Insights

Long non-coding RNAs (lncRNAs) regulate cancer therapy resistance by controlling autophagy, a key cellular process. Understanding lncRNA-autophagy interactions may reveal new therapeutic targets for overcoming chemoresistance and radioresistance.

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Cellular Biology

Background:

  • Autophagy, a lysosomal degradation pathway, is regulated by autophagy-related genes (ATGs) and is implicated in cancer development.
  • Cancer therapies like chemotherapy and radiotherapy improve survival but are often limited by therapy resistance, leading to poor patient prognosis.
  • Long non-coding RNAs (lncRNAs) are emerging as critical regulators of cellular processes, including autophagy.

Purpose of the Study:

  • To systematically review and elucidate the role of lncRNAs in mediating chemoresistance and radioresistance in cancer through the regulation of autophagy.
  • To explore the mechanisms by which lncRNAs influence autophagy-related signaling pathways, such as the PI3K/AKT/mTOR pathway, in the context of cancer therapy resistance.

Main Methods:

  • Literature review of studies investigating the relationship between lncRNAs, autophagy, and cancer therapy resistance.
  • Analysis of research on lncRNA regulation of autophagy-related genes (ATGs) and signaling pathways.
  • Synthesis of findings on the impact of lncRNAs on chemoresistance and radioresistance.

Main Results:

  • lncRNAs are identified as crucial regulators that modulate autophagy by affecting ATGs and key signaling pathways like PI3K/AKT/mTOR.
  • Dysregulation of lncRNA-mediated autophagy significantly contributes to the development of chemoresistance and radioresistance in various cancer types.
  • Specific lncRNAs have been shown to either promote or inhibit autophagy, thereby influencing the efficacy of cancer treatments.

Conclusions:

  • lncRNAs play a pivotal role in cancer chemoresistance and radioresistance by fine-tuning the autophagy pathway.
  • Targeting lncRNA-autophagy interactions presents a promising strategy for developing novel therapeutic approaches to overcome cancer therapy resistance.
  • Further investigation into the precise mechanisms of lncRNA regulation of autophagy could identify new autophagy-related therapeutic targets for cancer treatment.

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...

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.

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,...

Types of RNA01:20

Types of RNA

Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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...
