Abstract
Colorectal cancer (CRC) is the third most common malignant disease worldwide, and its incidence is increasing, but the molecular mechanisms of this disease are highly heterogeneous and still far from being fully understood. Increasing evidence suggests that fibrosis mediated by abnormal activation of fibroblasts based in the microenvironment is associated with a poor prognosis. However, the function and pathogenic mechanisms of fibroblasts in CRC remain unclear. Here, combining scrna-seq and clinical specimen data, DAZ Interacting Protein 1 (DZIP1) was found to be expressed on fibroblasts and cancer cells and positively correlated with stromal deposition. Importantly, pseudotime-series analysis showed that DZIP1 levels were up-regulated in malignant transformation of fibroblasts and experimentally confirmed that DZIP1 modulates activation of fibroblasts and promotes epithelial-mesenchymal transition (EMT) in tumor cells. Further studies showed that DZIP1 expressed by tumor cells also has a driving effect on EMT and contributes to the recruitment of more fibroblasts. A similar phenomenon was observed in xenografted nude mice. And it was confirmed in xenograft mice that downregulation of DZIP1 expression significantly delayed tumor formation and reduced tumor size in CRC cells. Taken together, our findings suggested that DZIP1 was a regulator of the CRC mesenchymal phenotype. The revelation of targeting DZIP1 provides a new avenue for CRC therapy.

Abstract
Background The Proteasome (PSM) is a large multi-catalytic protease complex consisting of a 20S core particle and a 19S regulatory particle whose main function is to accept and degrade ubiquitinated substrates, are now considered as one of the potential regulators of tumor proliferation, and stemness maintenance. However, to date, studies on the relationship between PSM and hepatocellular carcinoma (HCC) are limited. Methods This study used a bioinformatics approach combining validation experiments to investigate the biological mechanisms that may be related with PSM. A series of experiments in vivo and in vitro were performed to explore the function of the 26S proteasome non-ATPase regulatory subunit 13 (PSMD13) in HCC. Results HCC patients can be divided into two clusters. Cluster 1 (C1) patients having a significantly worse prognosis than Cluster (C2). Two subtypes had significant differences in proliferation-related signaling. In particular, the frequency of TP53 mutation was significantly higher in C1 than in C2. In addition, PSM-associated genes were highly consistent with the expression of DNA repair-related signatures, suggesting a potential link between PSM and genomic instability. We also found that downregulation of PSMD13 expression significantly inhibited stemness of tumor cells and impaired the Epithelial mesenchymal transition (EMT) process. Finally, the correlation between the PSMD13 and Ki67 was found to be strong. Conclusion PSM is a valid predictor of prognosis and therapeutic response in patients with HCC disease. Furthermore, PSMD13 may be a potential therapeutic target.

Abstract
Ubiquitination and deubiquitination are important post-translational regulatory mechanisms responsible for fine tuning the antiviral signaling. In this study, we identified a deubiquitinase, the ubiquitin-specific peptidase 7/herpes virus associated ubiquitin-specific protease (USP7/HAUSP) as an important negative modulator of virus-induced signaling. Overexpression of USP7 suppressed Sendai virus and polyinosinic-polycytidylic acid and poly(deoxyadenylic-deoxythymidylic)-induced ISRE and IFN-β activation, and enhanced virus replication. Knockdown or knockout of endogenous USP7 expression had the opposite effect. Coimmunoprecipitation assays showed that USP7 physically interacted with tripartite motif (TRIM)27. This interaction was enhanced after SeV infection. In addition, TNF receptor-associated factor family member-associated NF-kappa-B-binding kinase (TBK)-1 was pulled down in the TRIM27-USP7 complex. Overexpression of USP7 promoted the ubiquitination and degradation of TBK1 through promoting the stability of TRIM27. Knockout of endogenous USP7 led to enhanced TRIM27 degradation and reduced TBK1 ubiquitination and degradation, resulting in enhanced type I IFN signaling. Our findings suggest that USP7 acts as a negative regulator in antiviral signaling by stabilizing TRIM27 and promoting the degradation of TBK1.-Cai, J., Chen, H.-Y., Peng, S.-J., Meng, J.-L., Wang, Y., Zhou, Y., Qian, X.-P., Sun, X.-Y., Pang, X.-W., Zhang, Y., Zhang, J.

