With the emergence of unhealthy dietary structures in people’s life, metabolic associated fatty liver disease (MAFLD) has gradually become the most important chronic liver disease in China, and there is also a gradual increase in the cases of MAFLD-associated liver cancer. Adipose tissue not only has the function of energy storage, but also secretes adipokines that play an important role in the development and progression of MAFLD and its associated liver cancer. Studies on the mechanism of adipokines have provided important help for the prevention and treatment of MAFLD, and a large number of studies have shown that the abnormal secretion of adipokines is associated with MAFLD and plays an important regulatory role in the development and progression of liver cancer. Adipokines are not only regulated at the gene level, but they can also interact with genes through specific pathways to co-regulate pathophysiological processes such as inflammation, metabolism, immunity, and cell proliferation in MAFLD and its associated liver cancer. This article reviews the latest studies on the association of adipokines with MAFLD and its associated liver cancer, in order to provide new directions for further research on the pathogenesis of liver cancer.

ObjectiveTo investigate the therapeutic effect of Dayuanyin on acute lung injury induced by H1N1 infection and decipher the potential mechanism. MethodThe constituents in Dayuanyin were analyzed by ultra-high performance liquid chromatography-quadrupole-exactive orbitrap mass spectrometry (UHPLC-Q-Exactive Orbitrap MS). Forty-eight female BALB/c mice were randomized into normal, model, oseltamivir (19.5 mg·kg-1), and low-, medium-, and high-dose (2.73, 5.46, 10.92 g·kg-1) Dayuanyin groups. The normal and model groups were administrated with deionized water by gavage, and the other groups were administrated with the corresponding drugs by gavage. On day 3 of drug administration, the normal group received nasal inhalation of normal saline, and the other groups were inoculated intranasally with A/RP/8/34 (H1N1) for the modeling of influenza virus infection. Mice were administrated with drugs continuously for 7 days and weighed daily. Sampling was performed 12 h after the last administration, and the lung tissue was weighed to calculate the lung index. Hematoxylin-eosin staining was performed to observe the pathological and morphological changes of the lung tissue and bronchi. The cytometric bead array (CBA) was used to measure the serum levels of interferon-gamma (IFN-γ), C-X-C motif ligand 1 (CXCL1), tumor necrosis factor-alpha (TNF-α), chemokine ligand 2 (CCL2), interleukin-12p70 (IL-12p70), chemokine ligand 5 (CCL5), interleukin-1β (IL-1β), chemokine (C-X-C motif) ligand 10 (CXCL10), granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-10 (IL-10), interferon-beta (IFN-β), interferon-alpha (IFN-α), and interleukin-6 (IL-6). According to the results of mass spectrometry and network pharmacology, we analyzed the mechanism of Dayuanyin in treating acute lung injury caused by H1N1. The protein levels of extracellular signal-regulated kinase 1/2 (ERK1/2), p38 mitogen-activated protein kinase (p38 MAPK), nuclear factor-kappa B (NF-κB), and their phosphorylated forms were determined by Western blot. The mRNA levels of myeloid differentiation factor 88 (MyD88), Toll-like receptor 3 (TLR3), Toll-like receptor 7 (TLR7), and Toll-like receptor 8 (TLR8) in the lung tissue were measured by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultA total of 57 compounds, including paeoniflorin and baicalein, were detected in Dayuanyin. Compared with the normal group, the model group showed decreased body weight (P<0.01), lung edema and hemorrhage, increased lung index (P<0.01), and elevated levels of IFN-γ, IL-12p70, CCL5, IL-1β, CXCL10, GM-CSF, IFN-β, and IL-6 (P<0.01). Compared with the model group, Dayuanyin attenuated alveolar wall thickening, capillary congestion, and immune cell infiltration, reduced the alterations in body weight and lung index (P<0.01), and down-regulated the protein levels of IFN-γ, IL-12p70, CCL5, IL-1β, CXCL10, GM-CSF, IFN-β, and IL-6 (P<0.01). A total of 57 key genes were predicted by network pharmacological analysis, of which the MAPK signaling pathway was the main target signaling pathway. Compared with the normal group, the model group showed up-regulation in the protein levels of phosphorylation (p)-ERK1/2, p-p38 MAPK, and p-NF-κB (P<0.01) and the mRNA levels of TLR7, TLR8, MyD88, and TLR3 (P<0.05, P<0.01). Compared with the model group, Dayuanyin lowered the phosphorylation levels of ERK1/2, p38 MAPK, and NF-κB p65 in a dose-dependent manner (P<0.01) and down-regulated the mRNA levels of TLR3, TLR7, TLR8, and MyD88 (P<0.01). ConclusionDayuanyin can prevent and control H1N1 infection-induced acute lung injury by inhibiting the TLR/MAPK/NF-κB signaling pathway.

