Combination chemotherapy forms the backbone of cancer treatment. There is a need for new drug combinations for the treatment of mantle cell lymphoma (MCL). Herein, we show that gallium maltolate, a novel gallium compound, synergizes with bortezomib, a proteasome inhibitor, to induce cell death in MCL Granta cells. Cells exposed to either agent displayed caspase-3 activation, a loss of mitochond...

In the present study, the agonists and antagonists of DP receptor were used to examine whether the PGD2-DP signaling pathway affects neuronal function. Primary cultured hippocampal neuron was prepared and treated with aluminum maltolate (100 μM) to establish the neuronal damage model. PGD2 and cAMP content was detected by ELISA. L-PGDS and DPs mRNA and protein expression were measured by RT-PCR...

The in situ detection of cells undergoing apoptosis is increasingly important in the analysis of injury and degeneration in the central nervous system. Limited information is presently available on the quantification of apoptosis in paraffin-embedded brain tissue sections, a technique which would be most useful in the evaluation of archival tissue for diagnostic and experimental purposes. In th...

A mouse model of cystitis caused by uropathogenic Escherichia coli was used to study the distribution of gallium in bladder tissue following oral administration of gallium maltolate during urinary tract infection. The median concentration of gallium in homogenized bladder tissue from infected mice was 1.93 μg/g after daily administration of gallium maltolate for 5 days. Synchrotron X-ray fluore...

BACKGROUND Hepatocellular carcinoma (HCC) is a particularly lethal cancer with few treatment options. Since gallium is known to accumulate specifically in HCC tumors but not in non-tumor liver, we investigated two gallium compounds, gallium nitrate (GaN) and gallium maltolate (GaM), as potential new agents for treating HCC. MATERIALS AND METHODS The anti-proliferative and apoptotic activities...

OBJECTIVE To explore the effects of exposure to aluminum (Al) on long-term potentiation (LTP) and AMPA receptor subunits in rats in vivo. METHODS Different dosages of aluminum-maltolate complex [Al(mal)3] were given to rats via acute intracerebroventricular (i.c.v.) injection and subchronic intraperitoneal (i.p.) injection. Following Al exposure, the hippocampal LTP were recorded by field pot...

Introduction: Due to the cell labeling potentials of various metal-maltol complexes, the idea of developing a possible cell labeling imaging agent using single photon emission computed chromatography (SPECT) with [In]-maltolate complex has been investigated. Methods: [In] labeled 3-hydroxy-2-methyl-4H-pyran-4-onate ([In]-maltolate) was prepared using freshly prepared [In]InCl3 and 3-hydroxy-2-m...
