This study was focused on BPA and thyroid hormone, however, there were other endocrine disrupting chemicals/molecules, such as phytosterols, epigallocatechin-3-gallate (ECGC), anacardic acid, zinc, berberine, etc. The phytosterol-containing treatments, which was shown to increase the levels of total thyroxine, total triiodothyronine, and free triiodothyronine, increased activity of thyroid glands.[45] EGCG can be used to treat thyroid cancer through suppressing the EGFR/RAS/RAF/MEK/ERK signaling pathway.[46]. This evidence concerns the gene TG and thyroid cancer.
