The protoplast-based transient gene expression system is a powerful tool for gene functional characterization and CRISPR/Cas9 genome editing in higher plants, but it has not been widely used in citrus. In this study, the polyethylene glycol(PEG)-mediated method was optimized for citrus callus protoplast transfection, with an improved transfection efficiency of 68.4%. Consequently, the efficiency of protein subcellular localization assay was increased to 65.8%, through transient expression of the target gene in protoplasts that stably express the fluorescent organelle marker protein. The gene editing frequencies in citrus callus protoplasts reached 14.2% after transient expression of CRISPR/Cas9 constructs. We demonstrated that the intronic polycistronic tRNAgRNA(inPTG) genome editing construct was functional in both the protoplast transient expression system and epicotyl stable transformation system in citrus. With this optimized protoplast transient expression system, we improved the efficiency of protein subcellular localization assay and developed the genome editing system in callus protoplasts, which provides an approach for prompt test of CRISPR vectors.展开更多

Here we explored the tumor inhibition effects of Ganoderma lucidum(G. lucidum) on oral squamous cell carcinoma(OSCC). Specifically, we aimed to clarify the biological mechanism of components in the dietary, aqueous-soluble sporoderm-removed G. lucidum spore powder(A-GSP).Methods: Preliminary transcriptome analysis revealed the significant enrichment of the ferroptosis pathway.Cellular Fe2+, glutathione(GSH), malondialdehyde(MDA), reactive oxygen species(ROS) and lipid peroxide levels were measured to identify ferroptosis occurrence. Western blotting was used to measure ferroptosis-related proteins. Changes in mitochondria morphology and function were observed with transmission electron microscopy(TEM) and ATP detection assays. Ferroptosis inhibitor ferrostatin-1 was then used to verify the anti-tumor effects of A-GSP. Finally, nude mice xenograft models of oral cancer confirmed that A-GSP inhibited tumor growth.Results: A-GSP promoted ferroptosis in oral cancer cells by inducing Fe2+influx, GSH depletion, as well as lipid peroxide and ROS accumulation. Ferroptosis-related proteins exhibited corresponding changes, particularly Acylco A synthetase long chain family member 4(ACSL4) increase and glutathione peroxidase 4(GPX4) decrease. A-GSP considerably lowered mitochondrial volume and ridge number, while significantly decreasing ATP production. Ferrostatin-1 reversed all of these A-GSP-induced changes. In vivo, A-GSP exerted a ferroptosismediated tumor-suppressing effect without observable adverse reactions.Conclusions: Our findings demonstrate the therapeutic potential of A-GSP for treating patients with OSCC by targeting ferroptosis.展开更多

Material and Methods: 64 Wistar rats were used in 4 groups: one control, three experimental, streptozotocin, Kombucha y Ganoderma induced diabetes with streptozotocin. Divided into four post-induction stages at 2, 15, 30 and 45 days of treatment, sacrificing 4 rats at each stage, to perform the morphological analysis of the pancreas. Results: A decrease in the islets of Langerhans in size, volume and the number of cells within them was identified for the streptozotocin group from the second stage until almost disappearing due to diabetes, in the groups of Kombucha y Ganoderma the same was observed but they were recovered with the extract treatments and the average number of islets was similar in these groups, the group of Ganoderma. Conclusion: Under the conditions of this work, a protective and regenerative effect of both extracts is identified.展开更多
