Background: Cancer stem cells (CSCs) are highly tumorigenic, chemotherapy-resistant, tumor growth-sustaining, and implicated in recurrence.Previous studies have shown that lysine-specific histone demethylase 1A (KDM1A) is expressed several human malignancies CSCs.However, the role of KDM1A CSCs therapeutic potential inhibitors for treatment advanced thyroid cancer poorly understood.Methods: Firstly, was identified as an important epigenetic modifier maintained stemness through a mini...

Abstract Homologous recombination-mediated genome engineering has been broadly applied in prokaryotes with high efficiency and accuracy. However, this method is limited realizing larger-scale editing numerous genes or large DNA fragments because of the relatively complicated procedure for template construction. Here, we describe a CRISPR-Cas9 assisted non-homologous end-joining (CA-NHEJ) strategy rapid efficient inactivation bacterial gene (s) homologous recombination-independent manner...

Abstract Background Benzo[a]pyrene (B[a]P), a carcinogen pollutant produced by combustion processes, is present in the western diet with grilled meats. Chronic exposure of B[a]P hepatocellular carcinoma (HCC) cells promotes metastasis rather than primary proliferation, implying an unknown mechanism B[a]P‐induced malignancy. Given that exosomes carry bioactive molecules to distant sites, we investigated whether and how mediate cancer‐stroma communications for toxicologically associated...

Abstract Direct optimization of the metabolic pathways on chromosome requires tools that can fine tune overexpression a desired gene or optimize combination multiple genes. Although plasmid-dependent has been used for this task, fundamental issues concerning its genetic stability and operational repeatability have not addressed. Here, we describe rapid reliable strategy chromosomal integration gene(s) with copies (CIGMC), which uses flippase from yeast 2-μm plasmid. Using green fluorescence...

Background The clinical benefits of antiprogrammed cell death protein 1 (PD-1) therapy are compromised by resistance in immunologically cold tumors. Convergence immunotherapy and bioengineering is potential to overcome the resistance. Mesoporous silica nanoparticles (MSNs) considered most promising inorganic biological nanomaterials for transformation, however, fundamental influence MSNs on unclear. In this study, we aimed investigate role tumor resensitization explore feasibility combined...

Abstract The oxygenic photosynthetic bacterium Synechocystis sp. PCC 6803 (S6803) is a model cyanobacterium widely used for fundamental research and biotechnology applications. Due to its polyploidy, existing methods genome engineering of S6803 require multiple rounds selection modify all copies, which time‐consuming inefficient. In this study, we engineered the Cas9 tool one‐step, segregation‐free engineering. We further our delete three seven native plasmids. Our results show that...

Abstract Modern diets, which often feature high levels of fat and charcoal-grilled meat, contribute to the pathogenesis obesity non-alcoholic fatty liver disease (NAFLD), resulting in cancer progression. Benzo(a)pyrene (B[a]P) is a common environmental foodborne pollutant found smoke fire-grilled foods, can have an adverse effect on human health. Hepatocellular carcinoma (HCC) fifth leading cause second cancer-related deaths worldwide. The epidemiological studies suggest that both risk...

Deep learning methods have demonstrated strong performance in objection tasks; however, their ability to learn domain-specific applications with limited training data remains a significant challenge. Transfer techniques address this issue by leveraging knowledge from pre-training on related datasets, enabling faster and more efficient for new tasks. Finding the right dataset can play critical role determining success of transfer overall model performance. In paper, we investigate impact...
