Summary
This summary is machine-generated.MicroRNA-25-3p is upregulated in colorectal cancer (CRC), promoting tumor growth and metastasis. Inhibiting miR-25-3p suppressed proliferation and enhanced apoptosis, identifying it as a potential therapeutic target for CRC.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- MicroRNA (miRNA) dysregulation is linked to human cancers, including colorectal cancer (CRC).
- Understanding the specific roles of miRNAs in CRC development is crucial for targeted therapies.
Purpose Of The Study
- To investigate the role of miR-25-3p in colorectal cancer progression.
- To identify miR-25-3p as a potential therapeutic target and prognostic biomarker for CRC.
Main Methods
- Analysis of microarray data (GSE183437, GSE156719) to identify candidate miRNAs.
- Reverse transcription-quantitative PCR to verify miR-25-3p expression.
- In vitro assays using HCT116 and Caco-2 cells to assess miR-25-3p's functional impact.
- Investigation of the regulatory relationship between miR-25-3p and FBXW7.
Main Results
- miR-25-3p was significantly upregulated in CRC tissues and cell lines.
- Elevated miR-25-3p expression correlated with advanced tumor stage, metastasis, and poorer survival.
- Downregulation of miR-25-3p inhibited cell proliferation and induced apoptosis in CRC cells.
- FBXW7 was identified as a direct target of miR-25-3p, with an inverse expression correlation.
Conclusions
- miR-25-3p acts as an oncogenic miRNA in colorectal cancer.
- Targeting miR-25-3p may offer a novel therapeutic strategy for CRC.
- miR-25-3p serves as a potential prognostic indicator for colorectal cancer patients.

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...
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).

The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...
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...
