Summary
Recombinant human thyroid-stimulating hormone (rhTSH) offers clinical benefits in thyroid cancer follow-up, avoiding hypothyroidism. It also shows promise in treating benign thyroid diseases and diagnosing congenital hypothyroidism.
Area of Science:
- Endocrinology
- Oncology
- Nuclear Medicine
Background:
- Recombinant human thyroid-stimulating hormone (rhTSH) is an established alternative to thyroid hormone withdrawal for thyroid cancer patient follow-up.
- rhTSH avoids hypothyroidism and associated quality of life impacts, as well as potential tumor growth stimulation from prolonged TSH elevation.
Purpose of the Study:
- To review established and emerging clinical applications of rhTSH.
- To highlight rhTSH's benefits in thyroid cancer management, benign thyroid conditions, and congenital hypothyroidism diagnosis.
Main Methods:
- Review of clinical benefits and applications of rhTSH.
- Analysis of rhTSH's role in thyroid cancer follow-up, benign thyroid disease treatment, PET scanning enhancement, chemotherapy, and congenital hypothyroidism diagnosis.
Main Results:
- rhTSH is a safe and effective alternative to thyroid hormone withdrawal for thyroid cancer follow-up.
- In benign thyroid diseases, rhTSH improves tracer uptake and allows for reduced 131I dosage while maintaining efficacy.
- rhTSH enhances FDG-PET detectability of metastases and shows promise in improving chemotherapy response rates for poorly differentiated thyroid cancers.
Conclusions:
- rhTSH provides significant clinical advantages in thyroid cancer management by preventing hypothyroidism.
- Emerging applications demonstrate rhTSH's utility in benign thyroid diseases, diagnostic imaging, and chemotherapy, as well as in the differential diagnosis of congenital hypothyroidism.

01:20The Central Dogma
The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

02:53Conservative Site-specific Recombination and Phase Variation
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

01:29Issues And Trends In Healthcare Delivery System
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

02:50Transgenic Plants
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
