Anthraquinone from Edible Fungi Pleurotus ostreatus Protects Human SH-SY5Y Neuroblastoma Cells Against 6-Hydroxydopamine-Induced Cell Death-Preclinical Validation of Gene Knockout Possibilities of PARK7, PINK1, and SNCA1 Using CRISPR SpCas9.

Parkinson's disease (PD) results from the degeneration of the nervous tissue brought about by ecological and hereditary components which affects nerve cells in the brain. It is the world's second most normal neurodegenerative issue, which can essentially weaken the personal satisfaction, make reliance, and trigger untimely mortality of affected people. The commonness pace of PD is 0.5-1% among individuals in the age group of 65-69 years and 1-3% among those 80 or more. Clinical appearances incorporate bradykinesia, tremors, unbending nature, and postural unsteadiness; spectrums of non-motor symptoms include psychological hindrance and passionate and behavioral brokenness. In this study, 6-OHDA-induced neurotoxicity was analyzed for various cytotoxicity analyses. The genes identified were PINK1 (PTEN-induced kinase 1), PARK7 (Parkinsonism-associated deglycase) and SNCA 1 (alpha synuclein1) validated using CRISPR spcas9 genome editing tool. In this study, Anthraquinone isolated from Pleurotus ostreatus was treated against a dopaminergic neurotoxin, 6-hydroxydopamine (6-OHDA), which induced neurotoxicity in SH-SY5Y cells. Experimental groups in SH-SY5Y neuroblastoma cells were treated with anthraquinone (50 nM) and 6-OHDA (100 nM). MTT and ROS assays were performed to assess the cell viability and oxidative stress within the cells, followed by mixed-member proportional (Mitochondrial membrane potential), dual staining, and immunoblotting. 6-OHDA-induced cell death in SH-SY5Y cells was dose-dependently attenuated by treatment with anthraquinone. The genes responsible for mutation were studied and the mutated RNAs knockout possibilities was studied using CRISPR spcas9 genome editing tool. Treatment with anthraquinone attenuated the level of oxidative stress and reduced the mitochondrial dysfunction associated with 6-OHDA treatment. Immunoblot analysis carried out with apoptotic markers showed that cytochrome C and caspase-3 expression increased significantly in anthraquinone-treated cells, whereas 6-OHDA-treated group showed a significant decrease when compared with an experimental control group. The mutated genes PARK7, PINK1, and SNCA1 were analyzed and found to exhibit four gene knock possibilities to treat PD. Reports demonstrate that other than following up on the biosynthesis of dopamine and its metabolites, these mixes counteract D2 receptors' extreme touchiness. It is proposed that further examinations need be directed to better understand the activity of the bioactive mixes circulated in these edible fungi Pleurotus ostreatus. The gene knockout possibilities identified by CRISPR SpCas9 will pave a way for better research for PD treatment.

Protective effect of Averrhoa bilimbi L. fruit extract on ulcerative colitis in wistar rats via regulation of inflammatory mediators and cytokines.

Ulcerative Colitis (UC) is a lingering type of Inflammatory Bowel Disease (IBD) which affects the colon mucosa. Ulcerative colitis is majorly associated with oxidative stress and inflammation in colon tissue leading to damage. Averrhoa bilimbi L. fruit is rich in antioxidant phytochemicals including Vitamin C. In the current research, we have evaluated the defence mechanism of Averrhoa bilimbi L. on Ulcerative Colitis (UC). Male wistar rats were treated with Averrhoa bilimbi L. fruit extract (50mg/kg/bwt and 100mg/kg/bwt) and a standard drug Sulfasalazine (100mg/kg/bwt) for 6 consecutive days via intra peritoneally. After one day fasting, rats were given single dose of 3% 2ml of acetic acid through anal (intra-anal) region to induce Ulcerative Colitis. The protective and therapeutic effect of fruit extract on UC was assessed by comparing the relevant changes observed in the normal and treated group. In treated group the level of mucosal injury was decreased (ulcer score - 2) when compared to the control group (ulcer score - 9). The abnormal increase observed in the inflammation mediator cytokines in control rats, i.e IL-1ß, IL-6, TNF-α levels were decreased significantly (**p<0.01) in the Averrhoa bilimbi L. fruit extract treated groups. The increase in weights of the colon tissue and spleen of the control rats were found to be reduced in treated groups. The levels of inflammatory markers iNOS and COX-2 were also decreased in treated group significantly (**p<0.01) when compared with the control. Furthermore, the treatment with Averrhoa bilimbi L. fruit extract has shown a significant antioxidant activity in the UC condition by reducing the levels of NO and enhancing the levels of SOD and GSH in the colon tissue. These results demonstrate the effective anti-ulcerative colitis activity of the Averrhoa bilimbi L. fruit extract in experimental wistar rats.

