Objective: Hepatic cancer is known as primary liver cancer and hepatocellular carcinoma (HCC). Newly silver nanoparticles gained importance due to its advantages and multiple potential such as molecular imaging agent, antimicrobial, wound healing, anti-inflammatory and anticancer activity. The current study deals to assess therapeutic property silver nanoparticles (AgNPs) against diethylnitrosamine (DENA), and carbon tetrachloride (CCL4) induced hepatic cancer. Methods: Thirty male albino rats (200-250g) were distributed into four groups and hepatic cancer was induced with a single intraperitoneal dose of 200 mg/kg body weight of DENA. Two weeks later, animals received subcutaneous injections of CCl4 once a week in a dose of 3 ml/kg body weight for 6weeks. Serum biomarkers, antioxidants enzymes, inflammatory markers were evaluated to find the anti-proliferative potential of silver nanoparticles. Histological evaluation and microscopic reports were also done to document the results of the current work. Results: AgNPs significantly recover the serum marker enzymes of hepatic parameter AST, ALT, ALP, and total bilirubin and also decreased the levels of NO, IL-6 and TNF-α. Histopathological features also exhibited recovery of a hepatic architecture in cancer-induced rats. Moreover, the immunohistochemical investigation demonstrated that the levels of PCNA, and Caspase-3, which are hepatocarcinogenic markers, were significantly improved by AgNPs. Conclusion: These results concluded that AgNPs showed promising curing effects on hepatocellular ailments.

Abstract Background Garcinia lanceifolia Roxb. has been used by many ethnic communities of Northeast India to mitigate various disorders like dyspepsia, ulcers, diabetes, etc. However, a robust scientific study on its antidiabetic and antiulcer potential is unavailable till date. The aim of this present study is to scientifically validate if the antidiabetic and antiulcer effects reported by the ethnic tribes of Assam has any scientific value or not. The effects were tested in adult Wistar albino rats using approved animal models for preclinical testing of pharmacological activities. Results The hydroalcoholic extract of the bark of Garcinia lanceifolia Roxb. was prepared and its LD50 was calculated. The LD50 was determined to be greater than 5000 mg/kg body weight. The extract at doses of 250 mg/kg body weight and 500 mg/kg body weight was found to exhibit a very potent dose-dependent antidiabetic activity. The results were backed by a battery of test including analysis of serum levels of blood glucose, lipid profiles, in vivo antioxidant enzymes, and histopathological studies. Evidence of dose-dependent antiulcer activity of the extract was backed by robust scientific data. It was found that HAEGL induced a significant dose-dependent increase in the ulcer index in both alcohol-induced and acetic acid-induced ulcer models, which was evident from the macroscopic observation of the inner lining of the gastric mucosa and the histological evaluation of the extracted stomach. Conclusion The results suggested that the bark of Garcinia lanceifolia (Roxb.) has significant antidiabetic and antiulcer potential. Further studies with respect to the development herbal dosage forms and its safety evaluation are required.

This study evaluated the effect of aqueous extract of Senna occindentalis leaves on some biochemical parameters in Wistar rats. Twenty albino rats equally divided into four experimental groups were used. One group served as control and received the carrier solvent treatment. Three test groups were treated with S. occidentalis extract at 500, 1000 and 1500 mg/kg body weight respectively. The experiment lasted for 14 days after which the rats were sacrificed and blood collected for biochemical and haematological evaluation. Liver-body weight ratio was computed and liver histoarchitecture was investigated. The results showed that all haematological parameters were significantly (P<0.05) affected except the mean corpuscular haemoglobin concentration and mean corpuscular volume. There were also significant (P<0.05) alterations in the activities of gamma-glutamyl transferase, alanine aminotransferase, and aspartate aminotransferase, as well as the levels of total protein, albumin and globulin in the serum. No significant (P>0.05) alterations were observed in the computed liver-body weight ratio but marked alterations in histoarchitecture of the liver cells were present. These alterations in the haematological parameters, liver function enzymes and histological evaluation suggest a selective toxicity of the extract on the animals.

The assessment of silver nanoparticles biosynthesized and characterized using UV-Spec, FTIR, XRD, TGA, SEM, TEM from marine red seaweed Halymenia porphyroides have been evaluated for its anti-hyperglycemic activity in vivo. The anti-diabetic efficacy of the biosynthesized silver nanoparticles from marine red seaweed Halymenia porphyroides was studied by chemically inducing diabetes in the experimental Wistar albino rats through Alloxan monohydrate, which ultimately results in hyperglycemia at a dosage of 50 mg/kg body weight given orally for about 28 days. The outcome of the results was estimated by various biochemical parameters from the treatment group with silver nanoparticle (50 mg/Kg i.p) biosynthesized from Halymenia porphyroides. The anti-diabetic efficacy of the treatment group showed a decrease in the levels of blood glucose levels, total cholesterol, triglycerides, low-density lipoprotein, and phospholipids whereas the body weight and HDL increase was observed. The histopathological evaluation of the pancreas of the treated group of animals revealed the restoration and regeneration of β-cells of the pancreas with moderate swelling as compared to that of the chemically induced alloxan diabetic group of animals.

