No data exist so far on the association of exposure to specific markers of residential air pollution during the first trimester, when neurodevelopment of the embryo is exclusively dependent on transplacental passage of maternal thyroxine.<p class="abstext...

To read the full abstract: Proc Natl Acad Sci U S A 2017;114:E11323-E11332The mechanism of thyroid hormone (TH) action is classically attributed to thyroid hormone receptor (THR) binding to thyroid hormone responsive elements (TRE) in promotors of target genes, directly controlling gene expression in target tissues. Thus, THRs alpha (TRa) and beta (TRb) function as TH dependent transcription ...

Brief summary: Villanueva-Carmona et al. identified succinate as a mediating metabolite in leptin secretion. Its action is mediated by the succinate receptor SUCNR in adipocytes via the circadian clock in an AMPK/JNK-C/EBPa-dependent manner.Although the regulatory circuits of leptin action on hunger and satiety are well understood, the pathways that mediate acute leptin production in the adipose tissue are less investigated. To investigate how a...
