Abstract
BACKGROUND Cisplatin and platinum-based compounds have been used successfully to treat various cancers. However, their use is often restricted due to the acquired resistance by cancer cells. Over-expression of p53 and inhibition of NF-kB sensitize several cancer cells towards cisplatin-induced apoptosis. Quinacrine, a cytotoxic drug with predictable safety revealed to concurrently suppress NF-kB and activate p53, which may be an attractive adjuvant in cisplatin chemotherapy. Therefore, the objective of the present study was to establish the role of quinacrine as an adjuvant in lowering the dose of cisplatin during cancer therapy to circumvent its toxic effects. MATERIALS AND METHODS The colon cancer (HCT-8) cells were cultured and cell survival assays were performed using standard procedures. Cell cycle arrest and the extent of apoptosis were determined using a muse cell analyzer. Cancer survival proteins were analyzed using western blotting techniques. RESULTS AND CONCLUSION We demonstrated that concomitant use of quinacrine with cisplatin increased cell apoptosis, suppressed cell proliferation and inhibited colony formation in a colorectal cancer cell line. Moreover, cell cycle arrest in the G0/G1 and G2/M phases and upregulation of p53 expression were observed. There was also downregulation of NF-kB and Bcl-xL protein expressions, both of which are associated with enhanced cell apoptosis and an increase in the sensitivity of cancer cells to cisplatin, overcoming its chemoresistance. Overall, the results of the present study and available literature clearly indicate that the use of quinacrine as an adjuvant with cisplatin may enhance its anti-cancer activity and reduce chemoresistance.

Abstract
INTRODUCTION There is currently no consensus on the optimal chemotherapy regimen in the palliative first-line setting for East Asian patients with advanced esophageal squamous cell carcinoma (ESCC). AREAS COVERED We conducted a systematic review using a literature search of PubMed, Embase, and the Cochrane Library without date restrictions, and abstracts from major oncology congresses. Studies meeting the following criteria were included: East Asian patients ≥18 years old with pathologically proven metastatic or locally advanced unresectable ESCC; first-line chemotherapy; reporting of overall survival, progression-free survival, duration of response, overall response rate, and/or safety; randomized controlled trials, non-randomized controlled trials, and prospective or retrospective comparative studies. In total, 39 articles were identified for the following regimens: platinum plus fluoropyrimidine (n=9), platinum plus taxane (n=16), platinum plus fluoropyrimidine plus taxane (n=7), platinum plus fluoropyrimidine plus other (n=3), irinotecan plus platinum (n=2), taxane plus fluoropyrimidine (n=1). EXPERT OPINION The available data supports both taxane plus platinum regimens and fluoropyrimidine plus platinum regimens in the first-line treatment of East Asian patients with ESCC. Compared with data from doublet chemotherapy studies, triplet chemotherapy appeared to improve ORR, but did not seem to prolong OS, possibly due to an increased incidence of adverse events.

Abstract
It has been reported that paclitaxel activates cell cycle arrest and increases caspase protein expression to induce apoptosis in head and neck squamous cell carcinoma (HNSCC) cell lines. However, the potential signaling pathway regulating this apoptotic phenomenon remains unclear. The present study used OEC-M1 cells to investigate the underlying molecular mechanism of paclitaxel-induced apoptosis. Following treatment with paclitaxel, cell viability was assessed via the MTT assay. Necrosis, apoptosis, cell cycle and mitochondrial membrane potential (∆Ψm) were analyzed via flow cytometric analyses, respectively. Western blot analysis was performed to detect the expression levels of proteins associated with the MAPK and caspase signaling pathways. The results demonstrated that low-dose paclitaxel (50 nM) induced apoptosis but not necrosis in HNSCC cells. In addition, paclitaxel activated the c-Jun N-terminal kinase (JNK), but not extracellular signal-regulated kinase or p38 mitogen-activated protein kinase. The paclitaxel-activated JNK contributed to paclitaxel-induced apoptosis, activation of caspase-3, -6, -7, -8 and -9, and reduction of ∆Ψm. In addition, caspase-8 and -9 inhibitors, respectively, significantly decreased paclitaxel-induced apoptosis. Notably, Bid was truncated following treatment with paclitaxel. Taken together, the results of the present study suggest that paclitaxel-activated JNK is required for caspase activation and loss of ∆Ψm, which results in apoptosis of HNSCC cells. These results may provide mechanistic basis for designing more effective paclitaxel-combining regimens to treat HNSCC.

