Lysine-rich rice partially enhanced the growth and development of skeletal system with better skeletal microarchitecture in young rats.

Rice is the primary staple food for half of the world's population but is low in lysine content. Previously, we developed transgenic rice with enhanced free lysine content in rice seeds (lysine-rich rice), which was shown safe for consumption and improved the growth in rats. However, the effects of lysine-rich rice on skeletal growth and development remained unknown.

Improved growth performance, food efficiency, and lysine availability in growing rats fed with lysine-biofortified rice.

Rice is an excellent source of protein, and has an adequate balance of amino acids with the exception of the essential amino acid lysine. By using a combined enhancement of lysine synthesis and suppression of its catabolism, we had produced two transgenic rice lines HFL1 and HFL2 (High Free Lysine) containing high concentration of free lysine. In this study, a 70-day rat feeding study was conducted to assess the nutritional value of two transgenic lines as compared with either their wild type (WT) or the WT rice supplemented with different concentrations of L-lysine.

Sclerostin Antibody Treatment Increases Bone Formation, Bone Mass, and Bone Strength of Intact Bones in Adult Male Rats.

We investigated the systemic effect of sclerostin monoclonal antibody (Scl-Ab) treatment on intact non-operated bones in an open osteotomy male Sprague Dawley (SD) rat model. Six-month-old male SD rats were subjected to transverse osteotomy at the right femur mid-shaft. Rats were injected subcutaneously with vehicle or Scl-Ab (25 mg/kg, 2 times per week) treatment for 9 weeks.

Sclerostin, an emerging therapeutic target for treating osteoporosis and osteoporotic fracture: A general review.

Osteoporosis and its associated fracture risk has become one of the major health burdens in our aging population. Currently, bisphosphonate, one of the most popular antiresorptive drugs, is used widely to treat osteoporosis but so far still no consensus has been reached for its application in treatment of osteoporotic fractures. However, in old patients, boosting new bone formation and its remodelling is essential for bone healing in age-related osteoporosis and osteoporotic fractures.

Molecular characterization of a tomato purple acid phosphatase during seed germination and seedling growth under phosphate stress.

SlPAP1 is a phosphate starvation responsive purple acid phosphatase during tomato seed germination. Future research on its family members in tomato might improve the phosphate stress tolerance. Phosphate deficiency is a major constraint upon crop growth and yield.

Sclerostin monoclonal antibody enhanced bone fracture healing in an open osteotomy model in rats.

Sclerostin is a negative regulator of bone formation. Sclerostin monoclonal antibody (Scl-Ab) treatment promoted bone healing in various animal models. To further evaluate the healing efficiency of Scl-Ab in osteotomy healing, we investigated the time course effects of systemic administration of Scl-Ab on fracture repair in rat femoral osteotomy model.

Extracorporeal shockwave enhanced regeneration of fibrocartilage in a delayed tendon-bone insertion repair model.

Fibrous tissue is often formed in delayed healing of tendon bone insertion (TBI) instead of fibrocartilage. Extracorporeal shockwave (ESW) provides mechanical cues and upregulates expression of fibrocartilage-related makers and cytokines. We hypothesized that ESW would accelerate fibrocartilage regeneration at the healing interface in a delayed TBI healing model.

An in vivo expression system for the identification of cargo proteins of vacuolar sorting receptors in Arabidopsis culture cells.

Vacuolar sorting receptors (VSRs) are type I integral membrane family proteins that in plant cells are thought to recognize cargo proteins at the late Golgi or trans-Golgi network (TGN) for vacuolar transport via the pre-vacuolar compartment (PVC). However, little is known about VSR cargo proteins in plants. Here we developed and tested an in vivo expression system for the identification of VSR cargos which is based on the premise that the expressed N-terminus of VSRs will be secreted into the culture medium along with their corresponding cargo proteins.

Extracorporeal shockwave therapy for treatment of delayed tendon-bone insertion healing in a rabbit model: a dose-response study.

Background: Tendon-bone insertion (TBI) consists of both hard and soft tissues. TBI injury with delayed repair is not uncommon. High-dose extracorporeal shockwave (ESW) is effective for treating nonunion fracture, whereas low-dose ESW is used for tendinopathy therapy.

AtPAP2 is a tail-anchored protein in the outer membrane of chloroplasts and mitochondria.

To date, Arabidopsis purple acid phosphatase 2 (AtPAP2) is the only known plant protein that is dual-targeted to chloroplasts and mitochondria by a C-terminal targeting signal. Using in vitro organelle import and green fluorescence protein (GFP) localization assays, we showed that AtPAP2 is located on, but not imported across the outer membrane (OM) of chloroplasts and mitochondria and exposed its N-terminal enzymatic domain to the cytosol. It was also found that a short stretch of 30 amino acids (a.

A dual-targeted purple acid phosphatase in Arabidopsis thaliana moderates carbon metabolism and its overexpression leads to faster plant growth and higher seed yield.

• Overexpression of AtPAP2, a purple acid phosphatase (PAP) with a unique C-terminal hydrophobic motif in Arabidopsis, resulted in earlier bolting and a higher seed yield. Metabolite analysis showed that the shoots of AtPAP2 overexpression lines contained higher levels of sugars and tricarboxylic acid (TCA) metabolites. Enzyme assays showed that sucrose phosphate synthase (SPS) activity was significantly upregulated in the overexpression lines.

A 64 kDa sucrose binding protein is membrane-associated and tonoplast-localized in developing mung bean seeds.

Sucrose binding proteins (SBPs) were predicted to be membrane-associated, but have been shown to localize in the lumen of protein storage vacuoles of various seeds. In this study, a new 64 kDa SBP has been identified from developing mung bean (Vigna radiata) seeds (here termed VrSBP1) via MS/MS analysis and N-terminal amino acid sequencing analysis and specific antibodies were generated using purified VrSBP1 proteins. Western blot analysis with the new VrSBP1 antibodies showed that, similar to most seed storage proteins, VrSBP1 proteins accumulated during seed development and were subsequently mobilized once the mung bean seeds germinated.
