Summary
Long non-coding RNAs (lncRNAs) are key in cancer. This study shows LINC01420 is upregulated in thyroid cancer, inhibiting cell proliferation and progression, suggesting it as a therapeutic target.
Area of Science:
- Genomics
- Molecular Biology
- Oncology
Background:
- The human genome extensively transcribes non-coding RNAs, including long non-coding RNAs (lncRNAs).
- lncRNAs are implicated in various cancer progressions.
- The specific roles of lncRNAs in thyroid cancer (TC) remain largely unknown.
Purpose of the Study:
- To investigate the expression and function of LINC01420 in thyroid cancer.
- To explore the potential of LINC01420 as a diagnostic or therapeutic target in TC.
Main Methods:
- Comparative analysis of LINC01420 expression in TC tissues versus normal thyroid tissues.
- Bioinformatics analysis to predict LINC01420's molecular functions.
- Loss-of-function assays (e.g., knockdown) to assess LINC01420's impact on TC cell behavior.
Main Results:
- LINC01420 was found to be upregulated in thyroid cancer tissues.
- Bioinformatics analysis linked LINC01420 to critical cellular processes like translation, RNA processing, and DNA repair.
- Knockdown of LINC01420 significantly inhibited thyroid cancer cell proliferation and cell cycle progression.
Conclusions:
- LINC01420 plays a regulatory role in thyroid cancer development.
- LINC01420 may serve as a potential therapeutic target for thyroid cancer.
- Elevated LINC01420 expression levels show promise as a prognostic marker for TC.

9.7K
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...

13.0K
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...

5.8K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

3.7K
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...
