Gliomas remain a major challenge in brain cancer treatment. Although genetic mutations have been widely studied, recent research indicates that epigenetic changes, which alter gene activity without changing the DNA sequence, also contribute significantly to tumor growth and treatment resistance. This review seeks to elucidate the principal drivers and modulators of brain tumor development, emphasizing the complex interaction between tumor metabolism and epigenetic regulation. It highlights how metabolic intermediates influence chromatin structure and transcriptional events driving glioma progression. Metabolic intermediates, such as acetyl-CoA and S-adenosylmethionine, serve as essential epigenetic cofactors, directly impacting chromatin structure and gene expression. Additionally, metabolic disorders like diabetes not only frequently coexist with gliomas but also exacerbate tumor progression through mechanisms such as inflammation, oxidative stress, and epigenetic reprogramming. Tumors located near brain regions controlling heart function may also increase the risk of sudden death, particularly in diabetic patients. The review proposes a comprehensive framework to understand glioma development by linking metabolism, epigenetics, and overall health. This integrated perspective leads to novel personalized treatment approaches, targeting both the tumor and the patient’s broader metabolic health, with the potential to improve survival rates and quality of life for glioma patients.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is an independent risk factor for cardiovascular disease (CVD). While gut bacteria have been linked to CVD, the role of intestinal fungi in subclinical coronary atherosclerosis (SCA) remains unclear. In this study, we aimed to investigate the association between the gut mycobiome and SCA in MASLD.

A cross-sectional study was conducted among 103 MASLD patients without established CVD. Fibrosis and steatosis were assessed using magnetic resonance elastography (MRE) and proton density fat fraction, respectively. SCA was defined by coronary artery calcification (CAC). Fecal fungal composition was analyzed via internal transcribed spacer sequencing.

Mean age was 60.8 ± 11.2 years; 51.5% were men; 20.4% had cirrhosis. CAC correlated with MRE (r = 0.489, p < 0.001), interleukin-6 (r = 0.407, p < 0.001), and tumor necrosis factor-α (r = 0.254, p = 0.018), but not proton density fat fraction. Cirrhosis patients had higher CAC than F0–F3 (456.9 vs. 205.9, p = 0.033). Candida albicans (C. albicans) abundance was greater in cirrhosis and correlated with CAC (r = 0.403, p < 0.001) and MRE (r = 0.212, p = 0.032). In multivariate analysis, older age, diabetes, obesity, cirrhosis, and enriched C. albicans independently predicted CAC ≥ 100 AU in MASLD.

In MASLD, cirrhosis and C. albicans enrichment are independently associated with higher SCA burden, suggesting advanced liver disease and a potential fungal contribution to CVD pathogenesis.

Metabolic dysfunction-associated steatotic liver disease (MASLD) affects approximately 32% of the US adult population. The present study aimed to utilize the All of Us electronic health record-linked large cohort to assess seven metabolic risk factors (MRFs) simultaneously, the impact by ethnicity and age, and clinical presentations of MASLD.

This study included a MASLD group (n = 15,060) and a frequency-matched control group (n = 75,300). Multivariable analyses were performed to compare the frequencies of MRFs and clinical outcomes between the two groups. Type 1 diabetes was not included in the multivariable analysis. Subgroup analyses were conducted according to race and ethnicity, as well as age.

The overall frequency of MASLD was 6.0%. Compared with the control group, individuals with MASLD had significantly higher independent frequencies of obesity (66.1% vs. 41.3%), type 2 diabetes (39.5% vs. 16.9%), hypertension (64.3% vs. 38.6%), hyperlipidemia (59.8% vs. 37.3%), obstructive sleep apnea (28.9% vs. 13.4%), and hypothyroidism (21.2% vs. 13.4%). Obesity was identified as the strongest independent MRF among Asians, Whites, and Hispanics, particularly in individuals younger than 50 years, whereas hypertension was the strongest independent MRF in Blacks. MASLD was also associated with significantly higher frequencies of cardiac events, including coronary artery disease (17.1% vs. 9.4%) and myocardial infarction (7.1% vs. 4.2%); hepatic events, including cirrhosis (7.5% vs. 1.1%) and hepatocellular carcinoma (0.5% vs. 0.1%); and elevated liver enzymes, including alanine aminotransferase (27.7% vs. 10.1%), aspartate aminotransferase (18.0% vs. 6.4%), and alkaline phosphatase (19.8% vs. 13.1%), compared with the control group.

Our study demonstrated that obesity, hypertension, hyperlipidemia, type 2 diabetes, obstructive sleep apnea, and hypothyroidism were independent MRFs for MASLD overall, but the ranking of these MRFs by odds ratios could vary by ethnicity and age. MASLD presents with significantly higher rates of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase elevation, as well as cardiac and hepatic events.

