Insights

Drug resistance in cancer is a major hurdle. Non-coding RNAs (ncRNAs) regulate ferroptosis, a cell death pathway, offering new strategies to overcome chemotherapy resistance by targeting the ncRNA-ferroptosis axis.

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Chemotherapy resistance is a significant obstacle in cancer treatment, leading to poor patient outcomes.
  • Ferroptosis, a distinct form of regulated cell death, shows promise in suppressing tumor progression and overcoming drug resistance.
  • Non-coding RNAs (ncRNAs) are increasingly recognized for their role in regulating cancer cell sensitivity to ferroptosis through epigenetic modifications.

Purpose of the Study:

  • To review the role of chemotherapeutic resistance in cancer.
  • To summarize the molecular mechanisms of ferroptosis and its epigenetic regulation by ncRNAs.
  • To highlight the ncRNA-ferroptosis axis as a potential therapeutic target for overcoming drug resistance.

Main Methods:

  • Literature review of studies on ferroptosis, ncRNAs, and cancer drug resistance.
  • Analysis of epigenetic regulatory mechanisms involving ncRNAs in ferroptosis.
  • Synthesis of current understanding of how ncRNAs modulate ferroptosis to impact chemotherapeutic resistance.

Main Results:

  • Chemotherapeutic resistance contributes to cancer development and progression.
  • Ferroptosis is a critical cell death pathway influenced by epigenetic modifications, particularly by ncRNAs.
  • ncRNAs play a crucial role in regulating cancer cell ferroptosis, thereby affecting sensitivity to chemotherapy.

Conclusions:

  • The ncRNA-ferroptosis axis represents a promising therapeutic strategy for overcoming chemotherapeutic resistance.
  • Understanding ncRNA-mediated epigenetic regulation of ferroptosis is key to developing novel cancer treatments.
  • Targeting the interplay between ncRNAs and ferroptosis offers a new avenue for enhancing cancer therapy efficacy.

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...

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

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...

Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Types of RNA01:23

Types of RNA

Overview
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 the regulation of 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.
