Novotny, Bing Peng, Liangli Yu, Pei ChenAbstractBroccoli is a popular brassica vegetable and its consumption may decrease the occurrence of cancer in certain populations. To gain insight into the metabolites that may induce physiological responses to broccoli intake, a non-targeted metabolomic approach and a targeted approach for analysis of glucosinolate metabolites were developed using high resolution accurate mass spectrometry. A human study was conducted in which 6 subjects consumed a single meal of 200 g of uncooked broccoli florets. The metabolomic analysis revealed changes in endogenous metabolites and a decrease in hippuric acid after broccoli consumption. Targeted analysis using high-resolution, accurate mass-mass spectrometry (HRAM-MS) enabled detection of low concentrations (nM) of glucosinolate metabolites in human urine and plasma. Glucosinolate metabolites were found in human urine (13) and plasma (8), respectively. Metabolites from methoxyl-indole glucosinolates, arising from broccoli consumption, are reported for the first time. Most glucosinolate metabolites reached their peak concentration in urine 2-4 h after consumption while, in plasma, peak maxima were achieved 2 h after intake. The results suggest that glucoraphanin metabolites (sulforaphane, sulforaphane cysteine, sulforaphane N-acetyl cysteine) and indole metabolites (ascorbigen ...

ConclusionsTattooing of axillary LNs is safe and easily performed. Tattooing was helpful in identifying the marked LN in the majority of cases. This technique helps to ensure that metastatic LNs are identified and removed at surgery after NAT.

These enzymes which were initially found in Escherichia coli have attracted considerable attention as target molecules for cancer therapy. Nowadays, there are several topoisomerase inhibitors in the market to treat or at least control the progression of cancer. However, significant toxicity, low solubility and poor pharm...

ConclusionsOral HPV infection is significantly prevalent and widespread worldwide, particularly among men and among populations at risk. Prevalence has increased during the last two decades.
In conclusion, miR-142-3p overexpression may inhibit autophagy and promote the drug sensitivity of breast cancer cells to DOX by targeting HMGB1. The miR-142-3p/HMGB1 axis might be a novel target to regulate the drug resistance of breast cancer patients.Graphical abstractHigh-mobility group box 1 (HMGB1) is a direct functional target of miR-142-3p in breast cancer cells. MiR-142-3p overexpression may inhibit autophagy and promote the drug sensitivity of doxorubicin (DOX) by targeting HMGB1. The miR-142-3p/HMGB1 axis might be an important pathway regulating the sensitivity of breast cancer cells.
