Abstract:
Food Safety Commission of Japan (FSCJ) hosted a symposium entitled "Concept of Integrated Approaches to Testing and Assessment (IATA) Using New Approach Methods (NAMs) -Learning from the Study of Thyroid Hormone System and Developmental Neurotoxicity-" to deepen our understanding on the application of NAMs through practical examples. The symposium took place at FSCJ meeting room (Akasaka, Minato-ku, Tokyo) on December 5th, 2024, attracting a total of 21 on-site attendees as well as 153 online participants. FSCJ Chairperson Dr. YAMAMOTO gave an opening remark. In the presentation 1, Dr. AKAHORI Yumi from the Chemicals Evaluation and Research Institute, Japan (CERI), who also serves as a member of FSCJ's Working Group on Assessment Methodology Development, presented a lecture titled "International Activities Related to NAMs." In the presentation 2, Dr. Mary Gilbert from the US EPA gave a lecture titled "Thyroid Disruption and Neurodevelopment in an Adverse Outcome Framework Translating NAMs- Filling in Gaps." In the Q&A session, participants discussed about the concept and definition of NAMs. In concluding the seminar, Dr. ASANO remarked that, given the active efforts to leverage NAMs abroad led by Europe and the US, FSCJ will continue to discuss various NAMs which would be accumulated internationally and their potential applications.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
