The increasing evidences have suggested that expression of single nucleotide polymorphisms (SNP) coded thyroid hormone receptors (THR) generally are associated with individual susceptibility to chemicals. In the present research, multiple molecular dynamics simulations on four SNP mutants (G332R, T337△, G345R and G347E) were performed to investigate the structural and dynamical altering, which could lead to a binding capability variation to triiodothyronine (T3). It proved the structures of two SNP mutants (G345R and T337△) occurring in the THR proteins had experienced conformational change to a great extend, which also led to a significant decreasing in binding ability with T3...

Low-intensity pulsed ultrasound (LIPUS) has been used as an adjunct to fracture healing therapies, but the mechanisms underlying its action are not known. We reported that sonic hedgehog (SHH) signaling was activated in osteoblasts at the dynamic remodeling site of a bone fracture. Mechanical stimulation is a crucial factor in bone remodeling, and it is related to the primary cilia as a sensor of hedgehog signaling. Here we observed that LIPUS promoted callus formation in accord with Gli2-positive cells after 14 days at the mouse femur fractured site compared with a control group...

Homeostasis of intraocular pressure (IOP) is important for the maintenance of anterior eye anatomic integrity, minimizing pressure-associated damage to the optic nerve, and maintaining a pressure gradient for blood flow to the eye. IOP is regulated by equilibrium between aqueous humor (AH) production and its outflow. The ciliary body (CB) is thought to actively secrete AH. However, whether AH composition and in particular, its phospholipids are entirely due to CB secretion remains uncertain. Comparison of phospholipids released by cultured CB, phospholipids present within CB tissue, within AH, and within blood and serum are consistent with release of most phospholipids into the AH by the CB...

Autologous chondrocyte implantation (ACI) has emerged as a new approach to cartilage repair through the use of harvested chondrocytes. But the expansion of the chondrocytes from the donor tissue in vitro is restricted by limited cell numbers and dedifferentiation of chondrocytes. In this study, we used four types of hydrogels including agarose, alginate, Matrigel and collagen type I hydrogels to serve as cell substrates and investigated the effect on proliferation and phenotype maintenance of chondrocytes. As a substrate for monolayer culture, collagen facilitated cell expansion and effectively suppressed the dedifferentiation of chondrocytes, as evidenced by fluorescein diacetate / propidium iodide (FDA/PI), hematoxylin-eosin staining (HE), Safranin O, immunofluorescenceassay, biochemistry analysis and quantitative real-time polymerase chain reaction (qRT-PCR)...
