.
- GSK-3's precise role remains under investigation, driving research into targeted inhibitors.
Purpose of the Study:
- To review the regulation of GSK-3, focusing on its interplay with Wnt signaling.
- To highlight GSK-3's interactions with microRNAs (miRNAs) involved in pluripotency and epithelial-mesenchymal transition (EMT).
- To establish GSK-3 as a critical kinase in cellular process regulation.
Main Methods:
- Literature review of GSK-3 regulation.
- Analysis of GSK-3's role in Wnt signaling pathways.
- Examination of GSK-3's interaction with miRNAs relevant to cancer.
Main Results:
- GSK-3 influences the Wnt signaling destruction complex, affecting beta-catenin stability.
- GSK-3 regulates miRNAs associated with pluripotency and EMT, processes crucial in cancer development.
- Evidence suggests GSK-3's role in kinase-mediated transcriptional regulation in cancers.
Conclusions:
- GSK-3 is a pivotal kinase in cellular regulation, impacting Wnt signaling and miRNA expression.
- GSK-3 acts as a potential master regulator of proteins and noncoding RNAs, influencing cell fate.
- Targeting GSK-3 may offer therapeutic strategies for various cancers.

13.1K
Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.

6.3K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

5.4K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

8.5K
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze...

8.3K
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒ small G-proteins consisting of a single domain and large multi-domain G-proteins.

3.5K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...
