Summary
MicroRNAs (miRNAs) regulate gene expression by binding to messenger RNAs. This review explores how miRNAs impact lysophosphatidic acid signaling, influencing processes like cell growth and cancer.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- MicroRNAs (miRNAs) are key regulators of gene expression, influencing cellular processes.
- Aberrant miRNA function is implicated in malignant cell development, acting as tumor suppressors or oncogenes.
- Lysophosphatidic acid (LPA) signaling pathways are crucial in various cellular functions and are implicated in cancer.
Purpose of the Study:
- To review the current understanding of miRNA regulation within the context of lysophosphatidic acid (LPA) signaling.
- To highlight specific miRNAs that modulate LPA receptors and downstream signaling proteins.
- To discuss the potential of RNA-based therapeutics in precision medicine.
Main Methods:
- Literature review of studies investigating miRNA and LPA signaling.
- Analysis of identified miRNAs that are upregulated or downregulated by LPA stimulation.
- Examination of miRNAs that target LPA receptors or associated signaling proteins.
Main Results:
- Several miRNAs, including miR-21, miR-30c-2-3p, and miR-122, increase in response to LPA stimulation.
- Other miRNAs, such as miR-15b, miR-23a, miR-200c, miR-146, and miR-21, inhibit LPA receptors or downstream signaling.
- The complex interplay between miRNAs and LPA signaling is still under active investigation.
Conclusions:
- miRNAs play a significant role in modulating lysophosphatidic acid signaling pathways.
- Understanding these interactions is crucial for deciphering their role in both normal physiology and disease, particularly cancer.
- The emerging field of RNA-based therapeutics holds promise for targeted treatments in precision medicine.

01:22PI3K/mTOR/AKT Signaling Pathway
5.4K
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...

01:01Autocrine Signaling
52.1K
Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.

03:03mTOR Signaling and Cancer Progression
4.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:20The JAK-STAT Signaling Pathway
12.2K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

01:07MAPK Signaling Cascades
8.0K
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...

01:28Gene Regulation in Microbial Communities: Quorum Sensing
537
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...
