Focal adhesion proteins, vinculin and integrin β5, during early pregnancy in rat uterine epithelial cells: anastrozole favors their normal distribution

Int. j. morphol; 36 (1), 2018
SUMMARY: An alternative superovulator to replace clomiphene citrate is needed as clomiphene citrate is associated with low pregnancy rates. Anastrozole is an effective superovulator, but it has not been well researched. In order to determine the effectiveness of anastrozole as a superovulator and to comp...

The tankyrase inhibitor G007-LK inhibits small intestine LGR5+ stem cell proliferation without altering tissue morphology

Biol. Res; 51 (), 2018
Abstract Background The WNT pathway regulates intestinal stem cells and is frequently disrupted in intestinal adenomas. The pathway contains several potential biotargets for interference, including the poly-ADP ribosyltransferase enzymes tankyrase1 and 2. LGR5 is a known WNT pathway target gene and mark...

Minimal inhibitory concentration distributions and epidemiological cutoff values of five antifungal agents against Sporothrix brasiliensis

Mem. Inst. Oswaldo Cruz; 112 (5), 2017
BACKGROUND Sporothrix brasiliensis is the most virulent sporotrichosis agent. This species usually responds to antifungal drugs, but therapeutic failure can occur in some patients. Antifungal susceptibility tests have been performed on this species, but no clinical breakpoints (CBPs) are available. In th...

Protective effects of deferasirox and N-acetyl-L-cysteine on iron overload-injured bone marrow

Braz. j. med. biol. res; 50 (12), 2017
Using an iron overload mouse model, we explored the protective effect of deferasirox (DFX) and N-acetyl-L-cysteine (NAC) on injured bone marrow hematopoietic stem/progenitor cells (HSPC) induced by iron overload. Mice were intraperitoneally injected with 25 mg iron dextran every 3 days for 4 weeks to est...

BRD4 inhibition suppresses cell growth, migration and invasion of salivary adenoid cystic carcinoma

Biol. Res; 50 (), 2017
BACKGROUND: Bromodomain-containing protein 4 (BRD4) inhibition is a new therapeutic strategy for many malignancies. In this study, we aimed to explore the effect of BRD4 inhibition by JQ1 on in vitro cell growth, migration and invasion of salivary adenoid cystic carcinoma (SACC). METHODS: The human norma...

Effect of letrozole in carcinogen-plus-estrogen-induced endometrial hyperplasia in mice

Acta cir. bras; 31 (4), 2016
PURPOSE: To evaluate the effects of letrozole (Ltz) in carcinogen+estrogen-induced endometrial hyperplasia. METHODS: BALB/c female mice were divided into four groups of 12 animals each receiving an intrauterine dose of N-ethyl-N-nitrosourea (ENU) and weekly subcutaneous injections of estradiol hexaid...

Enterolobin induces rat paw oedema independently of PAF-acether

Mem. Inst. Oswaldo Cruz; 86 (supl.2), 1991
The potential participation of PAF-acether (PAF) on the paw oedema triggered by enterolobin was investigated. Intraplantar injections of enterolobin )5-20 µg/paw) yielded a dose response curve for edema which appeared after 30 min, peaked in the interval between 2-4 h and faded after 24h. The pre-treatm...
