Summary
This summary is machine-generated.MicroRNA-377 (miR-377) inhibits prostate cancer (PCa) by targeting the MYC gene. This study shows miR-377 suppresses MYC, reducing tumor growth and promoting apoptosis in PCa cells.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Prostate cancer (PCa) frequently overexpresses the proto-oncogene MYC.
- Aberrant microRNA (miRNA) expression is implicated in PCa development and progression.
Purpose Of The Study
- To investigate the regulatory role of miR-377 on MYC in prostate cancer.
- To evaluate the functional consequences of miR-377-mediated MYC suppression on PCa cell behavior.
Main Methods
- Luciferase assays to confirm direct targeting of MYC mRNA by miR-377.
- Real-time PCR to quantify MYC, BCL-2, Bax, PTEN, and CDK4 mRNA levels.
- Analysis of apoptosis, proliferation, cell cycle, and migration in transfected PCa cell lines.
Main Results
- miR-377 directly targets and downregulates MYC mRNA and protein levels.
- MYC suppression by miR-377 led to decreased BCL-2 and CDK4, and increased Bax and PTEN expression.
- Overexpression of miR-377 induced apoptosis, inhibited proliferation and migration, and caused cell cycle arrest in PCa cells.
Conclusions
- miR-377 acts as a tumor suppressor in prostate cancer by inhibiting MYC.
- miR-377 demonstrates potential as a therapeutic target for prostate cancer treatment.

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...
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...
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.
The mTOR pathway or the...
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

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...
