Insights

Nuclear factor (erythroid-derived 2)-like 2 (NRF2) regulates antioxidant genes and influences cancer chemotherapy resistance. NRF2 also controls microRNAs (miRNAs), impacting tumor development and treatment outcomes.

Area of Science:

  • Molecular Biology
  • Oncology
  • Gene Regulation

Background:

  • Nuclear factor (erythroid-derived 2)-like 2 (NRF2) is a master regulator of cellular defense against oxidative stress.
  • Dysregulation of the NRF2 pathway is implicated in cancer development and resistance to chemotherapy.
  • MicroRNAs (miRNAs) are small non-coding RNAs that play critical roles in gene expression and cancer pathogenesis.

Purpose of the Study:

  • To review the regulatory role of NRF2 in microRNA (miRNA) expression.
  • To explore the functional significance of NRF2-regulated miRNAs in tumorigenesis.
  • To examine the impact of NRF2-miRNA interactions on cancer chemotherapy resistance.

Main Methods:

  • Literature review of studies investigating NRF2, miRNAs, and cancer.
  • Analysis of evidence linking NRF2 signaling to miRNA expression patterns.
  • Synthesis of findings on the role of NRF2-miRNA axis in cancer biology.

Main Results:

  • NRF2 directly regulates the expression of numerous miRNAs.
  • Aberrantly expressed miRNAs controlled by NRF2 can function as oncogenes or tumor suppressors.
  • The NRF2-miRNA network is a significant factor in cancer progression and therapeutic response.

Conclusions:

  • NRF2-mediated regulation of miRNAs is a crucial mechanism in cancer.
  • Targeting the NRF2-miRNA axis may offer novel therapeutic strategies for malignancies.
  • Understanding this interplay is vital for overcoming chemotherapy resistance.

MicroRNAs01:22

MicroRNAs

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...

Abnormal Proliferation02:23

Abnormal Proliferation

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 daughter...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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.

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

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...
