Insights Into the Therapeutic Potential of SIRT1-modifying Compounds for Alzheimer's Disease: A Focus on Molecular Mechanisms.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and memory loss, significantly impacting patients' quality of life. Recent studies have highlighted the roles of sirtuin 1 (SIRT1), a NAD + -dependent deacetylase, in regulating various biological pathways associated with AD pathology, including amyloid-beta metabolism, tau hyperphosphorylation, and neuroinflammation. This review focuses on the therapeutic potential of synthetic and natural compounds that modulate SIRT1 levels, emphasizing their molecular mechanisms of action.

The Microbiota-Gut-Brain Axis in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Narrative Review of an Emerging Field.

The intricate relationship between gut microbiota and the brain has emerged as a pivotal area of research, particularly in understanding myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). This complex condition is characterized by debilitating fatigue, cognitive dysfunction, and a wide array of systemic manifestations, posing significant challenges for diagnosis and treatment. Recent studies highlight the microbiota-gut-brain axis as a crucial pathway in ME/CFS pathophysiology, suggesting that alterations in gut microbial composition may impact immune responses, neurochemical signaling, and neuronal health.

Pathological roles of lncRNA HOTAIR in liver cancer: An updated review.

Liver cancer ranks as the sixth most prevalent form of cancer and stands as the fourth leading cause of cancer-related fatalities on a global scale. The two primary types of liver cancer are hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). While ICC originates from the bile ducts, HCC develops from hepatocytes, which are the primary functional cells of the liver.
