Iodine is a highly reactive element with a single natural and stable isotopic form (127I). In the biosphere, it is one of the 30 essential elements for life, and its chemical speciation defines its availability and biological activities.

Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

The Iodine/Iodide/Starch Supramolecular Complex
The nature of the blue color in the iodine–starch reaction (or, in most cases, iodine–iodide-starch reaction, i.e., I2 as well as I− are typically present) has for decades elicited debate.

Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

A Study of the Mechanism of the y-Elimination Reaction of 3-Phenylpropyltrimethylammonium Iodide [PDF]
Deuterium tracer studies, kinetic isotope effect measurements and product composition studies in both ammonia and ammonia-d3 have been used to elucidate the mechanism of the y-elimination reaction of 3-phenylpropyltrimethylammonium iodide with ...

Agronomic biofortification with iodine in lettuce plants cultivated in floating hydroponic system
Iodine is essential to human metabolism, being fundamental in the production of the thyroid hormones. The consumption of biofortified foods can contribute to the increase of its intake. The objective of this study was to increase the iodine concentration

CEACAM1 participation in breast cancer progression
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Bisphenol A increases hydrogen peroxide generation by thyrocytes both in vivo and in vitro
Bisphenol A (BPA) is the most common monomer in polycarbonate plastics and an endocrine disruptor. Though some effects of BPA on thyroid hormone (TH) synthesis and action have been described, the impact of this compound on thyroid H2O2 generation remains