Terahertz (THz) radiation is increasingly explored for biomedical applications, however, its non-thermal effects on cellular metabolism and regulatory networks remain insufficiently characterized. This study aimed to investigate how 2.3 THz radiation affects metabolic pathways and membrane-associated signaling in human melanoma cells.

SK-MEL-28 melanoma cells were exposed to 2.3 THz radiation for 45 min using the 1st Novosibirsk free-electron laser. Cell viability was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and trypan blue assays. Metabolic alterations were detected by targeted metabolomics using liquid chromatography–tandem mass spectrometry. Gene network analysis was performed using the ANDSystem platform to reconstruct gene and protein interaction networks linking altered metabolites to membrane receptors, lipid raft proteins, and signaling pathways. Overrepresentation analysis of biological processes was applied to identify enriched functional categories.

THz exposure did not affect cell viability but induced significant alterations in purine metabolism, pantothenate/CoA biosynthesis, and the pentose phosphate pathway. Network analysis revealed that these metabolic changes were associated with membrane raft reorganization and receptor-mediated signaling involving epidermal growth factor receptor and G-protein subunits. Additional effects were observed in pathways related to chromatin organization and post-translational regulation.

THz radiation induces coordinated remodeling of metabolic and regulatory networks in melanoma cells without cytotoxicity. These findings highlight the role of membrane-associated signaling in mediating THz-induced cellular responses and provide insight into potential biomedical applications of THz technologies.

In the past decade, immune checkpoint inhibitors (ICIs) have dramatically changed cancer treatment, significantly improving outcomes for patients with various malignancies. Nonetheless, their widespread application has resulted in a rise in immune-related adverse events due to excessive immune activation, including immune-mediated hepatotoxicity (IMH). IMH can cause serious complications and even death, underscoring the need for early prediction and intervention. This review outlines the current understanding of risk factors and predictive biomarkers for IMH in cancer patients undergoing ICI therapy, with risk factors divided into patient-associated, tumor-associated, and agent-associated categories. Higher IMH risk is related to female sex, younger age, extreme BMI, Asian ethnicity, and chronic liver disease. Cancer type, prior ICI treatment, dual ICI combination therapy, and the concurrent use of chemotherapy, targeted agents, or other hepatotoxic drugs (e.g., acetaminophen, statins) also increase the risk of IMH. Potential predictive biomarkers encompass circulating blood cells, serum proteins, autoantibodies, cytokines, gene profiles, and the gut microbiome. Despite promising findings, the predictive value of these biomarkers remains inconsistent, and no definitive biomarker has been established for routine clinical use. Large-scale prospective studies are essential to verify the predictive value of these biomarkers and facilitate their integration into clinical practice, thereby providing deeper insights into the early identification and individualized management of IMH during ICI therapy.

Cholelithiasis and gallstone-related complications remain one of the most prevalent gastrointestinal diseases globally. Age, gender, body mass index, physical activity, dietary factors, and genetics play a role in the development of gallstones. More than 20% of patients with gallstones will develop symptomatic disease during their lifetime, which can often lead to complications and significant morbidity. Laparoscopic cholecystectomy is considered the standard of care for symptomatic gallstone disease. Still, in select patient populations and in those who are non-surgical candidates, medical management, with bile acid therapy such as ursodeoxycholic acid (UDCA) or mechanical therapy such as extracorporeal shock wave lithotripsy, is preferred. UDCA is a hydrophilic bile acid that lowers biliary cholesterol saturation and aids in dissolving small, cholesterol-rich gallstones. UDCA appears to be well tolerated in the populations studied. While serious adverse events were uncommon in the available literature, UDCA’s efficacy is limited by a high recurrence rate. The aim of this review is to summarize the current evidence and developments regarding the role of UDCA therapy in the management of cholelithiasis and choledocholithiasis.

Candida species, particularly Candida albicans, are major contributors to denture-induced stomatitis because of their ability to form biofilms on removable dental prostheses. Although chemical cleansers are effective, concerns regarding material degradation and mucosal irritation have spurred interest in non-chemical alternatives. This review aims to systematically compare the efficacy of chemical and non-chemical denture cleansers in reducing Candida spp. on removable dental prostheses.

A systematic review was conducted according to the PRISMA 2020 guidelines. Comprehensive searches of PubMed, Scopus, and Web of Science (2003–2025) yielded 624 records. After duplicate removal and screening, 20 studies (10 randomized controlled trials (RCTs) and 10 in vitro studies) were included. The risk of bias was assessed using the Cochrane Risk of Bias 2.0 for RCTs and QUIN/SYRCLE tools for in vitro studies.

