Project description:An inverse correlation between circulating thyroid hormone levels and longevity has been reported in several species and reduced thyroid hormone levels have been proposed as a biomarker for healthy aging and metabolic fitness in humans. However, hypothyroidism is a serious medical condition associated with reduced health and life expectancy. In this report, we show that severe and even subtle modulations on thyroid hormone levels leading to different forms of hyperthyroidism and hypothyroidism produce an overall unhealthy status and reduced lifespan in mice. A mild reduction in circulating T4 levels (~10%) resulted in hepatic mitochondrial dysfunction, increased ROS production and oxidative damage accumulation. These actions may contribute to the development of metabolic disorders, increased prevalence of hepatocellular carcinomas and early mortality in mice. Our findings raise concerns regarding the development of interventions aiming to modulate thyroid hormones to promote healthy aging or lifespan extension in mammals.

Project description:The function of the thyroid gland is to metabolize iodide to synthesize hormones that act on almost all tissues and are essential for normal growth and metabolism. Low plasma levels of thyroid hormones lead to hypothyroidism, which is one of the most common diseases in the general population and cannot be always satisfactorily treated by lifelong hormone replacement. Therefore, in addition to the lack of in vitro tractable models to study human thyroid development, differentiation and maturation, there is a need for new therapeutic approaches that involve replacement of thyroid tissue to better control hormone balance. Here we report the first model of thyroid organoids derived from human embryonic stem cells that produce thyroid hormones in vitro and are capable of restoring plasma thyroid hormone levels when transplanted into athyreotic mice.

Project description:We have found that thyroid hormones (THs), acting as soluble integrin αvβ3 ligands, activate growth-related signaling pathways in T-cell lymphomas (TCL). Specifically, TH-activated αvβ3 integrin signaling promotes TCL proliferation and angiogenesis, in part, via the up-regulation of VEGF.

Specifically, TH-activated αvβ3 integrin signaling promotes TCL proliferation and angiogenesis, in part, via the up-regulation of VEGF. CUTLL1 cells were treated with T3- and T4-bound agarose or agarose alone for 24hrs. Total RNA was harvested from cells and used for expression profiling via RNA-seq.

Project description:The thyroid gland is responsible for supplying the thyroid hormones to the body. The gland is an endocrine organ with an intricate structure enabling production, storage and release of the thyroid hormones. The gland is composed of numerous spherical follicles of varying sizes, surrounded by thyroid follicular epithelial cells, or thyrocytes. The thyrocytes surrounding the follicles generate the thyroid hormones in a multi-step process. Though the machinery responsible for the production of thyroid hormones by thyrocytes is well established, it remains unknown if all the thyrocytes resident in the thyroid gland are equally capable of generating thyroid hormones. In other words, the extent of molecular homogeneity between individual thyrocytes has not yet been investigated. To obtain an unbiased picture into the molecular heterogeneity present in zebrafish thyrocytes, we performed droplet based next-generation sequencing of individual thyrod gland cells. Using unsupervised clustering, we could identify all the major cell types present in the thyroid gland. Moreover, we could define sub-populations within the major cell-types, demonstrating the presence of molecular heterogeneity within nominally homogenous cell-populations.

Project description:Notch signaling between neighboring cells vitally contributes to specifying their identity and function, during development and in the adult. Here, we demonstrate that selective blockade of the Notch ligands JAG1 and JAG2 disrupts thermoregulation in adults by decreasing circulating thyroid hormones and thyroid function. Sequencing data in BAT demonstrates that Notch inhibition increases thermoregulation genes and this depends on thyroid hormones.
