MIR183: MIR183, a type of microRNA, was investigated in a study comparing its levels in the serum of mice with ototoxicity to levels in the cochlea and kidney using qRT-PCR [PMC6163699]. The study aimed to understand the role of MIR183 in ototoxicity and its potential as a biomarker [PMC6163699]. Additionally, MIR183 was found to be closely associated with lymph node metastasis in 54 sporadic MTCs [PMC8074316]. This suggests that MIR183 may play a role in the progression and metastasis of medullary thyroid carcinoma [PMC8074316]. The findings highlight the potential clinical significance of MIR183 as a biomarker for lymph node metastasis and its potential as a therapeutic target for medullary thyroid carcinoma [PMC8074316]. Further research is needed to elucidate the underlying mechanisms by which MIR183 contributes to these processes [PMC8074316]. The qRT-PCR analysis used in these studies provides quantitative data on microRNA expression levels, allowing for accurate comparisons between different tissues and conditions [PMC6163699]. Overall, these studies shed light on the involvement of MIR183 in ototoxicity and lymph node metastasis, providing valuable insights for future research and clinical applications [PMC6163699] [PMC8074316].
