Fat mass and obesity-associated protein (FTO) has been linked to various cancers, though its role in hepatocellular carcinoma (HCC) remains unclear. This study aimed to investigate FTO expression, its clinical relevance, functional role in HCC progression, and the underlying molecular mechanisms.

Quantitative reverse-transcription polymerase chain reaction and immunohistochemical analysis were used to assess FTO expression in HCC. Functional assays, including proliferation, invasion, and epithelial-mesenchymal transition studies, were conducted using HCC cell lines with FTO knockdown. N6-methyladenosine (m6A) RNA immunoprecipitation and RNA stability assays further elucidated the role of FTO in BUB1 mRNA methylation and stability. Co-immunoprecipitation studies were employed to confirm the interaction between BUB1 and TGF-βR1. In vivo studies in nude mice were conducted to evaluate tumor growth following FTO knockdown.

FTO was significantly upregulated in HCC tissues compared to normal liver tissues, with higher expression observed in advanced tumor-node-metastasis stages and metastatic HCC. Elevated FTO correlated with poor overall survival in patients. Silencing FTO decreased HCC cell proliferation, colony formation, invasion, epithelial-mesenchymal transition, and tumor growth in nude mice. Mechanistically, FTO downregulation led to increased m6A modification of BUB1 mRNA, thereby promoting its degradation via the YTH domain family 2-dependent pathway and reducing BUB1 protein levels. Additionally, BUB1 physically interacted with TGF-βR1, activating downstream TGF-β signaling.

FTO is overexpressed in HCC and is associated with poor clinical outcomes. Mechanistically, FTO promotes HCC progression by stabilizing BUB1 mRNA through an m6A-YTH domain family 2–dependent pathway, which activates TGF-β signaling. Targeting the FTO–BUB1–TGF-βR1 regulatory network may offer a promising therapeutic strategy for HCC.

Since the adoption of novel prognostic scores, such as the iterative model for end-stage liver disease (MELD 3.0) and the gender-equity model for liver allocation (GEMA), their utility has markedly expanded to diverse clinical scenarios. However, data concerning their prognostic value in more generalized cirrhotic populations are scarce. In this study, we aimed to elucidate the MELD 3.0/GEMA-Na for long-term mortality risk stratification and refine their usage scope.

This study retrospectively reviewed 310 hospitalized patients with decompensated cirrhosis. Discrimination and stratification were compared between MELD 3.0/GEMA-Na and other scores. Validation was performed in another 120 subjects.

In the investigated cohort, the median MELD-Na, MELD 3.0, and GEMA-Na were 9 (7, 12), 12 (10, 17), and 12 (9, 17), respectively. Compared to their predecessors, both MELD 3.0 and GEMA-Na models exhibited consistently better discriminative ability, especially in relation to long-term mortality. This effect was more pronounced for GEMA-Na, which was the only score to present an area under the receiver operating characteristic curve greater than 0.8 up to two years (0.807). Statistical analysis indicated that a MELD 3.0 score of 18 and a GEMA-Na score of 20 were the most optimal cutoffs to rank the risk of death, both of which were independently associated with two-year all-cause transplant-free mortality (MELD 3.0: hazard ratio: 1.13, 95% confidence interval: 1.10, 1.17; GEMA-Na: hazard ratio: 1.12, 95% confidence interval: 1.10, 1.17, both P < 0.001). Similar findings were affirmed in the validation cohort.

MELD 3.0 is superior to other MELD-based scores for long-term prognostication in hospitalized patients with cirrhosis, while GEMA-Na demonstrated even better accuracy and performance.

Hepatocellular carcinoma (HCC) remains challenging to treat in advanced stages, primarily due to the development of resistance to sorafenib. There is an urgent need for novel therapeutic strategies to overcome this resistance. This study aimed to investigate the potential of oleanolic acid (OA), a natural hepatoprotective compound, in mitigating sorafenib resistance and elucidate its underlying molecular mechanisms.

