Abstract
Peroxisome proliferator-activated receptor-gamma coactivator-1α (PGC-1α) transcriptional coactivators are key regulators of energy metabolism-related genes and are expressed in energy-demanding tissues. There are several PGC-1α variants with different biological functions in different tissues. The brain is one of the tissues where the role of PGC-1α isoforms remains less explored. Here, we used a toxin-based mouse model of Parkinson's disease (PD) and observed that the expression levels of variants PGC-1α2 and PGC-1α3 in the nigrostriatal pathway increases at the onset of dopaminergic cell degeneration. This increase occurs concomitant with an increase in glial fibrillary acidic protein levels. Since PGC-1α coactivators regulate cellular adaptive responses, we hypothesized that they could be involved in the modulation of astrogliosis induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Therefore, we analysed the transcriptome of astrocytes transduced with expression vectors encoding PGC-1α1 to 1α4 by massively parallel sequencing (RNA-seq) and identified the main cellular pathways controlled by these isoforms. Interestingly, in reactive astrocytes the inflammatory and antioxidant responses, adhesion, migration, and viability were altered by PGC-1α2 and PGC-1α3, showing that sustained expression of these isoforms induces astrocyte dysfunction and degeneration. This work highlights PGC-1α isoforms as modulators of astrocyte reactivity and as potential therapeutic targets for the treatment of PD and other neurodegenerative disorders.

Abstract
BACKGROUND Prostate cancer is one of the most common cancer types and it is the sixth leading cause of cancer-related death in men worldwide. Even though novel treatment modalities have been developed, it still a lifethreatening disease. Therefore novel compounds are needed to improve the overall survival. METHODS In our study, it was aimed to evaluate the anti-cancer activity of newly synthesized Platinum (II) [Pt(II)] complex on DU145, LNCaP and PC-3 prostate cancer cell lines. The cytotoxic activity of Pt(II) complex was tested by SRB and ATP cell viability assays. To detect the mode of cell death; fluorescent staining, flow cytometry and western blot analyses were performed. RESULTS The Pt(II) complex treatment resulted in a decrease in cell viability and increasing levels of apoptotic markers (pyknotic nuclei, annexin-V, caspase 3/7 activity) and a decrease in mitochondrial membrane potential in a dose dependent manner. Among cell types, tested PC-3 cells were found to be more sensitive to Pt(II) complex, demonstrating elevation of DNA damage in this cell line. In addition, Pt(II) complex induced Endoplasmic Reticulum (ER) stress by triggering ROS generation. More importantly, pre-treatment with NAC alleviated Pt(II) complex-mediated ER stress and cell death in PC-3. CONCLUSION These findings suggest an upstream role of ROS production in Pt(II) complex-induced ER stressmediated apoptotic cell death. Considering the ROS-mediated apoptosis inducing the effect of Pt(II) complex, it warrants further evaluation as a novel metal-containing anticancer drug candidate.

Abstract
Platinum-based anticancer drugs are one of the most widely used anticancer chemotherapeutics in oncology. Lonidamine (LND) could increase the response of human tumor cells to platinum(II) drugs in preclinical studies by working on the mitochondria. Herein, five platinum(IV) prodrugs conjugated with their potentiator LND are prepared, and most of the target complexes achieve improved anticancer activities compared with their platinum(II) precursors. Notably, Pt(NH3)2(LND)Cl3 (complex 1) derived from cisplatin achieve significantly improved anticancer activities against LNCaP cells and could trigger cancer cell death via an apoptotic pathway and the cell cycle arrest mainly at S phases. And the induction of apoptosis by complex 1 in LNCaP cells is closely associated with mitochondrial function disruption and reactive oxygen species (ROS) accumulation. Moreover, it is possessed of the ability to overcome cisplatin-resistance. Further research revealed that complex 1 could be easily reduced to release its platinum(II) precursor and axial ligand by ascorbic acid. All the results provid evidence to support the design strategy of conjugating platinum complexes with its potentiator to improve their anticancer effect.

Abstract
The recently developed iCELLigence™ real-time cell analyzer (RTCA) can be used for the label-free real-time monitoring of cancer cell proliferation, viability, invasion and cytotoxicity. The RTCA system uses 16-well microtiter plates with a gold microelectrode biosensor array that measures impedance when cells adhere to the microelectrodes causing an alternating current. By measuring the electric field generated in this process, the RTCA system can be used for the analysis of cell proliferation, viability, morphology and migration. The present review aimed to summarize the working method of the RTCA system, in addition to discussing the research performed using the system for various applications, including cancer drug discovery via measuring cytotoxicity.

Abstract
Pt(IV) complexes comprising a phenstatin analogue, as dual-targeting Pt(IV) prodrug, were designed and synthesized. They were found not only to carry the DNA binding platinum warhead into the tumor cells, but also to have a small molecular unit to inhibit tubulin polymerization. In vitro evaluation results revealed that Pt(IV) complexes showed better and more potent activity against the test human cancer cells including cisplatin resistant cell lines than their corresponding Pt(II) counterparts. In addition, the Pt(IV) derivative of cisplatin, complex 10, exhibited highly selective inhibition in human cancer cells and displayed no obvious toxicity to two human normal cell lines, respectively. Mechanism study suggested that complex 10 induced cell-cycle arrest at the G2/M phase and caused apoptotic cell death of human lung cancer NCI-H460 cells through the mitochondrial mediated pathway. Moreover, complex 10 effectively inhibited the tumor growth in the NCI-H460 xenograft model.

Enhanced cytotoxic activity of doxorubicin through the inhibition of autophagy in triple negative breast cancer cell line. Biochim Biophys Acta Gen Subj 2016; 1861:49-57.

Abstract
BACKGROUND The outcome of triple negative breast cancer is still poor and requires improvement with better therapy options. Autophagy has recently been shown to play a role in anticancer drug resistance. Therefore, we investigated if the effectiveness of doxorubicin was augmented by the inhibition of autophagy. METHODS MDA-MB-231 was used as a model cell line for triple negative breast cancer and 3-methyladenine was used as an inhibitor of autophagy. Cells were treated with 0.46-1.84μM doxorubicin and 2.5-10μM 3-methyladenine for 48h. Cell death mode was examined with M30 and M65 ELISA assays. ROS level and LDH activity was examined and the cellular acidic compartment of cells was monitored by acridine orange staining. The expression of various autophagy and apoptosis related proteins/genes were evaluated with Western blotting and RT-qPCR respectively. RESULTS Synergism was observed between the compounds (CI value<1.0). RT-qPCR analysis revealed that the combination resulted in a down-regulation of autophagy-related genes. Moreover, the combination resulted in a different cell death modality, upregulating necroptosis-related genes. This suggests that the mode of cell death may switch from apoptosis to necroptosis, which is a more severe form of cell death, when autophagy is inhibited. These results were further confirmed at protein level by Western blotting. CONCLUSION Inhibition of autophagy seems to sensitize triple negative breast cancer cells to doxorubicin, warranting further in vivo studies for the proof of this concept. GENERAL SIGNIFICANCE Autophagy has a key role in drug resistance in MDA-MB-231 cells. Therefore combinatorial approaches may effectively overcome resistance.