Abstract
This rapid report focuses on the pharmacodynamic mechanism of the carboplatin/paclitaxel combination and correlates it with its cytotoxicity. Consistent with the synergistic to additive antitumor activity (the combination index ranging from 0.53 to 0.94), cells exposed to this combination had significantly increased carboplatin-DNA adduct formation when compared to that of carboplatin alone (450 ± 30 versus 320 ± 120 adducts per 10(8) nucleotides at 2 h, p = 0.004). Removal of paclitaxel increased the repair of carboplatin-DNA adducts: 39.4 versus 33.1 adducts per 10(8) nucleotides per hour in carboplatin alone (p = 0.021). This rapid report provides the first pharmacodynamics data to support the use of carboplatin/paclitaxel combination in the clinic.

Abstract
Paclitaxel (PAC) and cisplatin (CIS) are two established chemotherapeutic drugs used in combination for the treatment of various solid tumors. However, the usage of PAC and CIS are limited because of the incidence of their moderate or severe neurotoxic side effects. In this study, we aimed to assess the protective role of salicylic acid (SA) against neurotoxicity caused by PAC and CIS. For this purpose, newborn Sprague Dawley rats were decapitated in sterile atmosphere and primary cortex neuron cultures were established. On the 10th day SA was added into culture plates. PAC and CIS were added on the 12th day. The cytotoxicity was determined by using the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay. Oxidative alterations were assessed using total antioxidant capacity and total oxidative stress assays in rat primary neuron cell cultures. It was shown that both concentrations of PAC and CIS treatments caused neurotoxicity. Although SA decreased the neurotoxicity by CIS and PAC, it was more effective against the toxicity caused by CIS rather than the toxicity caused by PAC. In conclusion it was clearly revealed that SA decreased the neurotoxic effect of CIS and PAC in vitro.

Abstract
The development of chemoresistance in patients represents a major challenge in cancer treatment. Lactate dehydrogenase-A (LDHA) is one of the principle isoforms of LDH that is expressed in breast tissue, controlling the conversion of pyruvate to lactate and also playing a significant role in the metabolism of glucose. The aim of this study was to identify whether LDHA was involved in oral cancer cell resistance to Taxol and whether the downregulation of LDHA, as a result of cisplatin treatment, may overcome Taxol resistance in human oral squamous cells. The OECM-1 oral epidermal carcinoma cell line was used, which has been widely used as a model of oral cancer in previous studies. The role of LDHA in Taxol and cisplatin resistance were investigated and the synergistic cytotoxicity of cisplatin and/or Taxol in oral squamous cells was analyzed. Cell viability was analyzed by MTT assay, LDHA expression was analyzed by western blot analysis and siRNA tranfection was performed to knock down LDHA expression. The present study results showed that decreased levels of LDHA were responsible for the resistance of oral cancer cells to cisplatin (CDDP). CDDP treatments downregulated LDHA expression, and lower levels of LDHA were detected in the CDDP-resistant oral cancer cells compared with the CDDP-sensitive cells. By contrast, the Taxol-resistant cancer cells showed elevated LDHA expression levels. In addition, small interfering RNA-knockdown of LDHA sensitized the cells to Taxol, but desensitized them to CDDP treatment, while exogenous expression of LDHA sensitized the cells to CDDP, but desensitized them to Taxol. The present study also revealed the synergistic cytotoxicity of CDDP and Taxol for killing oral cancer cells through the inhibition of LDHA. This study highlights LDHA as a novel therapeutic target for overcoming Taxol resistance in oral cancer patients using the combined treatments of Taxol and CDDP.

Abstract
Chemoresistance is a major cause of mortality of patients with advanced and metastatic hepatocellular carcinoma (HCC), the fifth most common cancer in the world. We employed a molecular approach to inhibit cell proliferation and induce apoptosis in HepG2 cells, originated from human hepatocarcinoma. TRADD gene expression was knocked down by an antisense oligonucleotide (ASO TRADD), resulting in TRADD protein decrease by 60%, coinciding with increase of apoptotic cell death of up to 30%. Combination of the ASO TRADD with the cytotoxic drugs 5-fluorouracil or paclitaxel did not improve chemosensitivity of HepG2 cells, while the combined administration of the ASO TRADD with proteasome inhibitors MG132 or ALLN inhibited cell proliferation by 80% and 93%, respectively. Taken together, these findings reveal the importance to combine proteasome inhibitors with silencing of anti-apoptotic signalling components to target HCC cells effectively and provide useful data for developing potential treatments of HCC.

