Insights

Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) form an axis regulating cancer. This lncRNA-miRNA axis impacts tumor growth, metastasis, and therapy resistance, offering diagnostic and prognostic potential.

Area of Science:

  • Molecular Biology
  • Genetics
  • Cancer Research

Background:

  • Epigenetic factors are crucial in biological processes and disease, particularly cancer.
  • Long non-coding RNAs (lncRNAs) function as epigenetic regulators in cancer initiation and progression.
  • MicroRNAs (miRNAs) are key downstream targets of lncRNAs, forming critical regulatory axes.

Purpose of the Study:

  • To review the role of the lncRNA-miRNA axis in cancer malignancy.
  • To explore the implications of the lncRNA-miRNA axis in tumor therapy resistance.
  • To highlight the diagnostic and prognostic potential of the lncRNA-miRNA axis in cancer.

Main Methods:

  • Literature review of studies on lncRNA-miRNA interactions in cancer.
  • Analysis of lncRNA-miRNA roles in cancer cell death (apoptosis, autophagy).
  • Investigation of lncRNA-miRNA influence on tumor metastasis (EMT, MMPs) and therapy sensitivity.

Main Results:

  • The lncRNA-miRNA axis regulates apoptosis, autophagy, epithelial-mesenchymal transition (EMT), and matrix metalloproteinases (MMPs).
  • This axis influences sensitivity to chemotherapy, radiotherapy, and immunotherapy.
  • lncRNAs can be modulated by therapeutic interventions, affecting downstream miRNAs and cancer progression.
  • The lncRNA-miRNA axis interacts with signaling pathways like PI3K/Akt, STAT3, and Wnt/β-catenin.

Conclusions:

  • The lncRNA-miRNA axis is a significant regulator of cancer development, metastasis, and therapy resistance.
  • Dysregulation of the lncRNA-miRNA axis contributes to various hallmarks of cancer.
  • The lncRNA-miRNA axis holds promise as a biomarker for cancer diagnosis and prognosis.

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...

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...

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...

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
