In human glioma tumors, heme oxygenase-1 (HO-1) has been shown to be upregulated both when compared with normal brain tissues and also during oligodendroglioma progression. The cell types that express HO-1 have been shown to be mainly macrophages/microglia and T cells. However, many other reports also demonstrated that cell lines derived from glioma tumors(More)
The expression of heme oxygenase-1 (HO-1) was shown to be increased in multiple tumors compared with their surrounding healthy tissues and was also observed to be up-regulated in oral squamous cell carcinomas (OSCC). However, conflicting results were obtained and little information is available regarding HO-1 significance in head and neck squamous cell(More)
Vitamin D and its analogs have been shown to display anti-proliferative effects in a wide variety of cancer types including glioblastoma multiforme (GBM). These anticancer effects are mediated by its active metabolite, 1α, 25-dihydroxyvitamin D3 (calcitriol) acting mainly through vitamin D receptor (VDR) signaling. In addition to its involvement in(More)
There is evidence that p300, a transcriptional co-factor and a lysine acetyl-transferase, could play a role both as an oncoprotein and as a tumor suppressor, although little is known regarding its role in breast cancer (BC). First we investigated the role p300 has on BC by performing pharmacological inhibition of p300 acetyl-transferase function and(More)
The active metabolite of vitamin D, 1α, 25 dihydroxyvitamin D3 (calcitriol) is classically known to regulate calcium and phosphate homeostasis and bone mineralization. In addition, calcitriol has also been documented to act as a potent anticancer agent in multiple cell culture and animal models of cancer. However, major side effects, such as hypercalcemia,(More)
The active form of vitamin D3, calcitriol, plays a major role in maintaining calcium/phosphate homeostasis. In addition, it is a potent antiproliferative and prodifferentiating agent. However, when effective antitumor doses of calcitriol are employed, hypercalcemic effects are observed, thus precluding its therapeutic application. To overcome this problem,(More)
Here, we describe the design and synthesis of diethyl [(5Z,7E)-(1S,3R)-1,3-dihydroxy-9,10-secochola-5,7,10(19)-trien-23-in-24-yl] phosphonate (compound 10), which combines the low calcemic properties of phosphonates with the decreased metabolic inactivation due to the presence of a triple bond in C-24 and studied its in vitro effects on several cancer cell(More)
The active form of vitamin D3, 1α,25(OH)2D3, plays a major role in maintaining calcium/phosphate homeostasis. In addition, it is a potent antiproliferative and pro-differentiating agent. Unfortunately, it usually causes hypercalcemia in vivo when effective antitumour doses are used. It has therefore been found necessary to synthesise new analogues that(More)