Abstract Background: Hepatocellular carcinoma plays an inadequate mention in the second cause of death because of cancer worldwide. An alternative therapy with high rate of prognosis and also without side effects. Several data indicated the therapeutic efficacy of Enhalus acoroides. There were no scientific studies on chemopreventive and antioxidant potential of Enhalus acoroides against hepatocellular carcinoma.Purpose: To investigate the hepatoprotective efficacy of ethanolic extract of Enhalus acoroides (EEEA) against DEN induced hepatocellular carcinoma using wistar albino rats.Study design: Animals were divided into five groups each comprising six rats. Normal saline given to Group I- Control rats. By using DEN, liver cancer was induced to Group II, III, IV and V rats as single intraperitoneally injection (100 mg/kg body weight). At the beginning of 6th week, Groups III rats received EEEA (200mg/kg body weight/day) upto 16 weeks. Group IV rats received EEEA for one week before the administration of DEN and continued till the 16th week. After the administration of DEN, Group V positive control rats received Silymarin (100 mg/kg body weight) at the beginning of 6th week and continued upto 16 weeks. The efficacy of Enhalus acoroides for its Hepatoprotective and antioxidant properties during its simultaneous treatment against DEN induced liver damage was evaluated in rats. Methods: The hepatoprotective efficacy of EEEA (200 mg/kg) was investigated against DEN (100 mg/kg/b.w) induced hepatotoxicity, was measured by evaluating serum liver markers levels (ALT, AST, GGT and ALP), Kidney markers (Urea and Creatinine), Lipid profile (TG, HDL, LDL & Total cholesterol) and Serum tumor markers (DNA, RNA, AFP and CEA). EEEA-aided antioxidant defence against hepatotoxic insult of DEN was measured by evaluating various Antioxidant biomarkers (GSH, SOD, CAT, GPx, Vit C and Vit E) Morphometric gross analysis and Histopathological studies were done to support the outcomes of the present study.Results: A significant increased antioxidant defence and reduced MDA levels in the serum of EEEA treated animals compared to the DEN induced animals. The resulting data showed that the administration of EEEA decreased the serum liver markers levels, kidney markers, Lipid profile and serum tumor markers when compared to the untreated rats. The histopathological anomalies were altered on administration of EEEA indicating its protective effects on hepatocytes when compared with untreated rats.Conclusions: Our consequences established that crude ethanolic extract of Enhalus acoroides shown an effective impact against DEN-induced hepatocellular carcinoma, and serves as a better option for chemopreventive treatments.

Aims: We aimed to find common and distinct molecular characteristics between LIHC and CHOL based on miRNA-TF-gene FFL. Background: Liver hepatocellular carcinoma (LIHC) and cholangiocarcinoma (CHOL) are two main histological subtypes of primary liver cancer with a unified molecular landscape, and feed-forward loops (FFLs) have been shown to be relevant in these complex diseases. Objective: To date, there has been no comparative analysis of the pathogenesis of LIHC and CHOL based on regulatory relationships. Therefore, we investigated the common and distinct regulatory properties of LIHC and CHOL in terms of gene regulatory networks. Method: Based on identified FFLs and an analysis of pathway enrichment, we constructed pathway-specific co-expression networks and further predicted biomarkers for these cancers by network clustering. Resul: We identified 20 and 36 candidate genes for LIHC and CHOL, respectively. The literature from PubMed supports the reliability of our results. Conclusion: Our results indicated that the hsa01522-Endocrine resistance pathway was associated with both LIHC and CHOL. Additionally, six genes (SPARC, CTHRC1, COL4A1, EDIL3, LAMA4 and OLFML2B) were predicted to be highly associated with both cancers, of which SPARC was significantly highly ranked. Other: In addition, we inferred that the Collagen gene family, which appeared more frequently in our overall prediction results, might be closely related to cancer development.

AbstractLiver cancer is the fourth leading cause of cancer-related death. Hepatocellular carcinoma (HCC) is a primary liver cancer that results from chronic hepatitis caused by multiple predisposing factors such as viral infection, alcohol consumption, and non-alcoholic fatty liver disease. Accumulating studies have indicated that dysfunction of the gut epithelial barrier and hepatic translocation of gut microbes may be implicated in the pathogenesis of HCC. However, the translocated bacteria in HCC patients remains unclear. Here, we characterised tumour-associated microbiota in patients with liver cancer and focused on HCC. We observed that the number of amplicon sequence variants in tumour-associated microbiota was significantly higher compared with that in non-tumour regions of the liver. The tumour-associated microbiota consisted of Bacteroidetes, Firmicutes, and Proteobacteria as the dominant phyla. We identified an unclassified genus that belonged to the Bacteroides, Romboutsia, uncultured bacterium of Lachnospiraceae as a signature taxon for primary liver cancer. Additionally, we identified Ruminococcus gnavus as a signature taxon for HCC patients infected with hepatitis B and/or hepatitis C viruses. This study suggests that tumour microbiota may contribute to the pathology of HCC.
