The current study examined the prevalence of Eimeria infections in domestic rabbits in China. A total of 480 faecal samples were collected from 48 farms in 14 provinces of China. Each faecal sample was subjected to oocyst counting and oocyst isolation. The Eimeria species from samples containing isolated and sporulated oocysts were morphologically identified under microscope. The overall prevalence of infections was 41.9% (201/480). Northwest China had the highest prevalence (70%), followed closely by Northeast China (65%) and Southwest China (62.5%). The prevalences in North China (34%) and South China (25.8%) were significantly lower. The large and medium farms had lower prevalences (34.2% and 37.2%, respectively) than the small farms (61.4%). Coccidian oocysts were found in 42.2% (76/180) of faecal samples from meat rabbits, 40% (28/70) from angora rabbits and 44.7% (85/190) from Rex rabbit. In total, ten species of Eimeria were identified from oocyst-positive samples. Concurrent infection with two to eight Eimeria species was found. E. perforans was the most prevalent species (35.2%), followed in order by E. media, E. magna, E. irresidua and E. intestinalis with prevalences of 31.3%, 28.8%, 19.4%, and 14.8%, respectively. Taken together, These results reveal the characteristics of the prevelance of rabbit coccidia infection in China, including the distribution, the scale of farming and the species, which are indispensable to the control of rabbits coccidiosis in China.

Background: Present investigation evaluates the antitumor activity of epifriedelinol for the management of cervical cancer by inducing process of apoptosis. Methods: Human Cervical Cancer Cell Line, C33A and HeLa were selected for study and treated with epifriedelinol at a concentration of (50-1000 µg/ml). Cytotoxicity of epifriedelinol was estimated by MTT assay and induction of apoptosis was assessed by estimating the activity of caspase 3, 8 and 9 enzyme, apoptosis assay and translocation of cytochrome c. Moreover an expression of several proteins that plays role in the apoptosis process was estimated by western blot method. Results: Result of the study suggested that treatment with epifriedelinol significantly decrease the viability count of cancerous cell in a dose perndent manner and also enhances the formation of oligonucleosome in both the cell lines. However activity of caspase enzymes and translocation of cytochrome c were enhanced after treatment with epifriedelinol. It was also observed that epifriedelinol treatment alters the ratio of pro-apoptotic to anti-apoptotic proteins and enhances the expressions of inhibitor of apoptosis proteins (IAP). Conclusion: Result of our study proves the anticancer activity of epifriedelinol in cervical cancer by inducing apoptosis as treatment with it enhances the production of oligonucleosomes, translocation of cytochrome c and activity caspase enzymes.

Dynamin 3 (DNM3) functions as a tumor suppressor in various malignancies. However, the underlying mechanism of DNM3 in cervical cancer remains to be elucidated. The present study aimed to indicate the function of DNM3 in cervical cancer. The expression of DNM3 in cervical tissues and cells was measured using bioinformatics analysis, immunohistochemistry and reverse transcription-quantitative PCR. The pcDNA3.1 plasmid was used to overexpress DNM3 in SiHa and C33A cells. The effects of DNM3 overexpression on cell proliferation, migration, invasion and apoptosis was detected by the CCK-8, clone formation, Transwell, flow cytometry and western blotting assays. In the present study, it was revealed that DNM3 was expressed at significantly low levels in cervical cancer tissues and cell lines compared with normal cervical tissues and cell lines. In addition, the low expression of DNM3 was significantly associated with high pathological grading of cervical cancer. The overall survival rate of patients with low DNM3 expression was significantly improved compared with patients with high DNM3 expression. In addition, the overexpression of DNM3 significantly inhibited the proliferation, migration and invasion of cervical carcinoma cells and induced cell apoptosis. The findings of the present study further revealed that the overexpression of DNM3 may inhibit cell migration and invasion by inactivating the epithelial mesenchymal transition process. In summary, the present study demonstrated that DNM3 was a tumor suppressor in cervical cancer progression and that it may serve as a potential prognostic biomarker for patients with cervical carcinoma.

Purpose: To investigate the anticancer activity of apigenin on human cervical cancer cells. Methods: The anti-proliferative effects of apigenin on HeLa cervical cancer cells were determined by 3-(4,5-dimethylthiazol-2-yl)-)-2,5-diphenyltetrazolium bromide (MTT) and clonogenic assays, while its effect on apoptosis was assayed by DAPI and annexin V/PI double staining. Expression of proteins was assessed by immunoblotting. Results: Apigenin exerted anticancer effects on HeLa cervical cancer cells with an IC50 of 15 µM, and also reduced the colony formation of HeLa cells. These antiproliferative effects were due to induction of apoptosis as indicated by DAPI and annexin V/PI staining. Apigenin altered Bax/Bcl-2 ratio, thereby triggering apoptosis, and also inhibited the Raf/MEK/ERK signalling pathway. Conclusion: These results indicate that apigenin suppresses the growth of cervical cancer cells and may prove to be an important molecule for the treatment of cervical cancer.

The purpose of this study is to investigate the protective effect of gambogenic acid (GA) in acetaminophen (APAP)-induced hepatotoxicity in rat models. GA (10 mg/kg) was administered intraperitoneal (i.p.) to rats for 7 consecutive days followed by APAP (500 mg/kg) single dose (i.p.) on the final day after GA administration. The levels of MDA, GSH, SOD, CAT, GPx, GST, ALP, AST, ALT, proinflammatory cytokines (TNF-α, IL-1β, IL-6), apoptosis markers (caspase-3 and -9, Bax, Bcl-2), 4-hydroxynonenal (4-HNE), and prostaglandin E2 (PGE2) were evaluated. Results exhibited protective effects of GA by inhibiting inflammation, preventing oxidative stress and apoptosis in APAP-induced liver. Histopathological changes caused by APAP were attenuated, protein expressions of phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) were upregulated, and nuclear factor–kappa β (NF-kβ) was downregulated by GA. In summary, GA significantly exerted anti-inflammatory and antiapoptotic effects against APAP-induced hepatotoxicity potentially through regulation of PI3K/Akt and NF-kβ signaling pathways.