Chemical cleansers such as sodium hypochlorite (0.25–2.5%), chlorhexidine (0.2–2%), and effervescent peroxide tablets achieved 80–100% colony-forming unit reduction in most studies, with some reporting complete biofilm eradication. In contrast, non-chemical agents showed a 40–85% colony-forming unit reduction rate. Chemical cleansers caused increased surface roughness and discoloration in six of the ten studies included. Non-chemical agents preserved material integrity and were preferred by patients for their taste and ease of use. The risk of bias was low to moderate in 80% of the RCTs and low in 10 of the 13 in vitro studies.

Chemical denture cleansers are more potent antifungal agents, but they may damage prosthetic materials. Non-chemical cleansers offer safe and moderately effective alternatives to chemical cleansers. A personalized, evidence-based oral hygiene regimen is recommended for patients.

Liver fibrosis is characterized by the excessive deposition of extracellular matrix, a process primarily driven by activated hepatic stellate cells (HSCs), and currently lacks effective therapy. Cathepsin K (CTSK) exhibits context-dependent roles across organ systems in fibrosis, but its function in liver fibrosis is unclear. This study aimed to investigate the role and underlying mechanisms of CTSK during liver fibrosis.

CTSK expression was analyzed in human fibrotic liver samples via transcriptomic analysis and confirmed in murine fibrosis models. The function of CTSK was investigated in both primary HSCs and LX-2 cells by assessing its effects on cell activation, proliferation, apoptosis, and the underlying signaling pathways following CTSK overexpression. The therapeutic potential was evaluated using an adeno-associated virus serotype 8 to overexpress CTSK in two etiologically distinct murine fibrosis models.

CTSK was upregulated in activated HSCs and fibrotic livers. Furthermore, we discovered that it mediates a negative feedback loop to inhibit the TGF-β/Smad pathway via Smad7/Smurf2-dependent TGF-β receptor-I degradation, thereby suppressing HSC activation and proliferation. CTSK also induced mitochondrial apoptosis through Bax/Bcl-2 imbalance and caspase-3 activation. Together, these actions contribute to the anti-fibrotic effect of CTSK. Notably, adeno-associated virus serotype 8-mediated CTSK overexpression attenuated liver fibrosis across multiple murine models.

Our study demonstrates that elevated CTSK functions as an endogenous protective factor that attenuates liver fibrosis. CTSK mediates negative feedback inhibition of the TGF-β pathway while concurrently promoting the mitochondrial apoptosis pathway. The dual anti-fibrotic mechanisms identify CTSK as a promising therapeutic target for liver fibrosis.

Cirrhotic ascites develops when portal hypertension and arterial under-filling chronically activate neuro-hormonal pathways that drive renal sodium-water retention. Augmented proximal tubular sodium reabsorption, predominantly mediated by the apical sodium/hydrogen exchanger 3 (NHE3), plays a fundamental role in this process. Given the spatial coupling of NHE3 and the sodium-glucose cotransporter 2 (SGLT2), selective SGLT2 inhibition reduces NHE3 activity via functional suppression within the apical microdomain. The increased sodium chloride delivery to the macula densa augments tubuloglomerular feedback and modulates the renin–angiotensin–aldosterone system. Early clinical investigations, ranging from case reports and retrospective analyses to pilot randomized trials, indicated potential benefits in controlling ascites and reducing decompensation events. However, their limited sample size, heterogeneous endpoints, and predominantly observational design constrain the generalizability of the findings. This review concentrates on the molecular mechanisms and emerging clinical evidence supporting the therapeutic potential of SGLT2 inhibitors in the management of cirrhotic ascites.

This review presents the Oncodarwinian Hypothesis, which proposes a new medical paradigm: that of cancer as a potential macro-immunoadaptive response (susceptible to fine-tuning or reprogramming/management via artificial intelligence-based 3D printed p53 superproteins). A traditional hypothesis-generation method was adopted; it entails observing a biophenomenon longitudinally (tumor-precursor out-of-control cell division), formulating and refining targeted research questions, and then, rooted in a prior interdisciplinary theoretical framework, outlining (per deductive reasoning) a testable answer or statement apt to predict outcomes. Two main theoretical findings emerge from this review: the plausibility of a wireless p53 superprotein molecular biochip (3D printed) and cancer cells’ dual-focus immunological nature. It will be necessary to approach the key issue and prognosis of (supposedly meaningless) uncontrolled cell division in a different light. Basically, the same diseasing cancer also constitutes a self-replicating immunoadaptive algorithm that needs to be deciphered. An interdisciplinary quest to unravel its “source code” involves genomic palaeontology and learning the natural selection programming language — for developing (personalized) artificial intelligence-assisted p53 superproteins.
