Among the patients who were initially or delayed in the axillary dissection, 37% had more than two lymph nodes. While in general, 16.7% of patients had a need for axillary lymph node dissection based on z11 criteria. Lymph-vascular invasion was a major contributor to lentil involvement in Sentinel and non-Sentinel nodes. CONCLUSION Frozen section pathology during the operation of sentinel lymph node biopsy has been initiated to prevent the need for a reoperation in early stage breast cancer patients. However, due to low tumor burden in patients who are candidates for this procedure, and the constraints in the initial sections and their false negative results, also the removal of frozen section will not have an effect on the rate of increasing reoperation and can be effective in reducing the time and cost of surgery.OBJECTIVE Chromosome detection is important in the diagnosis and prognosis of Myelodysplastic syndrome (MDS) patients. About 50% of MDS patients have chromosomal abnormalities. Moreover, chromosome 5 and 7 are common genetic abnormalities in MDS patients and use to identify prognosis risk group and the proper treatment in MDS patients. The objective of this study was to evaluate chromosomal abnormalities and clinical features of MDS patients in upper northern Thailand. METHODS Fifty bone marrow (BM) specimens were examined by conventional cytogenetic (CC) technique and fluorescence in situ hybridization (FISH) technique for detected chromosome 5 and 7 abnormalities. The clinical features were comparison between MDS patients with chromosomal abnormalities and those with normal karyotype. RESULTS Chromosomal abnormalities were detected in 8/50 MDS patients by CC and 17/50 cases by FISH technique. When the CC and FISH techniques were combined, chromosomal abnormalities increased to 21/50 cases.  Abnormalities of isolated chromosome 5 were found in 13 cases and were associated with lower level of percentage blast of BM (p = 0.003) and higher level of hemoglobin (p = 0.019). Moreover, abnormalities of chromosome 7 were found in 3 cases, 1 case of isolated del(7q) and 2 cases of -7 and del(7q) with complex abnormalities. These three cases were associated with higher level of percentage blast of BM (p = 0.010). CONCLUSION This study showed the frequency and pattern of chromosomal abnormalities of MDS patients in upper northern Thailand were different from other populations. MDS with isolated chromosome 5 abnormalities had clinical characteristics corresponding with patients in good prognosis risk group. However, MDS patients with chromosome 7 and complex abnormalities showed higher percentage blast of BM which high risk to progression to acute myeloid leukemia (AML). Combined CC and FISH techniques detect chromosomal abnormalities with greater frequency than when either technique is used alone..OBJECTIVE Hypoxia-associated biomarkers profiling may provide information for prognosis, staging, and subsequent therapy. We aim to evaluate whether the quantitative gene and protein expression of hypoxic response tumor markers - carbonic anhydrase IX (CAIX) and hypoxia- inducible factor 1 alpha (HIF1A) - may have a role in predicting survival in advanced breast cancer of Indonesian population.  https://www.selleckchem.com/products/NVP-AUY922.html  METHODS Tumor tissues and peripheral blood samples were collected from treatment - naïve locally advanced (LABC) or metastatic breast cancer patients (MBC) at Wahidin Sudirohusodo General Hospital (Makassar, South Sulawesi) and its referral network hospitals from July 2017 to March 2019. The level of mRNA (of blood and tumor tissue samples) and soluble protein (of blood samples) of CAIX and HIF1A were measured by RT-qPCR and ELISA methods, respectively, besides the standard histopathological grading and molecular subtype assessment. The CAIX and HIF1A expression, patients' age, tumor characteristics, surgery status, and neoadjuvant chemotherapy drug classes were further involved in survival analyses for overall survival (OS) and progression-free survival (PFS). RESULTS Forty (30 LABC, 10 MBC) eligible patients examined were 21 hormone-receptors positives (15 Luminal A, 6 Luminal B) and 19 hormone-receptors negatives (10 HER2-enriched, 9 triple-negative). The CAIX blood mRNA and CAIX soluble protein levels in hormone-receptors negative patients were higher than in hormone-receptor-positive patients (p .OBJECTIVE The study aimed to identify potential cell signaling pathways and protein targets of actions of atractylodin and β-eudesmol in cholangiocarcinoma, the two active compounds isolated from Atracylodes lancea using proteomics approach. METHOD The cholangiocarcinoma cell line, CL-6, was treated with each compound for 3 and 6 hours, and the proteins from both intra- and extracellular components were extracted. LC-MS/MS was applied following the separation of the extract proteins by SDS-PAGE and digestion with trypsin. Signaling pathways and protein expression were analyzed by MASCOT and STITCH software. RESULTS A total of 4,323 and 4,318 proteins were identified from intra- and extracellular components, respectively. Six and 4 intracellular proteins were linked with the signaling pathways (apoptosis, cell cycle control, and PI3K-AKT) of atractylodin and β-eudesmol, respectively. Four and 3 extracellular proteins were linked with the signaling pathways (NF-κB and PI3K-AKT) of atractylodin and β-eudesmol, respectively. CONCLUSION In conclusion, a total of 17 proteins associated with four cell signaling pathways that could be potential molecular targets of anticholangiocarcinoma action of atractylodin and β-eudesmol were identified through the application of proteomics approach.OBJECTIVE Nobiletin treatment on MDA-MB 231 cells reduces the expression of CXC chemokine receptor type 4 (CXCR4), which is highly expressed in cancer stem cell populations in tumor patients. However, the mechanisms of nobiletin in cancer stem cells (CSCs) remain elusive. This study was aimed to explore the potential target and mechanisms of nobiletin in cancer stem cells using bioinformatics approaches. METHODS Gene expression profiles by public COMPARE predicting the sensitivity of tumor cells to nobiletin. Functional annotations on gene lists are carried out with The Database for Annotation, Visualization and Integrated Discovery (DAVID) v6.8, and WEB-based GEne SeT Analysis Toolkit (WebGestalt). The protein-protein interaction (PPI) network was analyzed by STRING-DB and visualized by Cytoscape. RESULTS Microarray analyses reveal many genes involved in protein binding, transcriptional and translational activity. Pathway enrichment analysis revealed breast cancer regulation of estrogen signaling and Wnt/ß-catenin by nobiletin.
