Background And Aims: The immunosuppressive tumor microenvironment (TME) plays an essential role in cancer progression and immunotherapy response. Despite the considerable advancements in cancer immunotherapy, the limited response to immune checkpoint blockade (ICB) therapies in patients with hepatocellular carcinoma (HCC) remains a major challenge for its clinical implications. Here, we investigated the molecular basis of the protein O-fucosyltransferase 1 (POFUT1) that drives HCC immune evasion and explored a potential therapeutic strategy for enhancing ICB efficacy.

Article Synopsis
  • Driver genomic mutations in tumors, like TP53 mutations in hepatocellular carcinoma (HCC), significantly affect malignancy, therapy resistance, and patient outcomes.
  • In TP53 mutant HCC, fatty acid β oxidation (FAO) is notably suppressed, leading to poor patient prognosis and tumor progression due to the downregulation of the enzyme carnitine palmitoyltransferase 1 (CPT1A).
  • The loss of CPT1A disrupts lipid metabolism and activates mTOR signaling pathways, making TP53 mutant liver cancers more sensitive to mTOR inhibitors like AZD-8055, suggesting a potential therapeutic strategy for these patients.

Background: Hepatocellular carcinoma (HCC) is one of the major causes of death from cancer and has a very poor prognosis with few effective therapeutic options. Despite the approval of lenvatinib for the treatment of patients suffering from advanced HCC, only a small number of patients can benefit from this targeted therapy.

Methods: Diethylnitrosamine (DEN)-CCL4 mouse liver tumour and the xenograft tumour models were used to evaluate the function of KDM6A in HCC progression.

Background And Aims: Epigenetic plasticity is a major challenge in cancer-targeted therapy. However, the molecular basis governing this process has not yet been clearly defined. Despite the considerable success of poly(ADP-ribose) polymerase inhibitors (PARPi) in cancer therapy, the limited response to PARPi, especially in HCC, has been a bottleneck in its clinical implications.

Objective: Aim to investigate the brucella culture characteristics, diagnosis methods, and clinical characteristics, to provide the laboratory with diagnostic methods and prevention and treatment for brucellosis.

Methods: Data of 328 cases of brucellosis from 2012 to 2022 was analyzed, retrospectively. The bacterial culture characteristics, the clinical diagnostic methods, and the complications were analyzed respectively.

We aimed to examine the association between baseline mean platelet volume/platelet count ratio (MPR) and all-cause mortality in patients with infective endocarditis (IE). This study analyzed 218 consecutive patients with IE and divided them into four groups based on MPR quartiles. We used Kaplan-Meier survival curves to determine the cumulative survival and Cox proportional hazards models to investigate the association between MPR and all-cause mortality after hospital discharge.

Nitrogen (N), phosphorus (P), and potassium (K) exert various effects on adzuki bean yields. Our research was conducted in a semi-arid area, and four test sites were established in environments that have chernozem or sandy loam soils. During a five-year period, the effects of N, P, and K fertilizers on yield were comprehensively investigated in field trials (2014-2016) and for model-implementation trials (2017-2018), with models established prior to the latter.

Mung bean (Vigna radiata L.) is an important edible bean in the human diet worldwide. However, its growth, development, and yield may be restricted or limited by insufficient or unbalanced nitrogen (N), phosphorus (P), and potassium (K) fertilization.

To study the expression of Rho kinase (Rho associated coil forming protein kinase-1, ROCK-1) and its substrate myosin phosphatase target subunit 1 (myosin phosphatase target subunit-1, MYPT-1), connexin 40 (Cx40) and connexin 43 (Cx43) in the left atrial appendage of patients with atrial fibrillation, and explore the role of ROCK signaling pathway in patients with atrial fibrillation and its underlying mechanism. Methods: 40 patients undergoing open heart surgery were divided into two groups; atrial fibrillation group (AF group) and sinus rhythm group (SR group). About 100 mg of left atrial appendage tissue was taken during surgery and quickly frozen in liquid nitrogen.

Isoflavonoids are secondary metabolites that play a variety of roles in plant-microbe interactions and plant defenses against abiotic stresses. Here we report a new MYB transcription factor (TF) gene, GmMYBJ3, that is involved in the isoflavonoids biosynthesis. The GmMYBJ3 gene is 1,002 bp long and encodes a protein of 333 amino acids.

Aim We aimed to identify clinical characteristics and risk factors associated with onset of high-altitude headache (HAH) after acute exposure at 3700 m. Method In two hours, 163 individuals ascended by plane to 3700 m. Demographic information, physiological and psychological measurements, cognitive function, physical work capacity tests and profile of mood states within one week prior to the departure and within 24 hours after arrival were examined.

This study aims to evaluate the effect of the duration of high-altitude (HA) pre-exposure on human neurobehavioral parameters including mood states and cognitive performance at HA. One hundred and eleven healthy individuals (ranging in age from 18 to 35 years) were recruited to participate in this study. They were divided into two groups: a 4-day short-term HA pre-exposure group (n=57) and a 3-month long-term HA pre-exposure group (n=54).

  • Researchers wanted to see if inhaled budesonide (BUD) could help prevent Acute Mountain Sickness (AMS) at high altitudes.
  • They tested BUD on 80 people who were going to a high place, comparing it to a placebo and other treatments for 3 days.
  • The results showed that BUD significantly reduced AMS symptoms without any side effects, possibly by helping to increase oxygen levels in the blood.

Introduction: Epidemiological studies evaluating the association of nut with risk of coronary artery disease (CAD) have produced inconsistent results. We conducted a meta-analysis to summarize the evidence from prospective cohort studies regarding the association between nut consumption and risk of CAD.

Materials And Methods: Pertinent studies were identified by searching Web of Knowledge, Pubmed and Wan Fang Med Online up to January 2014.

Aim: Previous meta-analyses have demonstrated an increased risk of adverse events in aspirin-resistant patients. In this meta-analysis, we aimed to update clinical evidence regarding the relationship between aspirin resistance and major adverse cardiovascular events (MACEs) in patients with coronary heart disease (CHD) on confirmed aspirin adherence.

Methods: An electronic literature search of PubMed, EMBASE, Web of Science and the Cochrane Library and a hand search of bibliographies through April 2013 were conducted.

Objective: The clinical evidence regarding the influence of tailored antiplatelet strategy on adverse outcomes has been controversial. The aim of the study was to evaluate the significance of tailored antiplatelet therapy with respect to clinical adverse events in antiplatelet-resistant patients.

Methods: Randomised studies that assess clinical relevance of personalised antiplatelet treatment in antiplatelet-resistant patients were identified through a literature search: PubMed, EMBASE, Web of Science and the Cochrane Library.