Acacia ferruginea inhibits cyclophosphamide-induced immunosuppression and urotoxicity by modulating cytokines in mice.

Cyclophosphamide (CTX), commonly used as an anti-neoplastic drug, can cause adverse side-effects including immunotoxicity and urotoxicity. Increasingly, plants have become sources of therapeutics that can help to restore host immunity to normal. In this study, Acacia ferruginea was assessed for an ability to protect mice against/mitigate CTX-induced toxicity. Co-administration of an extract of A. ferruginea (10 mg/kg BW, IP daily) for 10 consecutive days reduced CTX (25 mg/kg BW, IP daily)-induced toxicity. Apart from improvements in bladder and small intestine morphology, there was marked improvement in anti-oxidant (glutathione) levels in the bladder, suggesting a role for the anti-oxidant in reducing CTX-induced urotoxicity. Moreover, use of the extract significantly increased total leukocyte counts and bone marrow cellularity/α-esterase activity in CTX-treated mice which suggested a protective effect on the hematopoietic system. Co-treatment with the extract also prevented decreases in organ (liver, kidney, spleen, thymus) weight as well as body weight, thereby seemingly lessening the potential impact of CTX on the host immune system. Further, CTX-induced increases in serum aspartate transanimase, alanine transaminase, and alkaline phosphatase were reversed by extract co-treatment, as were alterations in in situ formation/release of interferon (IFN)-γ, interleukin (IL)-2, granulocyte-macrophage colony stimulating factor (GM-CSF), and tumor necrosis factor (TNF)-α. Overall, this study indicated there were some protective effects from use of an extract of A. ferruginea against CTX-induced toxicities, in part through modulation of levels of anti-oxidants and pro-inflammatory cytokines.

Modulating effect of Biophytum sensitivum extract on rats with acetic acid-induced ulcerative colitis.

CONTEXT: Traditionally, Biophytum sensitivum (L.) DC (Oxalidaceae) is used in Indian medicine to treat diseases include stomachache, convulsions, cramps, inflammation, and ulcer. OBJECTIVE: The present study examines the effect of aerial parts of B. sensitivum (methanol extract) on a murine model of ulcerative colitis (UC). MATERIALS AND METHODS: UC was induced by intracolonic injection of 3% acetic acid in Wistar rats. B. sensitivum (50 or 100 mg/kg b wt) or reference drug sulfasalazine (100 mg/kg b wt) was administrated intra-peritoneally for 5 consecutive days before induction of colitis. RESULTS: In the present study, we demonstrated for the first time that the administration of B. sensitivum (50 mg/kg b wt) was found to inhibit colitis by lowering macroscopic score (up to 3.66 ± 0.77) and also showed significant reduction (p < 0.01) in lactate dehydrogenase (LDH) and myeloperoxidase (MPO) activities. Furthermore, a significant reduction (p < 0.01) in mucosal content of lipid peroxidation (LPO), glutathione (GSH), superoxide dismutase (SOD), and nitric oxide (NO) confirms that B. sensitivum could significantly inhibit colitis. The study showed significant reduction (p < 0.01) in colonic tumor necrosis factor-α (TNF-α), interleukin-1-ß (IL-1ß), and IL-6 levels as well as the expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) after treatment compared with the colitis control group. The histopathological study also confirms the foregoing findings. Treatment with B. sensitivum was also able to inhibit the activation and translocation of transcription factors, nuclear factor (NF)-κB subunits (p65/p50). CONCLUSION: These results suggest that B. sensitivum exhibits protective effect against acetic acid-induced UC.

