Insights

MicroRNAs (miRNAs) regulate apoptosis, a key cell process in cancer. This review covers how miRNAs influence cancer drug resistance by targeting apoptosis-related genes.

Area of Science:

  • Molecular Biology
  • Oncology
  • Gene Regulation

Background:

  • MicroRNAs (miRNAs) are crucial regulators of cellular processes, frequently altered in cancer.
  • Apoptosis, or programmed cell death, is a critical target in cancer development and treatment.
  • miRNAs play dual roles in apoptosis, acting as either pro-apoptotic or anti-apoptotic factors.

Purpose of the Study:

  • To review the current understanding of microRNA involvement in regulating apoptosis.
  • To explore the mechanisms by which miRNAs modulate apoptosis in cancer.
  • To summarize evidence linking miRNAs to cancer drug resistance.

Main Methods:

  • Literature review of recent research on miRNAs and apoptosis.
  • Analysis of studies investigating miRNA targeting of apoptosis-related genes.
  • Synthesis of findings on miRNA-mediated cancer drug resistance.

Main Results:

  • Many miRNAs function as anti-apoptotic factors by downregulating pro-apoptotic genes.
  • Conversely, some miRNAs promote apoptosis by targeting anti-apoptotic genes.
  • Evidence indicates a significant role for miRNAs in the development of cancer drug resistance.

Conclusions:

  • MicroRNAs are integral to the regulation of apoptosis in cancer.
  • Understanding miRNA-mediated apoptosis is crucial for developing novel cancer therapies.
  • Targeting specific miRNAs may overcome or sensitize tumors to cancer drug 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...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
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.