Abstract
A novel methoxy poly(ethylene glycol)-b-poly(l-glutamic acid)-b-poly(l-phenylalanine) (mPEG-b-P(Glu)-b-P(Phe)) triblock copolymer was prepared and explored as a micelle carrier for the co-delivery of paclitaxel (PTX) and cisplatin (cis-diamminedichlo-platinum, CDDP). PTX and CDDP were loaded inside the hydrophobic P(Phe) inner core and chelated to the middle P(Glu) shell, respectively, while mPEG provided the outer corona for prolonged circulation. An in vitro release profile of the PTX+CDDP-loaded micelles showed that the CDDP chelation cross-link prevented an initial burst release of PTX. The PTX+CDDP-loaded micelles exhibited a high synergism effect in the inhibition of A549 human lung cancer cell line proliferation over 72 h incubation. For the in vivo treatment of xenograft human lung tumor, the PTX+CDDP-loaded micelles displayed an obvious tumor inhibiting effect with a 83.1% tumor suppression rate (TSR%), which was significantly higher than that of a free drug combination or micelles with a single drug. In addition, more importantly, the enhanced anti-tumor efficacy of the PTX+CDDP-loaded micelles came with reduced side-effects. No obvious body weight loss occurred during the treatment of A549 tumor-bearing mice with the PTX+CDDP-loaded micelles. Thus, the polypeptide-based combination of PTX and CDDP may provide useful guidance for effective and safe cancer chemotherapy.

Abstract
Background Over-expression of Aurora kinases promotes the tumorigenesis of cells. The aim of this study was to determine the preclinical profile of a novel pan-Aurora kinase inhibitor, BPR1K653, as a candidate for anti-cancer therapy. Since expression of the drug efflux pump, MDR1, reduces the effectiveness of various chemotherapeutic compounds in human cancers, this study also aimed to determine whether the potency of BPR1K653 could be affected by the expression of MDR1 in cancer cells. Principal Findings BPR1K653 specifically inhibited the activity of Aurora-A and Aurora-B kinase at low nano-molar concentrations in vitro. Anti-proliferative activity of BPR1K653 was evaluated in various human cancer cell lines. Results of the clonogenic assay showed that BPR1K653 was potent in targeting a variety of cancer cell lines regardless of the tissue origin, p53 status, or expression of MDR1. At the cellular level, BPR1K653 induced endo-replication and subsequent apoptosis in both MDR1-negative and MDR1-positive cancer cells. Importantly, it showed potent activity against the growth of xenograft tumors of the human cervical carcinoma KB and KB-derived MDR1-positive KB-VIN10 cells in nude mice. Finally, BPR1K653 also exhibited favorable pharmacokinetic properties in rats. Conclusions and Significance BPR1K653 is a novel potent anti-cancer compound, and its potency is not affected by the expression of the multiple drug resistant protein, MDR1, in cancer cells. Therefore, BPR1K653 is a promising anti-cancer compound that has potential for the management of various malignancies, particularly for patients with MDR1-related drug resistance after prolonged chemotherapeutic treatments.

Abstract
BACKGROUND Matrix metalloproteinase-3 (MMP-3) is expressed in various carcinomas; however, its function is not clearly established. This study was to assess its possible role in oral squamous cell carcinomas (OSCCs). MATERIALS AND METHODS Specimens of seven oral pre-malignant lesions (OPMLs) and 92 OSCCs were subjected to MMP-3 detection by RT-PCR and Western blot. Antisense oligodeoxynucleotides (AODNs) of MMP-3 were used to transfect OSCC (OECM-1 and SCC-9) and esophageal carcinoma (CE81T/VGH) cell lines, and their growth was subsequently analyzed by XTT and soft-agar colony assay. RESULTS MMP-3 transcript was preferentially expressed in OSCCs (71 of 92, 77%) than in OPMLs (two of seven, 29%; P = 0.012). Both MMP-3 transcript and protein levels were significantly higher in OSCC masses than in neighboring tissues (P < 0.0001 and P = 0.04, respectively). Growth of the three cell lines was not affected, while the colony numbers of OECM-1 and CE81T/VGH were significantly reduced by the transfection of MMP-3 AODNs (P = 0.002 and P = 0.004, respectively). SCC-9 did not form colonies in soft-agar/medium. CONCLUSIONS MMP-3 function may be required in most OSCCs, and it may support the anchorage-independent growth of both OSCC and esophageal carcinoma.

