The aim of the present study was to explore the anti-breast cancer activity of the plant I. turpethum together with the comparative analysis of the cytotoxicity of the extracts from different parts of the plant. The gas chromatography-mass spectrometry (GC-MS) analysis of the plant revealed the identification of 71 compounds. The cytotoxicity of the extracts from different parts (whole, aerial, and root) of the plant was evaluated against the breast cancer cell lines (MCF-7 and MDA MB-231) by 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase (LDH) assays. The findings of these assays were further confirmed by the carboxyfluorescein diacetate succinimidyl ester (CFSE) proliferation assay, DAPI (4',6-diamidino-2-phenylindole) nuclear staining, and simple microscopy images. The results of the MTT assay revealed that the root extract showed the lowest IC50 values, i.e., 516 μg/mL for MCF-7 and 396 μg/mL for MDA MB-231 cell lines. The LDH release in the medium was high in the root extract treated cells, i.e., 28.87% for MCF-7 and 23.62% for MDA MB-231 cell lines. Moreover, the CFSE proliferation assay also showed the decrease in the proliferation of the cells up to 48.7% and 46.4% in case of MCF-7 and MDA MB-231 cells, respectively. The fragmented and condensed nuclear material in both the cell lines was observed in the DAPI nuclear staining. In conclusion, results showed that the root extract possess the highest cytotoxicity among all other tested extracts toward both breast cancer cell lines (MCF-7 and MDA MB-231).Colon cancer (CC) is the most common type of gastrointestinal cancer and is the third leading cause of cancer patient's death worldwide. Long non-coding RNAs (lncRNAs) are important regulatory molecules involved in various cellular processes, and many of them are shown as significant prognosis biomarkers of malignant tumors. In the present study, we identified differentially expressed lncRNAs between CC and adjacent normal tissues based on two TCGA database (GEPIA and circlncRNAnet). Over 1500 differentially expressed lncRNAs between CC and adjacent normal tissues were obtained based on these two websites, and 72 lncRNAs (FC > = 2, Log2 (TPM+1) > 1, P less then 0.05) were chosen for further analysis. Seventeen of them were CC specific-expressed lncRNAs. We then evaluated the expression of the 17 lncRNAs in diverse tumor stage. LncRNA double homeobox A pseudogene 8 (DUXAP8), RP11-54H7.4, and RP11-138J23.1 showed higher expression in later tumor stages. Built on survival analysis, we found that high expression of DUXAP8 and ELFN1 antisense RNA 1 (ELFN1-AS1) predicts poor prognosis in CC. In addition, high expression of the 17 lncRNAs set predicts poor prognosis in CC. This study provides a new way to evaluate the prognosis of CC.Diabetes and tobacco use are two of the largest public health challenges of our time. We aim to investigate the association between the two by comparing biochemical profiles of diabetic tobacco users (TUs) and tobacco nonus-ers (TNUs) to provide insight into the joint effect of tobacco and diabetes on body systems. This case-controlled study included 265 subjects, aged 18-60 yr, from the suburban population of Delhi, India. With the help of a questionnaire, participants are interviewed regarding their history of tobacco use. Results show association of tobacco use with elevated body-mass index, blood glucose levels, and insulin resistance in otherwise healthy and diabetic TUs. Even without previous history of coronary heart disease, total cholesterol and triglycerides are significantly further increased in TUs rather than in TNUs, indicative of initiation of lipid metabolism disorders. Tobacco use is also seen as a cause of oxidant/antioxidant imbalance in the body. Low serum albumin coupled with increased markers of inflammation and globulin levels is an indicator of generalized inflammation caused by tobacco's toxic effects. Creatinine levels are significantly higher in diabetic TUs, posing a threat to nephropathy progression. Evidence sufficiently infers that tobacco activates multiple biological pathways, through which the risk of metabolic disease increases. These factors may work in conjunction to increase risk of certain microvascular and macrovascular complications.Breast cancer is a widespread disease that affects women globally. Diagnostic processes and remedial approaches to breast carcinogenesis have improved in recent decades, but continuous survival of patients with breast carcinogenesis is still lacking due to increased cell proliferation. Staurosporine The aim of the present work is to explore the anticell proliferative effects of nobiletin (NOB) against 7,12-dimethylbenz[a]anthracene (DMBA)-treated mammary tumorigenesis in rats. We stimulate mammary carcinogenesis using oral gavage of DMBA (25 mg/kg body weight) mixed with olive oil (1 mL). This results in reduced body weight; increased liver marker enzymes such as alkaline phosphatase, acid phosphatase, aspartate aminotransferase, and alanine aminotransferase; and cell proliferative markers such as c-Jun, proliferating cell nuclear antigen, c-Fos, cyclin D1, and activating protein-1 (AP-1) in the DMBA-treated cancer-bearing animals. NOB administration improved body weight, significantly reduced hepatic marker enzymes, and altered histopathological changes. Furthermore, NOB efficiently reduced tumor cell proliferation markers in DMBA-induced mammary carcinogenesis. Overall, these results suggest that NOB has an anticell proliferative effect on DMBA-induced mammary cancer via modulation of the AP-1 signaling pathway.Glutamatergic N-methyl-D-aspartate (NMDA) receptors