Omega-3 fatty acid supplementation does not influence liver regeneration in rats after partial hepatectomy. Clin Exp Hepatol 2018; 4:253-259. [PMID: 30603673 PMCID: PMC6311744 DOI: 10.5114/ceh.2018.80127] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2018] [Accepted: 06/05/2018] [Indexed: 02/07/2023] Open
Abstract
Aim of the study In the initiation of liver regeneration, multiple stimulatory and inhibitory factors participate. In this study, we aimed to evaluate the effects of omega-3 fatty acids on liver regeneration after 30% partial hepatectomy in rats. Material and methods A total of 14 male Wistar Albino rats were included in this study. The animals were randomly allocated to two groups: the control group (n = 7) and the omega-3 group (n = 7). Rats in the control group were fed a standard rat chow and rats in the omega-3 group received 10 mg/kg/day omega-3 supplementation in addition to normal rat chow in the perioperative period. Rats were investigated seven days after 1/3 partial hepatectomy by liver weight change and hepatocyte proliferation. Results The mean liver regeneration rate was found to be slightly higher (p = 0.061) in the omega-3 group compared the control group. In addition, no significant difference was observed regarding binuclear hepatocyte ratio in pericentral and periportal areas between the two groups. However, livers from rats given omega-3 supplementation have less inflammatory cellular infiltrate in the portal space than livers from the control group. Conclusions Supplementation with omega-3 fatty acids showed no influence on the liver regeneration in rats undergoing 1/3 partial hepatectomy.

Beharry KD, Cai CL, Henry MM, Chowdhury S, Valencia GB, Aranda JV. Co-Enzyme Q10 and n-3 Polyunsaturated Fatty Acid Supplementation Reverse Intermittent Hypoxia-Induced Growth Restriction and Improved Antioxidant Profiles in Neonatal Rats. Antioxidants (Basel) 2017; 6:E103. [PMID: 29258174 PMCID: PMC5745513 DOI: 10.3390/antiox6040103] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Revised: 12/08/2017] [Accepted: 12/14/2017] [Indexed: 12/20/2022] Open
Abstract
Neonatal intermittent hypoxia (IH) increases the risk for many morbidities in extremely low birth weight/gestational age (ELBW/ELGA) neonates with compromised antioxidant systems and poor growth. We hypothesized that supplementation with coenzyme Q10 (CoQ10, ubiquinol) or n-3 polyunsaturated fatty acids (PUFAs) during neonatal IH improves antioxidant profiles and somatic growth in neonatal rats. Newborn rats were exposed to two IH paradigms at birth (P0): (1) 50% O₂ with brief hypoxic episodes (12% O₂); or (2) room air (RA) with brief hypoxia, until P14 during which they received daily oral CoQ10 in olive oil, n-3 PUFAs in fish oil, or olive oil only from P0 to P14. Pups were studied at P14 or placed in RA until P21 for recovery from IH (IHR). Body weight and length; organ weights; and serum antioxidants and growth factors were determined at P14 and P21. Neonatal IH resulted in sustained reductions in somatic growth, an effect that was reversed with n-3 PUFAs. Improved growth was associated with higher serum growth factors. CoQ10 decreased superoxide dismutase (SOD) and glutathione, but increased catalase, suggesting reduced oxidative stress. Further studies are needed to determine the synergistic effects of CoQ10 and n-3 PUFA co-administration for the prevention of IH-induced oxidative stress and postnatal growth deficits.

Omega-3 Polyunsaturated Fatty Acids Intake to Regulate Helicobacter pylori-Associated Gastric Diseases as Nonantimicrobial Dietary Approach. BIOMED RESEARCH INTERNATIONAL 2015; 2015:712363. [PMID: 26339635 PMCID: PMC4538587 DOI: 10.1155/2015/712363] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/26/2014] [Revised: 12/20/2014] [Accepted: 01/15/2015] [Indexed: 02/07/2023]
Abstract
Omega-3 polyunsaturated fatty acids (n-3 PUFAs), commonly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been acknowledged as essential long-chain fatty acids imposing either optimal health promotion or the rescuing from chronic inflammatory diseases such as atherosclerosis, fatty liver, and various inflammatory gastrointestinal diseases. Recent studies dealing with EPA and DHA have sparked highest interests because detailed molecular mechanisms had been documented with the identification of its receptor, G protein coupled receptor, and GPR120. In this review article, we have described clear evidences showing that n-3 PUFAs could reduce various Helicobacter pylori- (H. pylori-) associated gastric diseases and extended to play even cancer preventive outcomes including H. pylori-associated gastric cancer by influencing multiple targets, including proliferation, survival, angiogenesis, inflammation, and metastasis. Since our previous studies strongly concluded that nonantimicrobial dietary approach for reducing inflammation, for instance, application of phytoceuticals, probiotics, natural products including Korean red ginseng, and walnut plentiful of n-3 PUFAs, might be prerequisite step for preventing H. pylori-associated gastric cancer as well as facilitating the rejuvenation of precancerous atrophic gastritis, these beneficial lipids can restore or modify inflammation-associated lipid distortion and correction of altered lipid rafts to send right signaling to maintain healthy stomach even after chronic H. pylori infection.

Rat hepatocytes weighted gene co-expression network analysis identifies specific modules and hub genes related to liver regeneration after partial hepatectomy. PLoS One 2014; 9:e94868. [PMID: 24743545 PMCID: PMC3990548 DOI: 10.1371/journal.pone.0094868] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2013] [Accepted: 03/19/2014] [Indexed: 11/20/2022] Open
Abstract
The recovery of liver mass is mainly mediated by proliferation of hepatocytes after 2/3 partial hepatectomy (PH) in rats. Studying the gene expression profiles of hepatocytes after 2/3 PH will be helpful to investigate the molecular mechanisms of liver regeneration (LR). We report here the first application of weighted gene co-expression network analysis (WGCNA) to analyze the biological implications of gene expression changes associated with LR. WGCNA identifies 12 specific gene modules and some hub genes from hepatocytes genome-scale microarray data in rat LR. The results suggest that upregulated MCM5 may promote hepatocytes proliferation during LR; BCL3 may play an important role by activating or inhibiting NF-kB pathway; MAPK9 may play a permissible role in DNA replication by p38 MAPK inactivation in hepatocytes proliferation stage. Thus, WGCNA can provide novel insight into understanding the molecular mechanisms of LR.
