Sanguinarine suppresses oral squamous cell carcinoma progression by targeting the PKM2/TFEB aix to inhibit autophagic flux.

Background: Oral squamous cell carcinoma (OSCC) is one of the most common malignancies. However, there is no effective treatment for OSCC.

Purpose: This study aimed to identify a natural compound with significant efficacy against OSCC and elucidate its primary mechanism of action.

Radiofrequency radiation reshapes tumor immune microenvironment into antitumor phenotype in pulmonary metastatic melanoma by inducing active transformation of tumor-infiltrating CD8 T and NK cells.

Immunosuppression by the tumor microenvironment is a pivotal factor contributing to tumor progression and immunotherapy resistance. Priming the tumor immune microenvironment (TIME) has emerged as a promising strategy for improving the efficacy of cancer immunotherapy. In this study we investigated the effects of noninvasive radiofrequency radiation (RFR) exposure on tumor progression and TIME phenotype, as well as the antitumor potential of PD-1 blockage in a model of pulmonary metastatic melanoma (PMM).

Cadmium Exposure is Associated with the Prevalence of Dyslipidemia.

Background: Cadmium is a widespread environmental and occupational pollutant that accumulates in human body with a biological half-life exceeding 10 years. Cadmium exposure has been demonstrated to increase rates of cardiovascular diseases. Whether occupational cadmium exposure is associated with the increase in the prevalence of dyslipidemia and hence contributes to the risk of cardiovascular diseases is still equivocal.

NiO nanoparticles induce apoptosis through repressing SIRT1 in human bronchial epithelial cells.

With application of nano-sized nickel-containing particles (Nano-Ni) expanding, the health concerns about their adverse effects on the pulmonary system are increasing. However, the mechanisms for the pulmonary toxicity of these materials remain unclear. In the present study, we focused on the impacts of NiO nanoparticles (NiONPs) on sirtuin1 (SIRT1), a NAD-dependent deacetylase, and investigated whether SIRT1 was involved in NiONPs-induced apoptosis.

[Expression and roles of the epithelial mesenchymal transition markers E-cadherin and vimentin in hepatocellular carcinoma].

Objective: To determine the differential protein expressions of epithelial mesenchymal transition (EMT) markers E-cadherin and vimentin in hepatocellular carcinorma (HCC) and to investigate their correlation to the molecular mechanisms of metastasis to explore their potential utility as prognostic indicators of HCC.

Methods: Tumor tissues and patient-matched adjacent non-tumor tissues were collected from individuals diagnosed with HCC. E-cadherin and vimentin protein expressions in the tissue specimens were quantified by western blot with densitometry of fluorescence emission and comparatively analyzed to determine the associations with molecular and clinical features.

Damage to mtDNA in liver injury of patients with extrahepatic cholestasis: the protective effects of mitochondrial transcription factor A.

Oxidative stress and mitochondrial dysfunction are involved in the pathogenesis of chronic liver cholestasis. Mitochondrial DNA (mtDNA) is highly susceptible to oxidative stress and mtDNA damage leads to mitochondrial dysfunction. This study aimed to investigate the mtDNA alterations that occurred during liver injury in patients with extrahepatic cholestasis.
