The high molecular weight melanoma-associated antigen (HMW-MAA) is a membrane-bound chondroitin sulphate proteoglycan that is highly expressed on the surface of melanoma cells. It represents an attractive target for immunotherapy of malignant melanoma. Previously, it was reported that HMW-MAA was detected in about 20-30% of primary acral lentiginous melanoma (ALM) lesions by immunohistochemical...

The popularity of wheat flour tortillas is spreading throughout the world and has become one highest-selling bread products. USDA Southern Regional Performance Nursery (SRPN) serves as largest wheat-growing region in USA, but tortilla quality germplasm SRPN remained unknown. This study investigated kernel traits, dough rheological properties, parameters, glutenin composition 131 lines from 1995...

Monoclonal antibodies (MoAbs) 225.28, 657.9, and 902.5 recognizing distinct epitopes of the human high molecular weight melanoma associ ated antigen (HMW-MAA) were used to investigate the molecular and cellular heterogeneity of the HMW-MAA synthesized by human mela noma cells. Sequential immunodepletion and immunoprecipitation exper iments showed that not all HMW-MAA molecules synthesized by a ...

The method of quasi-elastic light-scattering spectroscopy was used to establish quantitatively the concentration of high mmolecular weight (HMW) aggregates present in the normal human intact lens as a function of age. The concentration of HMW proteins increases monotonically with age. HMW proteins are absent in the infant lens, but represent 3% of the total soluble lens protein at age 60 years....

AIM To look at the association of total and high molecular weight (HMW) adiponectin with markers of fat distribution, oxidative stress and inflammation in Asian Indians. METHODS A total of 120 subjects were chosen randomly from Chennai Urban Rural Epidemiological Study. Fasting HMW adiponectin levels, TNF-alpha and oxidized LDL were measured using ELISA. High sensitivity C reactive protein (h...

The T-cell-dependent antibody response (TDAR) is a functional assay used in immunopharmacology and immunotoxicology to assess ability to mount an antibody response to immunization. Keyhole limpet hemocyanin (KLH) is extensively used as the immunogen of choice in non-clinical and clinical settings. Native KLH is comprised of high molecular weight (HMW; 4-8 MDa) assemblies of KLH subunit dimers (...

Human glioblastoma multiforme (GBM) is the most malignant tumor of the central nervous system (CNS). Fibroblast growth factor-2 (FGF2) belongs to the FGF superfamily and functions as a potential oncoprotein in GBM. FGF2 has low molecular weight (18K) and high molecular weight (HMW) isoforms. Nuclear accumulation of HMW-FGF2 strongly promotes glioblastoma cell proliferation, yet mechanism govern...

In view of reports on the involvement of high-molecular-weight (HMW) kininogen and high-density lipoprotein (HDL) in the Vroman effect, we studied the adsorption of fibrinogen, HMW kininogen, HDL and several other proteins from pooled human plasma and congenitally HMW kininogen-deficient plasma onto glass and low-density polyethylene, both as a function of the plasma concentration and the conta...

Impaired angiogenesis contributes to delayed wound healing in aging. Hyaluronan (HA) has a close relationship with angiogenesis and wound healing. However, HA content decreases with age. In this study, we used high molecular weight HA (HMW-HA) (1650 kDa), and investigated its effects on wound healing in old rats by local injection. We found that HMW-HA significantly increases proliferation, mig...
