Endoplasmic Reticulum Stress Inducer Tunicamycin Invoked Oxidative Stress,and Altered Hepatic Energy Homeostasis Were Ameliorated By Farnesol In Mouse

The endoplasmic reticulum stress(ERS),is described via the accumulation of unfolded protein response(UPR)in endoplasmic reticulum(ER).In the liver,ER homeostasis plays a significant role in protein maintenance,anything that affects the ability of ER to mature proteins can extensively damage cell and progress diseases in various body parts.The liver is a primary metabolic organ,play an essential role in the regulation of carbohydrate and lipid metabolism,as well as production and secretion of plasma proteins.Recent evidence suggests that ERS response can modify the energy homeostasis in the liver via regulating the expression of numerous genes that play a crucial role in energy metabolism.Researchers exploring the part of ERS expression that each of the three principal reasons for hepatic destruction(obesity,alcoholism,and hepatitis)leads to ERS and UPR activation in the liver.Indeed,recent research to induce ERS by tunicamycin(TM),a pharmacological stress inducer identified a compound that responsible for protein misfolded/unfolded,thus increasing protein load and damage the organ.However,the prevalence of ERS inducer TM invoked oxidative stress,and altered hepatic energy homeostasis leads to a broad range of hepatic disorders since it expressively rises the possibility of emerging diseases and associated damage of the liver cells.As a result,ERS might also play a role in functional irregularities concerned by way of those cases.Consequently,there is an urgent need to catch unique treatments which can stop ERS inducer TM invoked oxidative stress and adjust hepatic energy homeostasis and the progress of correlated problems.Currently,a wide range of research attention on the naturally occurring plants and it’s by-products targeting oxidative damage and changed hepatic homeostasis,which results in benefits to animal and human diseases.Farnesol(FOH)compound was chosen based on current studies signifying they have several pharmacological properties.Studies have experimented with the hypothesis individually cell and animal model.Primarily,the cell studies were carried out with different doses of FOH was not cytotoxic to hepatocytes at a concentration of 25 μM.To investigate the inhibitory effect of FOH on TM invoked disorders.TM was added into the DMEM cell culture medium,and incubation was continued in the presence and absence of FOH for 6 h.According to results,in this experiment,we found that FOH treatment in the cell model plays a significant role to defend hepatocytes and weaken the gene expression on several stages.FOH treatment improves the activity of hepatocytes during the exposure of ERS inducer TM significantly(P<0.05)up-regulated ERS gene expression of Chop,Grp78,and Atf4 in the primary hepatocytes.FOH ameliorate the TM up-regulated hepatic energy homeostasis related gene expression significantly(P<0.05)such as Srebp1 c,Cpt1a,Pepck,G6pase(except Scd1,Fas downregulated).These results put forward that FOH potency is useful to prevent ERS altered hepatic homeostasis and developments of hepatic pathophysiology.Based on cell study,for further verification similarly,we test in an animal model.The mice were injected intraperitoneally with Vehicle as a control group;ERS was induced by TM challenge and FOH+TM group.At the end of experiment,we speculate FOH had no significant effect on body weight of experimental mice.Subsequently,liver glycogen,triglycerides,and non-esterified fatty acid content and blood serum profile were analyzed,along with oxidative stress and altered hepatic energy homeostasis related genes.As compared to the control group,TM significantly(P<0.05)increase the blood serum alanine transaminase and serum aspartate transaminase level.Besides,TM expressively increased(P<0.05)liver triglycerides and non-esterified fatty acid.Furthermore,TM treatment significantly(P<0.05)reduced blood serum glucose,triglycerides,total cholesterol,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,and hepatic glycogen.Additionally,oxidative stress,and m RNA relative expression of ERS and hepatic energy homeostasis relevant genes analysis.Interestingly,we found that FOH+TM treatment attenuates the ERS genes Chop,Grp78,and Atf4 during TM exposure;however,not reach the level of statistical significance in liver tissue of mice.Moreover,altered hepatic energy homeostasis genes Srebp1 c,Cpt1a,Pepck,G6 pase,Scd1,and Fas were significantly returned by FOH+TM treatment,which was affected via TM exposure.The oxidative activity of SOD and GSH were observed significantly low(P<0.05),while the content of MDA was noted considerably high(P<0.05)in liver tissue of TM exposure group than those in FOH+TM treated group.Furthermore,hematoxylin and eosin analysis revealed that liver tissue of FOH+TM group of mice significantly(P<0.05)improved.Taken together,data from these experiments indicate that FOH ameliorates oxidative stress and restore energy homeostasis.In summary,the results exposed that TM exposure to hepatic tissue could increase oxidative damage and changed hepatic energy homeostasis in liver tissue of mice by inducing histopathological,morphological,oxidative,serum biomarker changes,and by initiating m RNA expression of several associated genes.Moreover,the present study will facilitate a better understanding of FOH efficacy against ERS inducer tunicamycin invoked oxidative stress and the altered environment in liver tissue of mice.Nevertheless,FOH showed an upper hand in delaying hepatic disorders and oxidative stress.
