Summary
MicroRNA-182-5p (miR-182) is upregulated in prostate cancer, promoting disease progression and epithelial-to-mesenchymal transition (EMT) by targeting MITF. This suggests miR-182 as a potential biomarker for prostate cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Altered microRNA-182-5p (miR-182) expression is linked to various cancers.
- The specific role of miR-182 in prostate cancer, particularly its involvement in epithelial-to-mesenchymal transition (EMT), is not well understood.
Purpose of the Study:
- To profile miR-182 expression in prostate cancer.
- To investigate the contribution of miR-182 to prostate cancer progression and EMT.
Main Methods:
- In vitro experiments using prostate cancer cell lines.
- In silico analyses of The Cancer Genome Atlas (TCGA) prostate adenocarcinoma (PRAD) datasets.
- Polymerase chain reaction (PCR) for gene expression analysis.
- Bioinformatic and functional enrichment analyses.
Main Results:
- PCR confirmed significantly increased miR-182 expression in prostate cancer cells versus normal cells.
- TCGA data analysis revealed miR-182 upregulation associated with prostate cancer and disease progression markers.
- Functional enrichment analysis linked miR-182 and its targets to EMT.
- Melanocyte inducing transcription factor (MITF) was identified as a novel target of miR-182.
Conclusions:
- This study is the first to report that miR-182 overexpression in prostate cancer contributes to EMT by targeting MITF.
- miR-182 may serve as a valuable diagnostic and prognostic biomarker for prostate cancer and other malignancies.

03:03mTOR Signaling and Cancer Progression
3.8K
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.

02:38Mitogens 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...

02:23Abnormal Proliferation
4.6K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

02:23Master 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...

3.8K
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...

3.1K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