Sorafenib-resistant Huh7 and HepG2 cell lines were established to mimic the resistant phenotype. The effects of OA on these cells were evaluated by assessing cell invasion, migration, and sensitivity to sorafenib. Gene expression analysis was conducted to identify molecular changes induced by OA treatment, with a focus on fabp3 expression.

Oleanolic acid significantly inhibited the invasive and migratory capabilities of sorafenib-resistant Huh7 and HepG2 cells (p < 0.01). Furthermore, OA treatment downregulated fabp3 expression and restored the cells’ sensitivity to sorafenib.

Oleanolic acid shows promise as an adjunct therapy for overcoming sorafenib resistance in HCC. By reducing cell aggressiveness and restoring drug sensitivity, OA may enhance the therapeutic efficacy of current treatments for advanced HCC.

Prostate cancer is the second most diagnosed cancer in men worldwide and a significant cause of cancer-related death. Proteogenomic analysis offers insights into how genomic mutations influence protein expression and can identify novel biomarkers. This study aimed to investigate the impact of missense mutations on protein abundance in prostate cancer versus healthy tissues using SILAC-based quantitative proteomics.

Mass spectrometry data from prostate tumors and adjacent healthy tissues were analyzed using stable isotope labeling. Peptides were classified based on their abundance into RefSeq and Variant Abundant groups. Missense mutations were mapped via RefSeq and dbPepVar databases. Protein intensity metrics were compared, and Spearman’s correlation was used to evaluate the relationship between mutation presence and protein abundance.

Functional enrichment revealed that RefSeq Abundant proteins are involved in normal metabolic and structural functions, while Variant Abundant proteins are enriched in tumor-related pathways such as immune evasion and apoptosis suppression. A significant negative correlation was found between protein intensity difference and ratio (p < 0.05), indicating that missense mutations contribute to altered protein expression. Mutation hotspot analysis identified recurrent alterations in genes such as PPIF and ACTB. PROVEAN was used to evaluate the functional impact of variants, identifying several as deleterious to protein stability and function.

Missense mutations are associated with altered protein abundance and may promote oncogenic processes in prostate cancer. These findings enhance the understanding of genome-proteome interactions and could support the development of targeted biomarkers and therapies.

Surgical management of supratentorial spontaneous intracerebral hemorrhage (sICH) remains controversial. Craniotomy (CT) reduces mortality but offers limited functional benefits. Neuroendoscopic surgery (NE) has emerged as a viable alternative, providing improved outcomes. Recent randomized controlled trials (RCTs) strengthen ongoing comparisons between these approaches. This meta-analysis systematically evaluates the efficacy and safety of NE versus CT for supratentorial sICH.

RCTs comparing NE versus CT for supratentorial sICH were systematically identified through comprehensive searches of PubMed, Embase, Cochrane Library, and Web of Science databases. Evaluated outcomes included functional outcome (favorable or unfavorable), hematoma evacuation rate, mortality, intraoperative blood loss, operation time, rebleeding, infection (including pulmonary and intracranial), and total complications. Cochrane’s Risk of Bias-2 tool was employed to assess the risk of bias across the included studies.

Eight RCTs were included, comprising 1,354 patients. NE demonstrated a significant advantage in achieving a favorable functional outcome (risk ratio: 1.43; 95% confidence interval (CI) 1.22, 1.68; p < 0.001) and a notably higher hematoma evacuation rate (mean difference (MD): 7.60; 95% CI 3.59, 11.61; p < 0.001). Additionally, NE was associated with a marked reduction in intraoperative blood loss (MD: −152.95; 95% CI −261.68, −44.22; p = 0.006) and a substantial reduction in operative time (MD: −118.49; 95% CI −147.30, −89.67; p < 0.001). The incidences of unfavorable functional outcome and total complications, including pulmonary infection, were significantly lower in the NE group. However, NE did not lead to an improvement in the mortality rate, and there were no significant differences in the incidences of postoperative rebleeding or intracranial infection between the two groups.

