Summary
MicroRNAs (miRNAs) are small molecules that regulate gene expression and are crucial in cell functions. Aberrant miRNA profiles are linked to thyroid cancer development and progression, offering diagnostic and prognostic potential.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- MicroRNAs (miRNAs) are endogenous non-coding RNAs regulating gene translation.
- miRNAs are key mediators of cellular processes like differentiation, proliferation, and survival.
- Dysregulated miRNA expression is implicated in various diseases, including cancer.
Purpose of the Study:
- To summarize recent findings on aberrant miRNA expression in thyroid cancers (TCs).
- To review the role of specific miRNA profiles in different types of TCs (papillary, follicular, rare types).
- To discuss the diagnostic, therapeutic, and prognostic significance of miRNAs in TCs.
Main Methods:
- Review of genome-wide analyses identifying miRNA profiles in TCs.
- Compilation of data on up- and down-regulated miRNAs in various carcinogenesis stages.
- Synthesis of current knowledge on miRNA involvement in TC pathology.
Main Results:
- Specific miRNA expression profiles characterize different types of thyroid cancers.
- Aberrant miRNA expression correlates with cancer stages and patient prognosis.
- Identified miRNAs show potential as biomarkers for TC diagnosis and treatment.
Conclusions:
- miRNA expression patterns are significantly altered in thyroid cancers.
- Individual miRNAs and their profiles hold promise for improving TC diagnosis and prognosis.
- Further research into miRNA functions can guide novel therapeutic strategies for TCs.

01:22MicroRNAs
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...

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
