Insights

Non-coding RNAs (ncRNAs) play a dual role in gastric cancer (GC) by regulating autophagy. Understanding ncRNA-autophagy interactions offers potential therapeutic strategies for GC patients.

Area of Science:

  • Molecular Biology
  • Oncology
  • Cellular Biology

Background:

  • Autophagy is a fundamental cellular process involved in degrading damaged components.
  • Autophagy significantly influences gastric cancer (GC) progression, including tumorigenesis, metastasis, and drug resistance.
  • Non-coding RNAs (ncRNAs) are key regulators of biological processes, including autophagy, and exhibit dual roles in GC as oncogenes or tumor suppressors.

Purpose of the Study:

  • To review the role of autophagy in gastric cancer.
  • To explore the regulatory mechanisms of ncRNAs in autophagy.
  • To elucidate the dual role of ncRNA-modulated autophagy in GC for therapeutic development.

Main Methods:

  • Literature review of studies on autophagy, ncRNAs, and gastric cancer.
  • Analysis of existing evidence on ncRNA regulation of autophagy in GC.
  • Synthesis of findings on the dual functions of ncRNAs in GC-associated autophagy.

Main Results:

  • ncRNAs can either promote or inhibit GC progression by modulating autophagy.
  • Autophagy modulation by ncRNAs impacts GC cell malignant transformation and drug resistance.
  • The precise dependency of ncRNA function on autophagy in GC remains an area for further investigation.

Conclusions:

  • ncRNA-mediated autophagy plays a critical role in gastric cancer.
  • Targeting ncRNA-autophagy pathways presents a promising therapeutic avenue for GC.
  • Further research into ncRNA targets within autophagy pathways is crucial for developing novel GC treatments.

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.
The mTOR pathway or the...

Autophagy01:27

Autophagy

Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

lncRNA - Long Non-coding RNAs

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...

Delivery Pathways to the Lysosome

Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

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...

Regulation of Expression at Multiple Steps01:23

Regulation of Expression at Multiple Steps

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...