Abstract
Encouraging results have recently been reported in patients (pts) with locally advanced unresectable squamous cell carcinoma of the head and neck (SCCHN) when induction chemotherapy (IC) is used and followed by radiotherapy (RT). The present study assessed the therapeutic response of an aggressive regimen consisting of docetaxel (TXT), cisplatin (CDDP) and 5-fluorouracil (5-Fu) as IC and concurrent with RT in pts with locally advanced (stages III and IV) SCCHN. 42 pts (35 male and 7 female) with a mean age of 58 years suffering from stages III and IV (Mo) SCCHN were included to this organ preservation phase II clinical trial. The site of the primary tumors was the anterior mouth in 9 pts, base of tongue and oropharynx in 12, middle third of the face in 8 and larynx in 13. The performance status of the pts was 0-1 according to WHO and above 80% according to Karnofsky classification. IC consisted of TXT (40 mg/m2), CDDP (40 mg/m2) and 5-Fu (350 mg/m2) every two weeks (wks) for a total of four courses and repeated, coupled with RT (66-68 cGys total dose fractionated at 200 Gy per day, 5 days a week), for up to seven wks. In total, pts received eight courses of chemotherapy (CT) at the end of RT treatment. Pts were evaluated at the end of IC, after RT and every six wks thereafter. 41 pts were eligible for evaluation after IC (one died from myocardial infarction) and 39 after completion of treatment (two died during RT). Statistical multivariate analysis was performed using SPSS (11) package. Complications from IC and RT were evaluated according to WHO criteria and included mucositis Grade (Gr) IV in 10% of the pts, Gr III in 50%, Gr II in 20%. Anemia presented in 40% of the pts with Gr II, 40% with Gr I, neutropenia 17% with Gr IV, 20% with Gr III, 30% with Gr II, thrombocytopenia 3% with Gr III, 10% with Gr I and xerostomia up to Gr II in 70% of the pts. The response rate (RR) after IC was complete response (CR) for 10 pts (24.4%), partial response (PR) for 22 (53.7%) and no response (NR) for 9 (21.9%). At the end of the treatment the RR in the intention-to-treat population were CR for 25 pts (64.1%), and PR for 14 (35.9%). Follow up ranges from 18 to 56 months (mts). 14 pts died during follow-up time. The mean survival time is 41 mts and the median 40. 2 pts with CR developed local recurrence and two distant metastases, whereas all pts with PR developed progressive disease (PD) and all but two are dead from disease. It is evident from this phase II study that TXT-CDDP-5Fu based IC followed by the same regimen coupled with RT improves local control. Pts that showed CR after IC continued to maintain disease status during RT (P-value=0.0181). In pts with SD concurrent RT did not alter dramatically disease outcome. Patients who showed complete response after both IC and RT presented a four-year survival rate of 74% compared to a 30% to partial responders (P-value=0.0001). Results are encouraging and further study of the toxicity and follow-up is needed to validate treatment effectiveness.

Abstract
The newly identified MMP-28 has been shown to be expressed in several types of carcinomas, however, its functional role in transformation events is unknown. This study was to assess whether this proteinase plays a role in oral tumor malignancy. By using RT-PCR, we found that expression of MMP-28 was significantly higher in 92 oral squamous cell carcinomas (OSCCs) (52/92, 56.5%) than in seven oral premalignant lesions (OPMLs) (0/7, 0%) (P=0.004). No statistically significant correlation was found between MMP-28 expression and tumor stage, thickness, size, and metastasis. Both mRNA and protein of MMP-28 were preferentially concentrated in OSCC specimens than in neighboring tissues as analyzed by semi-quantitative RT-PCR (P=0.015) and immunohistochemistry, respectively. Transfection of OSCC and esophageal carcinoma cell lines with MMP-28 antisense oligodeoxynucleotide (AODN) resulted in the reduced secretion of MMP-28 protein and the ability of colony formation in soft agar without affecting cell growth. Our findings show the close correlation between MMP-28 and OSCC, and support a role for MMP-28 in the anchorage-independent growth of both OSCC and esophageal carcinomas.

Abstract
BACKGROUND Paclitaxel (Taxol), is known to induce mitotic arrest and apoptosis by inhibiting the depolymerisation of microtubules. Tumour growth and metastasis are affected by the metabolic rate and angiogenesis. We investigated the effect of Paclitaxel on tumour metabolism and markers of angiogenesis, vascular endothelial growth factor (VEGF). MATERIALS AND METHODS Tissue samples of 39 patients diagnosed with invasive carcinoma were obtained. The solid tumours were cultured with Paclitaxel at a concentration of 4.27 ug/ml for 24 h. The metabolic rate of the samples was measured by ATP Bioluminescence assay and the levels of VEGF in culture medium were measured by ELISA. RESULT The mean ATP concentration of control and test groups were 7.169 and 5.004 rlu/ml, respectively, suggesting that the metabolic rate was inhibited by Paclitaxel. The mean VEGF levels in the control and test groups were 5.335 and 4.567 pg/ml, respectively. All data analysed were statistically significant (P < 0.005). The finding of the study showed that Paclitaxel could inhibit metabolic rate in solid tumour. It could also downregulate VEGF. CONCLUSION Our result suggested that Paclitaxel is an effective cytotoxic possibly with anti-angiogenic effects.
