Abstract
Trigonelline (TRG) is a natural polar hydrophilic alkaloid that is found in many plants such as green coffee beans and fenugreek seeds. TRG potentially acts on multiple molecular targets, including nuclear factor erythroid 2-related factor 2 (Nrf2), peroxisome proliferator-activated receptor γ, glycogen synthase kinase, tyrosinase, nerve growth factor, estrogen receptor, amyloid-β peptide, and several neurotransmitter receptors. In this review, we systematically summarize the pharmacological activities, medicinal properties, and mechanistic actions of TRG as a potential therapeutic agent. Mechanistically, TRG can facilitate the maintenance and restoration of the metabolic homeostasis of glucose and lipids. It can counteract inflammatory constituents at multiple levels by hampering pro-inflammatory factor release, alleviating inflammatory propagation, and attenuating tissue injury. It concurrently modulates oxidative stress by the blockage of the detrimental Nrf2 pathway when autophagy is impaired. Therefore, it exerts diverse therapeutic effects on a variety of pathological conditions associated with chronic metabolic diseases and age-related disorders. It shows multidimensional effects, including neuroprotection from neurodegenerative disorders and diabetic peripheral neuropathy, neuromodulation, mitigation of cardiovascular disorders, skin diseases, diabetic mellitus, liver and kidney injuries, and anti-pathogen and anti-tumor activities. Further validations are required to define its specific targeting molecules, dissect the underlying mechanistic networks, and corroborate its efficacy in clinical trials.

Genetic investigation into the broad health implications of caffeine: evidence from phenome-wide, proteome-wide and metabolome-wide Mendelian randomization. BMC Med 2024; 22:81. [PMID: 38378567 PMCID: PMC10880284 DOI: 10.1186/s12916-024-03298-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Accepted: 02/12/2024] [Indexed: 02/22/2024] Open
Abstract
BACKGROUND Caffeine is one of the most utilized drugs in the world, yet its clinical effects are not fully understood. Circulating caffeine levels are influenced by the interplay between consumption behaviour and metabolism. This study aimed to investigate the effects of circulating caffeine levels by considering genetically predicted variation in caffeine metabolism. METHODS Leveraging genetic variants related to caffeine metabolism that affect its circulating levels, we investigated the clinical effects of plasma caffeine in a phenome-wide association study (PheWAS). We validated novel findings using a two-sample Mendelian randomization framework and explored the potential mechanisms underlying these effects in proteome-wide and metabolome-wide Mendelian randomization. RESULTS Higher levels of genetically predicted circulating caffeine among caffeine consumers were associated with a lower risk of obesity (odds ratio (OR) per standard deviation increase in caffeine = 0.97, 95% confidence interval (CI) CI: 0.95-0.98, p = 2.47 × 10-4), osteoarthrosis (OR = 0.97, 95% CI: 0.96-0.98, P=1.10 × 10-8) and osteoarthritis (OR: 0.97, 95% CI: 0.96 to 0.98, P = 1.09 × 10-6). Approximately one third of the protective effect of plasma caffeine on osteoarthritis risk was estimated to be mediated through lower bodyweight. Proteomic and metabolomic perturbations indicated lower chronic inflammation, improved lipid profiles, and altered protein and glycogen metabolism as potential biological mechanisms underlying these effects. CONCLUSIONS We report novel evidence suggesting that long-term increases in circulating caffeine may reduce bodyweight and the risk of osteoarthrosis and osteoarthritis. We confirm prior genetic evidence of a protective effect of plasma caffeine on risk of overweight and obesity. Further clinical study is warranted to understand the translational relevance of these findings before clinical practice or lifestyle interventions related to caffeine consumption are introduced.

Comput Struct Biotechnol J 2023; 21:4552-4566. [PMID: 37799542 PMCID: PMC10550404 DOI: 10.1016/j.csbj.2023.09.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 09/12/2023] [Accepted: 09/19/2023] [Indexed: 10/07/2023] Open
Abstract
Caffeine is a well-known purine alkaloid commonly found in coffee. Several lines of previous and recent evidence have shown that habitual coffee drinking is associated with lower risks for chronic kidney disease (CKD) and nephrolithiasis. However, cellular and molecular mechanisms underlying its renoprotective effects remain largely unknown due to a lack of knowledge on cellular adaptive response to caffeine. This study investigated cellular adaptive response of renal tubular cells to caffeine at the protein level. Cellular proteome of MDCK cells treated with caffeine at a physiologic concentration (100 μM) for 24 h was analyzed comparing with that of untreated cells by label-free quantitative proteomics. From a total of 936 proteins identified, comparative analysis revealed significant changes in levels of 148 proteins induced by caffeine. These significantly altered proteins were involved mainly in proteasome, ribosome, tricarboxylic acid (TCA) (or Krebs) cycle, DNA replication, spliceosome, biosynthesis of amino acid, carbon metabolism, nucleocytoplasmic transport, cell cycle, cytoplasmic translation, translation initiation, and mRNA metabolic process. Functional validation by various assays confirmed that caffeine decreased cell population at G2/M, increased cell population at G0/G1, increased level of ubiquitinated proteins, increased intracellular ATP and enhanced mitochondrial membrane potential in MDCK cells. These data may help unravelling molecular mechanisms underlying the biological effects of caffeine on renal tubular cells at cellular and protein levels.
