Insights

Clinically evident lung cancers accumulate genetic and epigenetic abnormalities in oncogenes and tumor suppressor genes. Understanding these molecular changes, the "hallmarks of lung cancer," offers new targets for detection, prevention, and treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Lung cancer development involves numerous genetic and epigenetic alterations.
  • These molecular changes affect key cellular functions, leading to cancer progression.

Purpose of the Study:

  • To review recent advancements in understanding the molecular biology of lung cancer.
  • To highlight genetic abnormalities in tumor suppressor genes and oncogenes.
  • To identify the "hallmarks of lung cancer" as potential therapeutic targets.

Main Methods:

  • Review of current scientific literature on lung cancer molecular biology.
  • Focus on genetic alterations, including tumor suppressor gene inactivation and oncogene overactivity.

Main Results:

  • Clinically evident lung cancers exhibit a multitude of genetic and epigenetic abnormalities.
  • These alterations result in specific "hallmarks of lung cancer" that drive disease progression.

Conclusions:

  • The identified "hallmarks of lung cancer" represent promising targets for novel therapeutic strategies.
  • Further research into these molecular hallmarks can advance early detection, prevention, and treatment of lung cancer.

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 (lncRNA)...
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...
Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
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 specific...
