In addition, the specific correlation of other tumor-related key molecules in HT and PTC has also been reported: compared with normal thyroid tissues or other thyroiditis tissues, in HT and PTC tissues, CD98 (involved in the transport of amino acids on the cell surface) was significantly lower expressed (32), p63 specifically expressed (33) and hOGG1 gene specifically deleted. The gene discussed is OGG1; the disease is thyroiditis.
