Summary
Circular RNAs and miRNAs form novel regulatory axes impacting Krüppel-like factor 4 (KLF4) in cancer. These RNA interactions offer new therapeutic targets for various malignancies.
Area of Science:
- Epigenetics
- Molecular Biology
- Oncology
Background:
- Krüppel-like factor 4 (KLF4) is epigenetically regulated and implicated in cell reprogramming and cancer.
- KLF4 expression correlates with tumor invasiveness and prognosis in a tissue-specific manner.
- KLF4 plays a role in diverse and prevalent human cancers.
Purpose of the Study:
- To investigate the interplay between circular RNAs (circRNAs), microRNAs (miRNAs), and KLF4 in cancer.
- To elucidate the regulatory mechanisms involving circRNA/miRNA/KLF4 axes.
Main Methods:
- Literature search on PubMed using keywords 'miRNA and KLF4 and cancer' (last 5 years) and 'circRNA and KLF4' (2013-2024).
- Selection of relevant oncological publications.
Main Results:
- Identification of circRNA/miRNA axes that regulate KLF4 expression.
- circRNAs function as miRNA sponges, influencing KLF4 activity.
- KLF4 exhibits context-dependent roles as a tumor promoter or suppressor.
Conclusions:
- circRNA/miRNA/KLF4 axes represent a novel layer of epigenetic regulation in cancer.
- These RNA-based modulators explain KLF4's complex regulation.
- This axis presents potential for new therapeutic strategies targeting cancer.

01:22MicroRNAs
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...

02:39lncRNA - Long Non-coding RNAs
8.9K
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...

03:03mTOR Signaling and Cancer Progression
3.9K
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.

02:23Master 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...

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...

02:33Combinatorial Gene Control
8.4K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
