Summary
Circular RNAs (circRNAs) like hsa_circ_0000467 are upregulated in gastric cancer, promoting tumor growth and invasion by interacting with miR-326-3p. This circRNA shows potential as a diagnostic marker and therapeutic target for gastric cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Circular RNAs (circRNAs) are critical regulators of gene expression.
- Their specific roles in gastric cancer pathogenesis remain incompletely understood.
- Gastric cancer is a significant global health concern requiring novel diagnostic and therapeutic strategies.
Purpose of the Study:
- To investigate the expression and function of hsa_circ_0000467 in gastric cancer.
- To elucidate the molecular mechanism underlying hsa_circ_0000467's role in gastric cancer progression.
- To assess the potential of hsa_circ_0000467 as a diagnostic biomarker and therapeutic target.
Main Methods:
- Quantitative real-time PCR (qRT-PCR) to measure hsa_circ_0000467 expression in tissues and cell lines.
- Cell proliferation and invasion assays (e.g., Transwell assays).
- Dual-luciferase reporter assays to confirm direct interaction between hsa_circ_0000467 and miR-326-3p.
Main Results:
- hsa_circ_0000467 was significantly upregulated in gastric cancer tissues and cell lines compared to controls.
- hsa_circ_0000467 expression correlated with histological grade.
- Downregulation of hsa_circ_0000467 inhibited cell proliferation, invasion, and G2/M phase transition.
- hsa_circ_0000467 directly targets miR-326-3p, and miR-326-3p inhibition reversed the effects of hsa_circ_0000467 downregulation.
Conclusions:
- hsa_circ_0000467 promotes gastric cancer development and progression by sponging miR-326-3p.
- hsa_circ_0000467 represents a potential diagnostic biomarker and therapeutic target for gastric cancer.

3.6K
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...

7.2K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

9.6K
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...

6.0K
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.

5.0K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
