Summary
This summary is machine-generated.Activating transcription factor 1 (ATF1) promotes cervical cancer progression by repressing miR-630, which targets MAL2. ATF1 may be a therapeutic target for cervical malignancies.
Area Of Science
- Oncology
- Molecular Biology
- Biochemistry
Background
- Activating transcription factor 1 (ATF1) is implicated in cervical cancer development, but its precise role and regulatory mechanisms remain unclear.
- Understanding the molecular pathways governing cervical cancer progression is crucial for identifying novel therapeutic targets.
Purpose Of The Study
- To elucidate the role of ATF1 in cervical cancer.
- To investigate the regulatory relationship between ATF1, miR-630, and MAL2 in cervical carcinoma.
- To explore the potential of ATF1 as a clinical marker and therapeutic target.
Main Methods
- Quantitative reverse transcription polymerase chain reaction (qRT-PCR), immunohistochemistry, and Western blot assays were used to assess ATF1, miR-630, and MAL2 expression.
- Cellular assays including colony formation, Transwell migration, and invasion assays were performed to evaluate the impact of ATF1 and miR-630 on cervical carcinoma cell behavior.
- Chromatin immunoprecipitation (ChIP), RNA immunoprecipitation (RIP), and dual luciferase reporter assays were employed to confirm molecular interactions.
Main Results
- Elevated ATF1 expression and decreased miR-630 expression were observed in cervical cancer tissues, with a negative correlation between them.
- Inhibition of ATF1 suppressed cervical carcinoma cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT).
- Upregulation of miR-630 counteracted the aggressive phenotypes of cervical carcinoma cells, targeting MAL2 for repression.
- ATF1 was confirmed to directly transcriptionally repress miR-630, establishing a regulatory axis.
Conclusions
- ATF1 modulates the miR-630/MAL2 pathway, significantly influencing EMT and the aggressive behavior of cervical carcinoma cells.
- The findings suggest that ATF1 plays a critical role in cervical cancer progression.
- ATF1 represents a potential biomarker and therapeutic target for interventions in cervical malignancies.

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...
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...
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...
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
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...
