Summary
MicroRNAs (miRs) are key regulators in gastric cancer development, acting as oncogenes or tumor suppressors. Dysregulation of miRs impacts gastric cancer incidence, diagnosis, and prognosis, offering therapeutic potential.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- Gastric carcinogenesis involves genetic and epigenetic alterations of key genes.
- Microribonucleic acids (miRs) are small non-coding RNAs regulating gene translation.
- miRs play crucial roles in cancer, including gastric cancer, with both oncogenic and tumor-suppressive functions.
Purpose of the Study:
- To review the mechanisms of known miRs in gastric cancer.
- To summarize recent studies on oncogenic, tumor suppressor, and controversially acting miRs.
- To discuss the clinical applications of miRs as biomarkers and therapeutic tools for gastric cancer.
Main Methods:
- Literature review of studies on microRNAs in gastric cancer.
- Analysis of differential miR expression in gastric cancer tissues.
- Synthesis of information on miR mechanisms, roles, and clinical potential.
Main Results:
- Numerous miRs are differentially expressed in gastric cancer tissues.
- Specific miRs (e.g., miR-21, miR-106a, miR-17) act as oncogenes.
- Other miRs (e.g., miR-101, miR-181, miR-449, miR-486, let-7a) function as tumor suppressors.
Conclusions:
- miR dysregulation is associated with gastric cancer incidence, early diagnosis, and prognosis.
- Understanding miR biology can elucidate gastric cancer pathogenesis.
- miRs hold promise for developing novel diagnostic and therapeutic strategies against gastric cancer.

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...

Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...
