Buchanania lanzan Spreng. (Anacardiaceae) seeds (BLHA) are the cheaper alternative to almonds used in the confectionery industry. The flour powder of seeds is used as a thickening agent to prepare sauces and flavourings for a batter. The socioeconomic importance of this species lies in its medicinal properties for curing diabetes. The study explored the multifaceted neuroprotective role of BLHA (500 mg/kg) in hyperlipidic high-fat diet streptozotocin (HFD/STZ)-induced type2 diabetic neuropathy (T2DN) rats via glucose metabolism, insulin resistance, and inflammation to mitigate nerve damage. Molecular docking analysis was performed to identify specific molecular targets of bioactive compounds in T2DN pathogenesis. Serum diabetic parameters, such as serum glucose (SG), insulin (SI), total protein (TP), triglycerides (TG), blood urea nitrogen (BUN), creatinine (Cr), HDL-C, and LDL-C, were studied. A strong correlation between HbA1C and insulin resistance assessed by HOMA-IR. Oxidative stress triggers the production of free radicals, so the antioxidant indicators in serum, tissues, and proinflammatory cytokines in the liver, brain, and pancreas were measured in T2DN rats. Effects on neurochemicals, BACE1, Aβ BLHA at 500 mg/kg significantly improved hyperglycemic (SG, SI, HOMA-IR, HbA1C), hepatic (AST, ALT, ALP, TP, TB), dyslipidemic (TC, TG, HDL-C, LDL-C), and kidney function markers (creatinine, BUN) in T2DN rats. BLHA restored oxidative (CAT, GSH, SOD, MDA) and cytokine markers (TNF-α, IL6) in the liver, pancreas, and brain cortex. Oxidative stress-impaired neurotransmitters were alleviated by enhancing cholinesterase (AChE, BChE) and BACE1 activities, and by ameliorating Aβ The multifaceted actions of dietary polyphenols, antioxidants, and antidiabetic compounds (Catechol, 2-Hydroxy-5-methylbenzaldehyde, 8-Octadecenoic acid methyl ester, n-Hexadecanoic acid, 2-hydroxy-1-(hydroxymethyl)ethyl ester, β-Sitosterol, Hexadecenoic acid methyl ester) in BLHA modulated glucose metabolism, restored HOMA-IR, and reduced inflammation by protecting against oxidative stress, as a result, it improved neurotransmission and reduced neuropeptide aggregation in T2DN rats. The dock score of β-sitosterol (AChE: -12.7; BChE: -14.8; IL6: -9.8; and Atp1a3: -13.3 kcal/mol) correlated with the experimental evidence. Show less

Dyslipidemia is the leading cause of cardiovascular disease (CVD) in Type 2 diabetes mellitus patients. As a result, it is critical to target and manage the level of atherogenic lipids. Angiopoietin-like proteins 3 and 4 (ANGPTL 3 and ANGPTL 4) play an important role in the intravascular lipolysis of triglyceride-rich lipoproteins by blocking the enzyme lipoprotein lipase. This study aimed to determine the amounts of these angiopoietin-like proteins in T2DM and find their association with dyslipidemia in T2DM. Sixty-one T2DM patients of age group 25-65 years and 27 healthy age-matched control participants were enrolled in the study. Glycemic status (FBS, PPBS, HbA1C), serum lipid parameters (cholesterol, TG, LDL, VLDL, HDL, Tc/HDL ratio), free fatty acid, serum insulin, and ANGPTL3, 4 were measured. A correlation was found between the ANGPTLs and the above parameters in T2DM patients. Serum ANGPTL3 ( This study shows that ANGPTL 3,4 may be associated with dyslipidemia in T2DM. ANGPTL4 is more correlated with glycemic status. Show less

Nutritional status of the mother is known to influence various metabolic adaptations required for optimal fetal development. These may be mediated by transcription factors like peroxisome proliferator activated receptors (PPARs), which are activated by long chain polyunsaturated fatty acids. The objective of the current study was to examine the expression of different hepatic transcription factors and the levels of global methylation in the liver of the offspring born to dams fed micronutrient deficient (folic acid and vitamin B12) diets and supplemented with omega-3 fatty acids. Female rats were divided into five groups (n = 8/group) as follows; control, folic acid deficient (FD), vitamin B12 deficient (BD) and omega-3 fatty acid supplemented groups (FDO and BDO). Diets were given starting from pre-conception and continued throughout pregnancy and lactation. Pups were dissected at the end of lactation. Liver tissues were removed; snap frozen and stored at -80°C. Maternal micronutrients deficiency resulted in lower (p<0.05) levels of pup liver docosahexaenoic acid (DHA) and arachidonic acid (ARA) as compared to the control group. Pup liver PPARα and PPARγ expression was lower (p<0.05) in the BD group although there were no differences in the expression of SREBP-1c, LXRα and RXRα expression. Omega-3 fatty acids supplementation to this group normalized (p<0.05) levels of both PPARα and PPARγ but reduced (p<0.05) SREBP-1c, LXRα and RXRα expression. There was no change in any of the transcription factors in the pup liver in the FD group. Omega-3 fatty acids supplementation to this group reduced (p<0.05) PPARα, SREBP-1c and RXRα expression. Pup liver global methylation levels were higher (p<0.01) in both the micronutrients deficient groups and could be normalized (p<0.05) by omega-3 fatty acid supplementation. Our novel findings suggest a role for omega-3 fatty acids in the one carbon cycle in influencing the hepatic expression of transcription factors in the offspring. Show less
