Abstract:

Background: Lead is one of the sustainable metals with devastating effects on many tissues. This study, examined the adverse effect of lead poisoning on the gene expression of collagen type II and osteocalcin by mesenchymal stem cells (MSCs) cultured in chondrogenic and osteogenic media, respectively. Methods: We used 18 male Wistar rats, divided in 3 groups. In addition to libitum feed as the control, treatment I and treatment II groups were fed by distilled water, distilled water with a dose of 50 ppm lead acetate II and distilled water with a dose of 100 ppm lead acetate II, respectively, over a 2-month period. The MSCs of rat femur were isolated in DMEM medium. After the second passage, the media were replaced separately with chondrogenic and osteogenic media over another 21 days. Then, Collagen Type II and Osteocalcin genes expression were investigated by real time PCR. Results: Collagen Type II and Osteocalcin genes expression in treatments I and II groups showed meaningful decreases compared with that of the control group. Also, the concentration of collagen type II in treatment II group in chondrogenic medium was significantly reduced compared with Osteocalcin concentration in osteogenic medium. Conclusion: We found that poisoning with lead and its accumulation at doses of 50 and 100 ppm in femoral bone marrow of rats decreased the expression of the collagen type II and osteocalcin genes in MSCs and in the chondrogenic and osteogenic media, respectively.

Effects of Oral Dosage of Lead Acetate II on Osteocalcin Gene Expression in Rat Mesenchymal Stem Cells

Background: Lead (Pb) is a heavy metal that has devastating effects on many animal tissues. In this study we investigated the effects of orally-dosed lead acetate II on osteocalcin gene (osteocalcin) expression in mesenchymal stem cells grown in an osteogenic medium. Osteocalcin is an abundant bone matrix differentiation protein. Methods: Twelve male Wistar rats were divided into three groups ...

Downregulation of Osteocalcin Gene in Chickens Treated with Lead Acetate II

Lead is one of the persistent agents found extensively in the environment and has destructive impacts on the tissues. Regarding the high spread of lead, particularly in Iran, we investigated the effects of lead acetate II on the expression level of osteocalcin gene and histological changes of bone. 40 chickens were randomly divided into four groups. As well as the libitum, the control group was...

Persister cells formation and expression of type II Toxin-Antitoxin system genes in Brucella melitensis (16M) and Brucella abortus (B19)

Background & Objective: Persister cells are defined as a subpopulation of bacteria that are capable of reducing their metabolism and switching to dormancy in stress conditions. Persister cells formation has been attributed to numerous mechanisms, including stringent response and Toxin-Antitoxin (TA) systems. This study aimed to investigate the hypothetical role of TA systems in...

Biosorption of Lead (II) and Zinc (II) ions by pre-treated biomass of phanerochaete chrysosporium

The biosorption of heavy metals can be an effective process for the removal of such metal ions from aqueous solutions. In this study, the adsorption properties of nonliving biomass of phanerochaete chrysosporium for Pb (II) and Zn (II) were investigated by the use of batch adsorption techniques. The effects of initial metal ion concentration, initial pH, biosorbent concentration, stirring speed...
