Lapatinib-Loaded Nanocapsules Enhances Antitumoral Effect in Human Bladder Cancer Cell

In conclusion, NC-LAP demonstrate antitumoral effect in HER-positive bladder cells by inducing cell cycle arrest and apoptosis exhibiting better effects compared to the non-encapsulated lapatinib. Our work suggests that the LAP loaded in nanoformulations could be a promising approach to treat tumors that presents EGFR overexpression phenotype. Introduction Bladder cancer (BC) is a heterogeneous disease which presents several molecular characteristics associated with different clinical outcomes (1). Urothelial or transitional cell carcinoma (TCC) represent the most frequent type of bladder cancer (2) and are classified into two subtypes tumors depending on the formation pathway: non-muscle invasive bladder cancer (NMIBC) or muscle invasive bladder cancer (MIBC) (3). NMIBC are confined to the mucosa (stage Ta, CIS) or submucosa (stage T1) and are accounted for 60–80% of the diagnosed bladder cancer cases (4). The histological evaluation is the gold standard for the classification of the tumor allowing the implementation of the best possible therapeutic alternative. This strategy also allows the evaluation of the risks of recurrence and progression of the disease (5, 6). However, recent studies have focused on tumor classifications considering their molecular characteristics in order to diagnose tumor subtypes and establish the best possible therapeutic alternative (7, 8). Molecular analyzes have shown that approximately 75% of transitional cell carcinomas overexpre...

This study aimed to demonstrate how the organic acids and volatile profiles were impacted by coffee fermentation using four starter cultures (Meyerozyma caribbica (CCMA 0198), Saccharomyces cerevisiae (CCMA 0543), Candida parapsilosis (CCMA0544), and Torulaspora delbrueckii (CCMA 0684)) inoculated in two varieties of coffee (Bourbon Amarelo and Canário Amarelo) using natural and pulped natural processing methods and sensory perception. Real-time PCR (qPCR) was used to verify the dynamic behavior of yeast populations. Organic acids were detected using high performance liquid chromatography (HPLC) and gas chromatograp...

In this study, we loaded aldoxorubicin, an albumin-bound prodrug version of doxorubicin, onto NFP and tested the in vitro cytotoxicity in canine mammary carcinoma (CMT12, CMT25) and osteosarcoma (HMPOS, D-17, Abrams) cell lines. The half maximal inhibitory concentration (IC50) was determined with a luminescence-based cell viability assay. The IC50 for aldoxorubicin-loaded NFP was lower than free aldoxorubicin or doxorubicin in all cell lines, whereas non-drug loaded NFP had no cytotoxic effects. There were differences in IC50 between the osteosarcoma lines, with lower and higher IC50 for HMPOS and D-17 cells, respectively,...

CONCLUSIONS: Veterans eligible for VA servicers who are homeless, or at risk of becoming homeless, frequently sought care in the community for a variety of chronic health conditions. Health information exchanges and partner-based registries may represent an important tool for identifying vulnerable Veteran populations while reducing duplication of care.

In this study, we discovered that miR-561 expression was downregulated in human NSCLC tissues and cell lines. The overexpression of miR-561 inhibited NSCLC cell proliferation and cell cycle G1-S transition and induced apoptosis. The inhibition of miR-561 facilitated cell proliferation and G1-S transition and suppressed apoptosis. MiR-561 expression was inversely correlated with P-REX2a expression in NSCLC tissues. P-REX2a was confirmed to be a direct target of miR-561 by using a luciferase reporter assay. The overexpression of miR-561 decreased P-REX2a expression, and the suppression of miR-561 increased P-REX2a expression...
