Summary
MicroRNAs regulate gene expression and are vital biomarkers for thyroid cancer (TC) detection. Alterations in miRNA biogenesis genes, like DGCR8 mutations, are linked to TC development and progression.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) are key regulators of gene expression, influencing crucial cellular processes like proliferation and survival.
- Dysregulated miRNAs are implicated in various cancers, serving as potential blood-based biomarkers for early detection and prognosis.
- The miRNA biogenesis pathway is essential for thyroid gland development and function.
Purpose of the Study:
- To review the role of microRNAs in thyroid cancer (TC).
- To explore novel findings regarding miRNA dysregulation in TC.
- To summarize the current understanding of microRNAs in thyroid carcinomas.
Main Methods:
- Literature review of scientific publications.
- Analysis of studies on miRNA biogenesis in thyroid cancer.
- Focus on mutations in microprocessor component genes, specifically DGCR8.
Main Results:
- Alterations in miRNA biogenesis genes are frequently observed in TC.
- Mutations in microprocessor components, such as the recurrent DGCR8 E518K mutation, are associated with increased TC risk.
- miRNA dysregulation is a significant factor in thyroid carcinogenesis.
Conclusions:
- MicroRNAs play a critical role in thyroid cancer development and progression.
- Investigating miRNA alterations offers promising avenues for diagnostic and prognostic tools in TC.
- Further research into miRNA biogenesis and its role in TC is warranted.

01:22MicroRNAs
3.0K
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...

01:20The Retinoblastoma Gene
4.1K
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.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

02:23Abnormal Proliferation
4.5K
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...

02:39lncRNA - Long Non-coding RNAs
8.6K
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...

02:38Mitogens and the Cell Cycle
6.5K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

02:55The Nucleolus
8.8K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
