Insights

Long non-coding RNAs (lncRNAs) significantly contribute to chemotherapy drug resistance in various cancers. Understanding lncRNA mechanisms offers potential for novel cancer treatment strategies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Chemotherapy is a cornerstone of cancer treatment, but drug resistance frequently leads to treatment failure.
  • Mechanisms of chemoresistance are complex, involving factors like drug efflux, DNA repair, apoptosis, and target mutations.
  • Long non-coding RNAs (lncRNAs) are increasingly recognized for their regulatory roles in biological processes.

Purpose of the Study:

  • To review the mechanisms by which lncRNAs mediate chemoresistance in various cancers.
  • To explore the therapeutic potential of targeting lncRNAs for overcoming drug resistance in cancer treatment.

Main Methods:

  • This review synthesizes current research on lncRNAs and their involvement in cancer drug resistance.
  • Literature search focused on studies investigating lncRNA function in breast, gastric, and lung cancers, among others.
  • Analysis of reported mechanisms including lncRNA-mediated regulation of drug efflux, DNA repair, apoptosis, and target mutations.

Main Results:

  • lncRNAs play crucial roles in the development of chemoresistance across multiple cancer types.
  • Dysregulation of specific lncRNAs can affect various cellular pathways, leading to reduced sensitivity to chemotherapeutic agents.
  • lncRNAs have been implicated in resistance through mechanisms such as modulating drug targets and affecting DNA damage response.

Conclusions:

  • lncRNAs are key regulators of chemotherapy resistance in cancer.
  • Targeting lncRNAs presents a promising therapeutic strategy to enhance the efficacy of chemotherapy and overcome drug resistance.

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...

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...

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...

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.