have critical roles in several neurological and psychiatric diseases. Dizocilpine (MK-801) is a ligand at phencyclidine recognition sites that is associated with NMDA receptor-coupled cation channels, where it acts as a potent noncompetitive antagonist of central glutamate receptors. In this study, we investigate the effect of clozapine on MK-801-induced neurochemical and neurobehavioral alterations in the prefrontal cortex of mice. Acute administration of NMDA noncompetitive antagonist MK-801 impairs motor coordination, grip strength, and locomotor activity. Clozapine is the only medication that is indicated for treating refractory schizophrenia, due to its superior efficacy among all antipsychotic agents; however, its mechanism is not well understood. To understand its mechanism, we investigated the effects of clozapine on motor coordination, locomotor activity, and grip strength in mice against the NMDA receptor antagonist MK-801. MK-801 induced elevations in acetylcholinesterase (AChE) activity, monoamine oxidase (MAO) activity, and c-fos expression. The administration of clozapine inhibited the effects caused by MK-801 (0.2 mg/kg body weight). Motor coordination and grip strength paradigms that had been altered by MK-801 were restored by clozapine. Moreover, clozapine also ameliorated MK-801-induced elevation in AChE and MAO activity. Our immunostaining results demonstrated that clozapine treatment reduced overexpression of the neuronal activity marker c-fos in cortices of the brain. Results of the current study determine that clozapine ameliorated cognition in MK-801-treated mice via cholinergic and neural mechanisms. These findings show that clozapine possesses the potential to augment cognition in diseases such as schizophrenia.Melanoma is among the most aggressive and treatment-resistant human cancers. Phellinus baumii, a famous medicinal mushroom, has been used to treat different diseases, including cancer, in China and other east Asian countries. The purpose of this research was to explore its anticancer effects against melanoma, and the mechanisms that might be involved. CCK-8 assay exhibited that extracts of Ph. baumii (EPB) strongly inhibited cell viability of A375 melanoma cancer cell. Typical morphological changes of cell apoptosis were observed in EPB-treated A375 cells in Hoechst staining assay. Flow cytometry analysis indicated that EPB significantly induced A375 cells apoptosis and the cell cycle was disrupted in S phase. EPB increased the expression of Bax, and decreased Bcl-2 in A375 cells. EPB remarkably caused mitochondrial membrane potential collapse and induced a mitochondrial-dependent apoptosis in A375 cells evidenced by caspase-3 activation, followed by PARP cleavage. More importantly, EPB has shown a strong inhibitory effect on the migration and aggression of the A375 cells through the healing of the wound and transwell assay. In vivo, EPB was also found to strongly inhibit the growth of tumors in BALB/c nude mice. Our results indicated that Ph. baumii might be a natural therapeutic product for aggressive melanoma because it could induce apoptosis and inhibit metastasis in A375 cells.The objective of this study was to explore the effect of magnesium acetate (MA) addition on the endo-polyphenol yield by Phellinus baumii and establish a feasible additive strategy. The optimal three-point MA addition strategy (0.05 g/L concentration of MA added at 0 h and 6 h, 0.9 g/L concentration of MA added at 12 h) was employed to obtain maximum endo-polyphenol yield. The maximum endo-polyphenol production was reached at 1.22 g/L, which was 1.39-fold higher than that of the control. Additionally, the endo-polyphenol showed stronger antioxidant activity in vitro compared with the control, including DPPH· scavenging capacity (78.76%) and Trolox equivalent antioxidant capacity (TEAC) (32.28 μmol Trolox/g sample). HPLC analysis showed that the endo-polyphenol production of the crude ethanol extracts was significantly higher than that of the control. Hispidin was isolated and identified from the ethanol extract of the culture mycelia from Ph. baumii with the three-point MA addition strategy. Hispidin showed a strong ability to scavenge DPPH free radicals and TEAC, equivalent to positive (vitamin C) value of 89.41% and 75.98%, respectively. Furthermore, hispidin protected H2O2-induced PC12 cells injured by decreased oxidative stress level. These results indicated that the MA multi-stage addition strategy was dependable, and could be used to develop new natural antioxidants for foods or medicines.Ergothioneine is a natural 2-thiol-amidazole amino acid that plays an important role in inflammation, depression, and cardiovascular disease. Flammulina velutipes is a common basidiomycete mushroom rich in ergothioneine (EGT). However, the biosynthetic pathway of EGT in F. velutipes is still unclear. In this study, the F. velutipes ergothioneine biosynthetic gene 1 (Fvegtl), F. velutipes ergothioneine biosynthetic gene 2 (Fvegt2), and F. velutipes ergothioneine biosynthetic gene 3 (Fvegt3) were cloned and expressed, and the activities of the proteins encoded by these three genes (FvEgt1, F. velutipes ergothioneine biosynthase 1; FvEgt2, F. velutipes ergothioneine biosynthase 2; and FvEgt3, F. velutipes ergothioneine biosynthase 3) were identified. The results showed that FvEgtl not only has the function of methyltransferase, but also has the function of hercynlcysteineteine sulfoxide (Hersul) synthase, which can catalyze the production of Hersul from histidine and cysteine in F. velutipes. FvEgt2 and FvEgt3 are two functionally different cysteine desulfurase enzymes.
