Background: Invasive breast carcinoma of no special type (IBC-NST) is the most common type of breast cancer and mainly causes regional lymph-node metastasis (LNM). We investigated the potential for AKT2 expression as a predictive biomarker for LNM in IBC-NST. Methods: Forty-eight paraffin blocks containing IBC-NST primary tumors were divided into two groups based on presence or absence of LNM. Age, tumor grade, tumor size, lymphovascular invasion (LVI), and AKT expression were assessed. AKT2 expression was assessed based on immunohistochemical staining, while other data were collected from archives. Results: Multiple logistic regression results showed that AKT2 expression and LVI were significantly associated with LNM (odds ratio [OR], 5.32; 95% confidence interval [CI], 1.42 to 19.93 and OR, 4.46; 95% CI, 1.17 to 16.97, respectively). AKT2 expression was able to discriminate against LNM (area under the receiver operating characteristic, 0.799 ± 0.063; 95% CI, 0.676 to 0.921) at an H-score cutoff of 104.62 (83.3% sensitivity, 62.5% specificity). Conclusions: AKT2 expression has potential as a predictor of LNM in IBC-NST. The H-score cutoff for AKT2 expression can be used as a classification guide in future studies.
Ulcerative colitis (UC) is a part of incurable chronic inflammatory disease that has gained importance over the past few decades. A lot of research has been done to find effective treatments for UC, one of which is herbal medicine. Phaleria macrocarpa (PM), an Indonesian native plant, is thought to be an alternative therapy for UC because of its anti-inflammatory properties. Therefore, in this research, Phaleria macrocarpa Leaves Ethanol Extract (PMLEE) is used to assess its effect on UC by using Caspase-3 as apoptosis marker. PMLEE was made from dried material of PM that undergo maceration. Animals were separated into six groups: normal, negative control, positive control, and PMLEE groups (100, 200, 300 mg/kgBW). PMLEE was then injected to BALB/c mice that have been induced by dextran sodium sulphate (DSS) for 7 consecutive days. DSS is used to model UC in mice colon tissue. All animals were sacrificed and their colons were collected then stained with anti-Caspase-3. The stained sections were subsequently examined with ImageJ based on color intensity which generated H-Score as the results. Based on H-Score of each group, PMLEE 300mg has significantly upregulate the expression of Caspase-3 compare to the negative control (p=0.015). PMLEE also has a tendency to be dose dependent based on the significant difference between PMLEE doses. Therefore, it concludes that PMLEE is able to upregulate the expression of Caspase-3 in colon cells as in this study it was directly proportional.
Objective: Inflammatory disease occurs in the mucosal of the colon, or ulcerative colitis (UC) is one of subtypes of inflammatory bowel disease. The numerous of drug side effects for treatment of colitis give rise to use medicinal herbs as alternative therapies. Pomegranate peel extract has been used for the treatment of pain and inflammatory conditions. This study aimed to investigate the anti-inflammatory effects of pomegranate peel ethanol extract on mice colon through inflammation pathway which reduce inflammation score in mice model of chronic inflammation induced by dextran sodium sulfate (DSS).Methods: Thirty Swiss Webster mice divided randomly into 6 groups: Normal, aspirin 43 mg/kg/d (ASP), ellagic acid 26 mg/kg/d (ELG), DSS 2%b/v (DSS), pomegranate peel ethanol extract 240 mg/kg/d (DOSES-1), and 480 mg/kg/d (DOSES-2). All groups were given DSS 2% over 3 cycles except normal group (where each cycle in the DSS group consisted of 2% DSS in drinking water for 7 days, followed by a 7-day interval with normal drinking water). At the end of the experiment, colon samples were washed with water then buffered neutral formalin 10% fixed and paraffin embedded for histological analysis.Results: DOSES-1 and DOSES-2 were significantly reduced inflammation score in colon mice induced by DSS (p<0.05), mean score 2.01 and 2.02. Expression of cyclooxygenase (COX-2) was significantly decreased (p<0.05), mean score 27.48 and 17.77. Expression of iNOS was also significantly decreased (p<0.05), mean score 54.01 and 36.69. There were no significant differences between DOSES-1 and DOSES-2 groups with ASP and ELG group (p>0.05).
Conclusion:Pomegranate peel ethanol extract has an anti-inflammatory agent by reduces inflammation score, inhibiting COX-2 and iNOS expression on mice colon by DSS induced. Furthermore, pomegranate peel ethanol extract has equivalent effectiveness with aspirin and pure ellagic acid.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