Amentoflavone inhibits iNOS, COX-2 expression and modulates cytokine profile, NF-κB signal transduction pathways in rats with ulcerative colitis.

Ulcerative colitis is a chronic inflammatory disorder characterized by oxidative stress, leucocyte infiltration and upregulation of pro-inflammatory cytokines. The aim of the present study was to examine the effect of amentoflavone on a murine model of ulcerative colitis (UC). UC was induced by intracolonic injection of 3% acetic acid in male Wistar rats. amentoflavone (10 mg/kg·b.wt) or reference drug sulfasalazine (100 mg/kg·b.wt) was administrated intra-peritoneally for 5 consecutive days before induction of colitis with acetic acid. Administration of amentoflavone was found to reduce the extent of inflammatory colonic injury. This was manifested by a decrease in the score of mucosal injury, by lowered colonic wet weight as well as vascular permeability and diminished lactate dehydrogenase (LDH) and myeloperoxidase (MPO) activity reflecting reduced leukocyte infiltration. Furthermore, the mucosal content of lipid peroxidation (LPO), glutathione (GSH), superoxide dismutase (SOD), nitric oxide (NO) activity confirms that amentoflavone could significantly inhibit colitis. The treatment also reduced significantly the colonic tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1ß) and IL-6 levels as well as the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) compared to colitis control group. The histopathological studies also confirm the foregoing findings. amentoflavone was also able to inhibit the activation and translocation of transcription factors, nuclear factor (NF)-κB subunits (p65/p50). These results suggest that amentoflavone exhibits protective effect in acetic acid-induced ulcerative colitis which might be due to its modulation of oxidant/anti-oxidant balance, down-regulation of productions and expressions of pro-inflammatory cytokines, inflammatory mediators and inhibition of NF-κB signal transduction pathways.

Anticancer activity of Acacia nilotica (L.) Wild. Ex. Delile subsp. indica against Dalton's ascitic lymphoma induced solid and ascitic tumor model.

The aim of the present investigation was to evaluate the effect of A. nilotica extract against Dalton's ascitic lymphoma (DAL) induced solid and ascitic tumors in BALB/c mice. Experimental animals received A. nilotica extract (10 mg/kg.bw) intraperitoneally for 10 and 14 consecutive days before induction of solid and ascitic tumors, respectively. Treatment with A. nilotica extract significantly decreased the development of tumor and percentage increase in body weight when compared to DAL induced solid tumor control group, also increasing the life span, restoring the total white blood cell count and hemoglobin content and significantly decreasing the levels of serum aspartate transaminase (SGPT), alanine transaminase (SGOT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and nitric oxide (NO) when compared to DAL induced ascitic tumor controls. The treatment also reduced significantly the cellular glutathione (GSH) and nitric oxide levels in treated animals. Histopathological studies also confirmed protective influence. The outcome of the present work indicates that A. nilotica extract could be used as natural anticancer agent for human health.

WAVEs: a novel and promising weapon in the cancer therapy tool box.

The Wiskott-Aldrich Syndrome Protein family Verprolin--homologous proteins (WAVEs), encoded by a metastasis promoter gene, play considerable roles in adhesion of immune cells, cell proliferation, migration and destruction of foreign agents by reactive oxygen species. These diverse functions have lead to the hypothesis that WAVE proteins have multi-functional roles in regulating cancer invasiveness, metastasis, development of tumor vasculature and angiogenesis. Differentials in expression of WAVE proteins are associated with a number of neoplasms include colorectal cancer, hepatocellular cancer, lung squamous cell carcinoma, human breast adenocarcinoma and prostate cancer. In this review we attempt to unify our knowledge regarding WAVE proteins, focusing on their potentials as diagnostic markers and molecular targets for cancer therapy.
