recent evidences suggest that multiple myeloma phenotypes (mmps) are involved in the infiltration of multiple myeloma-affected marrow foci. in this study, the effects of arsenic trioxide on the invasive and angiogenic phenotypes of multiple myeloma (mm) cell line were assessed on a dose-response and time-course basis. multiple myeloma cell line, karpas 707, was treated with step-wise elevated c...

Arsenic is a ubiquitous trace element that has been shown to induce both systemic and carcinogenic effects. Epidemiological findings indicate that arsenic is a paradoxical human carcinogen that results in increased risk of skin, lung, bladder, liver and kidney cancers. Although the systemic and carcinogenic effects of arsenic have been widely studied in a variety of systems, the mechanisms of a...

Arsenic trioxide can inhibit proliferation and induce apoptosis in multiple myeloma (MM) cells in vitro and in vivo. In addition to affecting tumor growth, arsenic trioxide has been shown to inhibit angiogenesis, suggesting that it may have significant potency in the treatment of MM. Based on these observations, the clinical efficacy of arsenic trioxide was evaluated in patients with advanced r...

Inorganic trivalent arsenicals are vicinal thiol-reacting agents, and dithiothreitol (DTT) is a well-known dithiol agent. Interestingly, both decreasing and increasing effects of DTT on arsenic trioxide-induced apoptosis have been reported. We now provide data to show that, at high concentrations, DTT, dimercaptosuccinic acid (DMSA), and dimercaptopropanesulfonic acid (DMPS) decreased arsenic t...

Glioblastoma multiforme (GBM) is associated with high mortality due to infiltrative growth and recurrence. Median survival of the patients is less than 15 months, increasing requirements for new therapies. We found that both arsenic trioxide and 10058F4, an inhibitor of Myc, induced differentiation of cancer stem-like cells (CSC) of GBM and that arsenic trioxide drastically enhanced the anti-pr...

The Hedgehog (Hh) signaling pathway not only plays important roles in embryogenesis and adult tissue homeostasis, but also in tumorigenesis. Aberrant Hh pathway activation has been reported in a variety of malignant tumors including colon carcinoma. Here, we sought to investigate the regulation of the Hh pathway transcription factor Gli1 by arsenic trioxide and phosphoinositide 3-kinase (PI3K) ...

AIM To investigate the role of tumor apoptosis-inhibitory protein survivin in arsenic trioxide-induced apoptosis in VX-2 carcinoma in the rabbit liver by means of transcatheter arterial chemoembolization. METHODS Sixteen rabbits with 32 implanted hepatic VX-2 tumors were randomly divided into two groups. The experimental group received 2 mg of arsenic trioxide and 1 mL of ultra-fluid lipiodol...

Received: Revised: Accepted: May 29, 2013 September 15, 2013 September 18, 2013 The effects of resveratrol on arsenic trioxide-induced oxidative stress and arsenic efflux in spleen were determined in Wistar rats exposed to arsenic trioxide (As2O3). Wistar rats were segregated into four groups: control (0.9% normal saline), As2O3treated (2 mg/kg for 7 days, i.p.), resveratrol+As2O3-treated, resv...

Arsenic, arsenic trioxide and pentoxide, arsenous acids, arsenic acid and their salts (arsenites and arsenates) are carcinogenic substances (Carcinogen category 1) and do not, therefore, have MAK and BAT values (Greim 2002). The former TRK value (technical exposure limit) for arsenic and its inorganic compounds was 0.10 mg arsenic/m (measured as the inhalable fraction of the aerosol; calculated...