Objective:To explore the specific role and molecular mechanism of octamer-binding transcription factor 4 (Oct4) in promoting the progression of esophageal squamous cell carcinoma and radioresistance.Methods:The Gene Expression Profile Data Dynamic Analysis (GEPIA) database was used to analyze the expression differences of the Oct4 gene in different types of tumor tissues and their corresponding adjacent normal tissues. The clinical data and surgical resection tissue specimens of 196 patients with esophageal squamous cell carcinoma who received surgery combined with radiotherapy at Henan Provincial Chest Hospital from January 2013 to May 2022 were collected. Immunohistochemistry was used to detect the expression of Oct4 protein in the tumor and adjacent tissues. The lentiviral packaging system was used to construct esophageal squamous cell carcinoma cell lines that up-regulated or down-regulated Oct4. The cell counting kit 8 (CCK-8) was used to detect the cell proliferation ability, the scratch test was used to detect the cell migration ability, and the clone formation test was used to detect the cell radiosensitivity. Immunofluorescence experiment was used to detect DNA damage level, and Western blot was used to detect the expressions of Oct4, human phosphorylated histone (γ-H2AX), E-cadherin, N-cadherin, vimentin, and zinc finger E box binding homology box 1 (ZEB1).Results:The analysis of GEPIA database showed that the expression level of Oct4 mRNA in esophageal carcinoma was higher than that in paracancerous tissues. The expression level of Oct4 protein in tumor tissues was 78.35±1.42, which was higher than that in adjacent tissues (16.27±0.49). The survival time of patients with a high expression of Oct4 was significantly shorter than that of patients with a low expression of Oct4 (25.40 and 47.00 months). Compared with the control group, the proliferation ability of KYSE510 cells in the Oct4 up-regulated group was enhanced after 72-h culture, and the cell migration ability of these cells was also enhanced, with the migration rate being (41.67±1.20)% vs (23.67±1.86)% after 24-h culture. The radiosensitivity of cells in this group decreased, with the radiosensitivity enhancement ratio being 0.69±0.06 vs 1.00±0.02. After radiotherapy, the expressions of γ-H2AX and E-cadherin decreased, while the expressions of ZEB1, vimentin and N-cadherin increased. Compared with the control group, the proliferation ability of KYSE150 cells in the Oct4 down-regulated groups 1 and 2 decreased (absorbance being 2.51±0.17, 2.38±0.16, and 3.33±0.07, respectively, P<0.01) after 72-h culture, and the migration ability also decreased, with the migration rate being (13.33±0.88)%, (13.00±1.00)%, and (40.33±2.03)%, respectively (all P<0.001), after 24-h culture. The radiosensitivity was enhanced, with the radiosensitivity enhancement ratio being 1.34±0.11,1.24±0.07, and 1.00±0.02, respectively (all P<0.05). After radiotherapy, the expressions of γ-H2AX and E-cadherin increased, while the expressions of ZEB1, vimentin and N-cadherin decreased. Compared with the control group, the proliferation ability of KYSE510 cells in the ZEB1 down-regulated group decreased [absorbance being 1.33±0.15 vs 1.81±0.16 ( P=0.002)] after 72-h culture. The radiosensitivity was enhanced, with the radiosensitivity enhancement ratio being 1.37±0.11 vs 1.00±0.01 ( P=0.037), and after radiotherapy the expression of γ-H2AX increased. Conclusion:Oct4 is involved in the regulation of epithelial-mesenchymal transformation of esophageal squamous cell carcinoma, which promotes the proliferation, migration, and radioresistance of esophageal squamous cell carcinoma.

Background/Aims:
Ubiquitination is widely involved in the progression of hepatocellular carcinoma (HCC) by regulating various cellular processes. However, systematic strategies for screening core ubiquitin-related genes, clarifying their functions and mechanisms, and ultimately developing potential therapeutics for patients with HCC are still lacking.
Methods:
Cox and LASSO regression analyses were performed to construct a ubiquitin-related gene prediction model for HCC. Loss- and gain-of-function studies, transcriptomic and metabolomics analysis were used to explore the function and mechanism of UBE2S on HCC cell glycolysis and growth.
Results:
Based on 1,423 ubiquitin-related genes, a four-gene signature was successfully constructed to evaluate the prognosis of patients with HCC. UBE2S was identified in this signature with the potential to predict the survival of patients with HCC. E2F2 transcriptionally upregulated UBE2S expression by directly binding to its promoter. UBE2S positively regulated glycolysis in a HIF-1α-dependent manner, thus promoting the proliferation of HCC cells. Mechanistically, UBE2S enhanced K11-linkage polyubiquitination at lysine residues 171 and 196 of VHL independent of E3 ligase, thereby indirectly stabilizing HIF-1α protein levels by mediating the degradation of VHL by the proteasome. In particular, the combination of cephalomannine, a small molecule compound that inhibits the expression of UBE2S, and PX-478, an inhibitor of HIF-1α, significantly improved the anti-tumor efficacy.
Conclusions
UBE2S is identified as a key biomarker in HCC among the thousands of ubiquitin-related genes and promotes glycolysis by E3 enzyme-independent ubiquitination, thus serving as a therapeutic target for the treatment of HCC.

Background:
The incidence density of metabolic dysfunction-associated fatty liver disease (MAFLD) and the effect of a healthy lifestyle on the risk of MAFLD remain unknown. We evaluated the prevalence and incidence density of MAFLD and investigated the association between healthy lifestyle and the risk of MAFLD.
Methods:
A cross-sectional analysis was conducted on 37,422 participants to explore the prevalence of MAFLD. A cohort analysis of 18,964 individuals was conducted to identify the incidence of MAFLD, as well as the association between healthy lifestyle and MAFLD. Cox proportional hazards regression was used to calculate the hazard ratio (HR) and 95% confidence interval (CI) with adjustments for confounding factors.
Results:
The prevalence of MAFLD, non-alcoholic fatty liver disease, and their comorbidities were 30.38%, 28.09%, and 26.13%, respectively. After approximately 70 thousand person-years of follow-up, the incidence densities of the three conditions were 61.03, 55.49, and 51.64 per 1,000 person-years, respectively. Adherence to an overall healthy lifestyle was associated with a 19% decreased risk of MAFLD (HR, 0.81; 95% CI, 0.72 to 0.92), and the effects were modified by baseline age, sex, and body mass index (BMI). Subgroup analyses revealed that younger participants, men, and those with a lower BMI experienced more significant beneficial effects from healthy lifestyle.
Conclusion
Our results highlight the beneficial effect of adherence to a healthy lifestyle on the prevention of MAFLD. Health management for improving dietary intake, physical activity, and smoking and drinking habits are critical to improving MAFLD.
