Positive correlation between PEDF expression levels and macrophage density in the human prostate.

Background: In this study, we investigated the capacity of pigment epithelium-derived factor (PEDF) to modulate the recruitment and the differentiation of monocytes/macrophages both in vitro and in human prostate.

Methods: Using Boyden chambers, we assessed PEDF effect on the migration of monocytes and chemically activated RAW 264.7 macrophages.

Cutaneous phaeohyphomycosis caused by Paraconiothyrium cyclothyrioides.

Paraconiothyrium cyclothyrioides is a recently described coelomycetous fungal species. We present a case in a renal transplant patient with chronic skin lesions of the lower extremities caused by P. cyclothyrioides.

Green tea polyphenols and 1-α-OH-vitamin D₃ attenuate chronic inflammation-induced myocardial fibrosis in female rats.

Studies have suggested that 1-α-OH-vitamin D₃ and green tea polyphenols (GTPs) are promising dietary supplements for mitigating chronic inflammation-induced fibrosis of vessels because of their anti-inflammatory properties. This study evaluated (1) the impact of 1-α-OH-vitamin D₃ on myocardial fibrosis in female rats with chronic inflammation and (2) if 1-α-OH-vitamin D₃ and GTPs have an additive or synergistic effect to attenuate myocardial fibrosis in these female rats. A 3-month study of a 2 (no 1-α-OH-vitamin D₃ vs.

CRM1-dependent p53 nuclear accumulation in lung lesions of a bitransgenic mouse lung tumor model.

The p53 tumor suppressor gene plays an essential role in tumorigenesis, and the chromosomal region maintenance 1 (CRM1) has been suggested to export p53 protein from the nucleus to the cytoplasm. The objectives of the present study were to evaluate p53 expression and subcellular localization as well as CRM1 expression using immunohistochemistry in our established bitransgenic mouse lung tumor model. In this model, expression of the mutant human Ki-rasG12C allele was regulated in a doxycycline (DOX)-inducible, lung-specific manner.

Green tea polyphenols avert chronic inflammation-induced myocardial fibrosis of female rats.

Objective: Green tea proposes anti-inflammatory properties which may attenuate chronic inflammation-induced fibrosis of vessels. This study evaluated whether green tea polyphenols (GTP) can avert fibrosis or vascular disruption along with mechanisms in rats with chronic inflammation.

Treatments: Forty 3-month-old female rats were assigned to a 2 (placebo vs.

Protective actions of green tea polyphenols and alfacalcidol on bone microstructure in female rats with chronic inflammation.

This study investigated the effects of green tea polyphenols (GTP) and alfacalcidol on bone microstructure and strength along with possible mechanisms in rats with chronic inflammation. A 12-week study using a 2 (no GTP vs. 0.

Cytotoxic T cell immunity against the non-immunogenic, murine, hepatocellular carcinoma Hepa1-6 is directed towards the novel alternative form of macrophage colony stimulating factor.

Mouse Hepa1-6 hepatocellular carcinoma (HCC) cells were transduced with the membrane form of macrophage colony stimulating factor (mM-CSF). When mM-CSF transduced Hepa1-6 cells were injected subcutaneously into mice, these cells did not form tumors. The spleens of these immunized mice contained cytotoxic CD8+ T lymphocytes (CTL) that killed the unmodified Hepa1-6 cells.

Comprehensive mutational analysis and mRNA isoform quantification of TP63 in normal and neoplastic human prostate cells.

Background: The role of TP63 in cancer remains controversial since both oncogenic and tumor suppressive actions have been reported. p63 protein is found in the nuclei of basal cells of the normal prostate, yet it is absent in the vast majority of prostate cancer nuclei. Since a complex array of TP63 mRNA transcripts encode polypeptides with distinct functional properties, it is important to determine which forms are expressed in normal and prostate cancer tissue.
