Therefore, the FOXO1-C/EBP-ATF4 axis not only directly drives proteolysis through the ubiquitin-proteasome system but also indirectly supports these processes by elevating stress response genes like ChaC1 (Oyabu et al., 2022
ALA may be helpful for: People with diabetic neuropathy: ALA has the strongest clinical evidence for reducing nerve pain and improving quality of life in this group.1 Those with type 2 diabetes or metabolic syndrome: Modest improvements in insulin sensitivity and blood sugar markers have been observed in some studies.24 People with high oxidative stress: Research shows that ALA can help lower oxidative stress markers like CRP in individuals with chronic inflammation or metabolic risk factors.27 Those with nerve-related conditions or mitochondrial dysfunction: Early research suggests ALA may help support nerve health in contexts like multiple sclerosis.3 However, ALA may not be appropriate if: Youre generally healthy and eat a balanced diet Your body naturally produces some ALA, and small amounts are found in foods like spinach, broccoli, red meat, and organ meats.41 In healthy individuals, taking an ALA supplement may offer little to no added benefit
Among these enzymes are the Acyl-CoA Dehydrogenases (ACADs) which catalyze the , -oxidation step of fatty acids (dehydrogenation of acyl-CoA esters), and are also tightly involved in amino acid catabolism (Swigonov et al

This dysregulation sets up a feedback loop where intestinal dysbiosis and altered BA metabolism mutually reinforce each other, driving the progression of ALD.179 For instance, reduced BA secretion during ALD diminishes their bactericidal effect, leading to bacterial overgrowth in the gut.179 Additionally, BA metabolites produced by gut microbiota influence the balance of Th17 cells and Tregs, key immune players in the progression of liver disease.182 Farnesoid X receptor (FXR) is a nuclear receptor that regulates BA synthesis and modulates gut-liver communication.183 When BAs bind to FXR, they inhibit the expression of Cyp7a1/CYP7A1 (cholesterol 7-hydroxylase), a key enzyme in the BA synthesis pathway.180 FXR activation protects the liver from alcohol-induced injury by maintaining gut barrier integrity and limiting gut-derived inflammation.184 However, alcohol impairs FXR function,184 leading to gut barrier dysfunction, dysbiosis and an exacerbation of ALD progression.185 Studies have demonstrated that FXR deficiency, particularly in the intestine rather than in hepatocytes, worsens alcohol-induced liver damage.185 186 This suggests that enhancing FXR activity, especially within the gut, could be a therapeutic strategy for mitigating the harmful effects of alcohol on the liver