These findings suggest that NE offers distinct advantages in terms of functional outcomes and surgical efficiency for patients with supratentorial sICH. Future studies should involve larger, higher-quality RCTs, and neuroendoscopic techniques should be continuously optimized.

The refusal of blood transfusions and blood derivatives compels surgeons to face clinical and ethical challenges. We reviewed our perioperative and long-term outcomes of Jehovah’s Witnesses undergoing colon cancer surgery to evaluate the feasibility of bloodless procedures.

We retrospectively analyzed data from patients with colon cancer and Jehovah’s Witnesses who underwent surgery between January 2014 and December 2023. A protocol was systematically followed to optimize hemoglobin levels and other parameters according to the Enhanced Recovery After Surgery guidelines.

Sixteen patients underwent colon surgery, with a median age of 69 years and an equal gender distribution. Thirty-seven and a half percent had preoperative anemia and were managed by a hematologist. All procedures were performed in accordance with oncological standards. Postoperative treatment included low molecular weight heparin, and hemoglobin levels temporarily decreased postoperatively. No blood transfusions were needed during hospitalization. Two patients required surgical intervention due to postoperative hemorrhage. Complications included anastomotic dehiscence and perforation, with an overall morbidity rate of 25% and no 90-day mortality.

This study highlights the challenges in managing patients who reject blood products during colon cancer surgeries; however, the outcomes show results comparable to those of the general population with appropriate protocols. Preoperative optimization is crucial to reduce blood loss. Treatment of postoperative hemorrhage requires a lower threshold for intervention due to limited alternatives to blood products. Despite the limitations of the study, the findings advocate for careful monitoring and intervention. Larger studies are needed to validate these findings and improve care for this group of patients.

Extrahepatic portosystemic shunts (EPS) are abnormal connections between the portal and systemic circulations. Acquired EPS occur most commonly in adults and are usually associated with portal hypertension due to cirrhosis. Acquired EPS cases can be further subdivided into two types: variceal (pre-existing) EPS and non-variceal EPS (NVEPS). Variceal EPS arise from originally small vessels with pre-existing dual portal and systemic drainage. Due to elevated portal pressure, these vessels dilate and undergo a reversal of flow, sending blood back to the systemic circulation. A much less common and, therefore, underappreciated subset of acquired EPS is NVEPS, which consists of aberrant connections that did not previously exist between the portal vein and large systemic vessels, usually in the presence of portal hypertension. Neoangiogenesis results in the development of abnormal anastomoses between the portal vein and other large veins, resulting in splenorenal, gastrorenal, portocaval, and mesocaval shunts. While not uncommon, they are frequently overlooked in the diagnosis and treatment of portal hypertension and can pose significant diagnostic and therapeutic challenges. Because the treatment of variceal EPS and NVEPS can differ markedly, it is important to correctly diagnose NVEPS and institute appropriate management. The aim of this article was to review acquired EPS, with particular attention to NVEPS, updating the pathogenesis, diagnosis, and treatment.

Endometrial cancer is a common malignant tumor of the female reproductive system, and its incidence is increasing worldwide. The underlying causes of endometrial cancer are multifactorial. In recent years, the role of diet and lifestyle has received considerable attention and has become a key area of research for cancer prevention. Available literature suggests that different dietary patterns, such as the Mediterranean diet or a plant-based diet, along with moderate physical activity, are associated with a reduced risk of this cancer. Despite these findings, significant gaps in knowledge remain, particularly regarding the specific foods, lifestyle choices, and mechanisms of action that can help mitigate the risk of cancer. Furthermore, the effects of cultural and genetic differences among subpopulations make this issue even more complex. In this context, this review aimed to assess the existing literature on the potential role of diet and lifestyle factors in preventing endometrial cancer, evaluate the available data, and highlight areas that require further investigation to provide concrete evidence and recommendations for prevention.
