The mechanism for inactivation of the KIP family cyclin-dependent kinase inhibitor (CDKI) genes, the p21, p27, and p57 genes, in gastric cancer cells was tested by treating the cells with either the DNA demethylation agent, 5-aza-2'-deoxycytidine or the histone deacetylase inhibitor, n-butyric acid
Breast cancer is one of the most commonly diagnosed malignancies in women. Despite the remarkable success of mammography screening and use of adjuvant systemic therapy, it is estimated that approximately 200,000 new diagnoses will be made this year and 40,000 deaths will occur due to this disease
The interest of butyric salts is based on their capacity to promote differentiation of malignant cells and inhibition of tumor development. The phenotypic modifications are rapidly reversible and require the continuous presence of butyric salts in the target area, which raises problems for
Histone deacetylases (HDACs) are often overexpressed in cancer cells, leading to altered expression and activity of numerous proteins involved in carcinogenesis. Recent evidence suggests that expression of class I HDACs is increased in ovarian carcinomas and plays a significant role in
Several cellular mechanisms contribute to the neuroendocrine differentiation of prostate cancer cells, including exposure to sodium butyrate (NaBu), a naturally occurring salt of the short chain fatty acid n-butyric acid. NaBu belongs to a class of histone deacetylase inhibitors with potential
Both (But)2cAMP and n-butyric acid suppressed the proliferation of TM-1 cells and induced the formation and elongation of the cellular processes in vitro. Prednisolone stimulated the proliferation of TM-1 cells and increased the number of polygonal cells in vitro. These results indicated that
n-Butyric acid and its "polymorphic" derivatives have been largely but somehow "blindly" studied in oncology and in red cell diseases with consistent results through decades indicating a strong maturative effect determined by enhancement of gene transcription. Although these effects have been
Neurologic abnormalities are among the most serious extraintestinal complications of infection with Shiga toxin (Stx)-producing bacteria. Histopathologic examination of tissues from patients with extraintestinal sequelae suggested that Stxs damage endothelial cells. It is shown here that human brain
Basement membranes are frequently absent in small-cell lung cancer (SCLC). To study this phenomenon, the production of laminin by SCLC cells, both in vitro and in vivo, has been investigated and compared with the laminin production by lung carcinomas of other histotypes (non-SCLC, NSCLC).
A link between high-fat diet consumption and obesity-related diseases is the disruption of the gut bacterial population, which promotes local and systemic inflammation. Wheat germ (WG) is rich in bioactive components with antioxidant and anti-inflammatory This is a study of the interaction of 23 kinds of amino acids, peptides and their analogues with Os((II)) at different pD values. Experiments show that in acidic conditions, the carboxyl group in amino acids can coordinate with Os((II)), and there exists H-D coupling of the dihydrogen of the probe
This study compares the antitumor activity of five mono- and polyesters of n-butyric acid derived from monosaccharides in the murine model of Crocker 180 TG Sarcoma. Tumor incidence at ten days, mean survival time and final survival rate were significantly affected in all cases. Combined treatment
The use of n-butyric acid has been associated with induction of cell differentiation and bypassing of genetic defects in the suppression of malignancy. This biological response modifier satisfies the requirements for specificity and low toxicity, and its use can be considered as an alternative
