    Dual role of thyroid hormones in rat soleus muscle MyHC isoform expression

  • Original language description

    We have analyzed the influence of altered thyroid hormone levels on changes of MyHC protein isoforms and their mRNA transcripts in the soleus muscle of 2-, 4- and 7-month-old euthyroid (EU), hypothyroid (TH) and hyperthyroid (HY) female inbred Lewis strain rats. We have found that the content of the dominant MyHC1 isoform gradually increased in the EU rats and this increase has been even more progressive in the HY rats at all three stages.Our results thus suggest that in the rat soleus muscles, both increased and decreased levels of thyroid hormones speed up the formation of an adult phenotype which is demonstrated by the precocious appearance of the slow MyHC1 isoform, but a longer T3 application of thyroid hormones promote the expression of the faster MyHC 2a isoform

    Dvojí úloha tyroidních hormonů v expresi MyHC isoformy m. soleus u potkana

  • Czech description

    Analyzovali jsme vliv změněné hladiny tyroidního hormonu na přepis MyHC izoforem proteinu a mRNA v m. soleus u 2, 4 a 7 měsíčních eutyroidních, hypotyroidních a hypertyroidních samičích inbredních potkanů kmene Lewis. Shledali jsme, že obsah dominantní MyHC1 izoformy u eutyroidních potkanů postupně vzrůstal. Tento vzestup byl dokonce mnohem výraznější u hypotyroidních potkanů ve všech třech stadiích. Naproti tomu u hypertyroidních jedinců došlo k rychlému nárůstu u 2 měsíčních následovaném poklesem MyHC1 u starších potkanů
