Surfactant protein B (SP-B8), an 8-kDa hydrophobic protein essential for surfactant and normal lung function, is produced from the intracellular processing of preproSP-B. To characterize SP-B processing in human type 2 cells, we used human fetal lung in explant culture and polyclonal antibodies to human SP-B8(Phe201-Met279) and to specific epitopes within the NH2- and COOH-terminal propeptide d...

Osteoporosis is a major health issue. By 2050, greater than 2-fold increase in patients number with hip fractures will occur Asia representing 50% of all worldwide. For the Asia-Pacific (AP) region, more efforts on controlling osteoporosis and subsequent are crucial. Bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA) commonly used to diagnose monitor treatment. However, inconv...

Aim: The intent of the study was to assess bone conserving effect Butea monosperma total extract (BTE) prepared from stem-bark, in ovariectomy (Ovx)-induced loss Sprague Dawley (SD) rats.
 Methods: Sprague-Dawley rats were ovariectomized (Ovx) and BTE treatment with three different doses (100mg, 250mg 500mg/kg body weight) commenced a day after Ovx continued for 12 weeks. Skeletal paramete...

Pseudomonas aeruginosa elastase and the LasA protease are synthesized as preproenzymes with long amino-terminal propeptides. The elastase propeptide is cleaved autocatalytically in the periplasm to form a transient, inactive elastase-propeptide complex. In contrast, the processing of proLasA does not involve autoproteolysis. In this study, we analyzed short-term P. aeruginosa cultures under con...

Cardiac interstitial fibrillar collagen accumulation, such as that associated with chronic pressure overload (PO), has been shown to impair left ventricular diastolic function. Therefore, insight into cellular mechanisms that mediate excessive collagen deposition in the myocardium is pivotal to this important area of research. Collagen is secreted as a soluble procollagen molecule with NH(2)- a...

Objectives: To establish reference ranges for serum bone turnover markers including Osteocalcin (OC), Procollagen type 1 amino-terminal propeptide (P1NP), and Beta-CrossLaps (beta-CTX) in premenopausal women at University Medical Center, Ho Chi Minh City. Methods: A cross-sectional study was conducted on 157 aged 20 to 44 years City from December 2022 February 2023. Demographic information, bio...

Diverging results have been published concerning collagen metabolism in uterovaginal prolapse (UP). We have investigated collagen turnover in urogenital tissue in urologically healthy women with (UP patients) and without UP or any history of UP (controls). Markers of collagen turnover, carboxy-terminal propeptide of type I procollagen (PICP), amino-terminal propeptide of procollagen III (PIIINP...

Arabidopsis RD21 is a cysteine protease of the papain family. Unlike other members of the papain family, RD21 has a C-terminal extension sequence composed of two domains, a 2-kD proline-rich domain and a 10-kD domain homologous to animal epithelin/granulin family proteins. The RD21 protein was accumulated as 38- and 33-kD proteins in Arabidopsis leaves. An immunoblot showed that the 38-kD prote...
