Objective: The purpose of this research is to assess the antioxidant activity lemongrass leaves extract in terms lowering ROS generation and its effect on viability proliferation fibroblasts under oxidative stress. Material Methods: was measured using DPPH method assay carried out by fluorescent H2DCFDA staining. Viability assays were performed Cell Counting Kit-8 (CCK-8) read at 450 nm micropl...

Polymerase chain reaction amplification of cDNA for acidic fibroblast growth factor in several lines of cultured human cells revealed two forms of mRNA. The novel smaller mRNA lacks the entire second coding exon of the acidic fibroblast growth factor gene, whereas the previously identified mRNA consists of three coding exons. The truncated variant of acidic fibroblast growth factor (aFGF') is o...

The Role of Recombinant Fibroblast Growth Factor 1 in Enhancing the Angiogenesis Random Cutaneous Flaps Animal Model Rat

in this study, we have investigated the proliferative response of human dermal fibroblasts isolated from normal and psoriatic individuals to different cytokines. we found that il-1, tnf (α) and egf are stimulatory whereas ifn « and 1 both showed inhibitory activity on fibroblast proliferation. il-6 a more recently described cytokine, showed no detectable effects on cell proliferation. investiga...

Mononuclear cell fibroblast interactions in the normal human lung are poorly understood. Mononuclear cells can regulate fibroblast function and blood monocytes are known to migrate to the lung and participate in pulmonary inflammation. Thus, to clarify mononuclear cell-fibroblast interactions in the normal lung, we obtained supernatants from adherent monocytes and characterized their effect on ...

A polymorphism for the phase I drug-metabolizing enzyme, flavincontaining monooxygenase isoform 2 (FMO2), encoding either truncated inactive protein, FMO2X472 (FMO2.2A), or full-length active enzyme, FMO2Q472 (FMO2.1), is known and exhibits significant interethnic differences in allelic frequency. FMO2 is the major or sole FMO isoform expressed in the lung of most mammals, including nonhuman pr...

PURPOSE We have previously characterized a tumor stroma expression signature in a subset of breast tumors that correlates with better clinical outcome. The purpose of this study is to determine whether this stromal signature, termed the "DTF fibroblast" (desmoid-type fibromatosis) signature, is specific to breast cancer or is a common stromal response found in different types of cancer. EXPER...

Responding to the need for recombinant acidic fibroblast growth factor in the pharmaceutical and cosmetic industries, we established a scalable expression system for recombinant human aFGF using transient and a DNA replicon vector expression in Nicotiana benthamiana. Recombinant human-acidic fibroblast growth factor was recovered following Agrobacterium infiltration of N. benthamiana. The optim...