Abstract
There are two commonly accepted methods for detecting microsatellite status. One is to detect amplified microsatellite loci by polymerase chain reaction (PCR) and the other is to detect mismatch repair gene (MMR) protein expression by immunohistochemistry (IHC). PCR detection is considered to be accurate in clinical operations while IHC is widely used due to ease of operation and lesser expense. In order to compare IHC with PCR in detecting microsatellite status in colorectal carcinoma, a total of 569 samples of colorectal carcinoma resection were collected in the Department of Pathology, Nanjing Drum Tower Hospital, between June 2014 and June 2017. In all samples, IHC and PCR was used to detect microsatellite status and the consistency of results between the two methods was compared. We found that 48 cases of microsatellite instability (MSI) were detected by PCR including 37 cases of microsatellite instability high (MSI-H), 11 cases of microsatellite instability low (MSI-L), and 521 cases of MSS. MSI accounted for 8.44% of all cases and MSI-H accounted for 6.50%. IHC results of the 569 patients showed that 69 cases were deficient mismatch repair (dMMR) and 500 cases were proficient mismatch repair (pMMR). dMMR accounted for 12.13% of all cases. Loss expression of PMS2 protein was the most common while MSH6 was rare. The coincidence rate of the two methods for detecting microsatellite states was 91.92%. IHC and the PCR method had high consistency in microsatellite status. Compared with PCR, the IHC method is more economical and more convenient for clinical operations. When the 4 repair proteins were without deficiency detected by IHC, it could be diagnosed as MSS/MSI-L and further PCR was not necessary. When any repair protein was found to be deficient, PCR detection was needed to determine whether MSI existed. Our conclusion will save a lot of time and costs in clinical work.

Abstract
AIM To assess the efficacy and safety of a new treatment modality, cellular immune therapy based on personalized peptide vaccination (PPV-DC-CTL) combined with radiotherapy, for treating advanced hepatocellular carcinoma (HCC).
METHODS A total of nine patients with advanced HCC were enrolled. Multidisciplinary consultation confirmed that all the patients definitely had no opportunity of surgery, because four patients had multiple liver metastases (the number of liver lesions > 3), one patient had liver metastases and portal vein tumor thrombosis, one patient had lung and bone metastases, two patients had liver and lung metastases and one patient had liver metastasis and peritoneal metastasis. Patients with metastasis were treated with precise radiotherapy combined with PPV-DC-CTL.
RESULTS Following radiotherapy and one to three cycles of PPV-DC-CTL treatment, AFP levels were significantly decreased in six patients and imaging assessment of the lesions showed a partial response (PR) in three patients and stable disease in the other three patients. The response rate was 33% and disease control rate was 66%. This regimen was found to be safe and well tolerated. None of the patients developed liver or kidney side effects. Only one patient developed grade II bone marrow suppression and the remaining patients had no significant hematological side effects.
CONCLUSION Radiotherapy combined with PPV-DC-CTL provides a new therapeutic strategy for patients with advanced HCC, which is well tolerated, safe, feasible and effective.

Abstract
Colorectal cancers (CRCs) exhibiting microsatellite instability (MSI) have special biological behavior. The clinical predictors for MSI and its survival relevance for the Chinese population were still unclear. Seven hundred ninety-five CRC patients were retrospectively assessed. Mismatch repair (MMR) proteins (MSH2, MSH6, PMS1, and MLH1) expression was detected by immunohistochemistry using tumor tissues of all patients. DNA MSI status was analyzed by polymerase chain reaction in 182 samples randomly selected from the 795 cases. Among all CRC tumor tissues, 97 cases (12.2%) were with an MMR protein-deficient (MMR-D) phenotype, whereas 698 cases (87.8%) were with an MMR proteins intact (MMR-I) phenotype. A total of 21 (11.5%) CRCs were identified as having high microsatellite instability, 156 (85.7%) tumors were having microsatellite stability (MSS), and five (2.7%) were having low microsatellite instability. Importantly, MMR status was demonstrated to be moderately consistent with MSI status (κ=0.845, 95% confidence interval [CI] 0.721, 0.969). Unconditional logistic regression analysis revealed age, number of lymph node, tumor diameter, and tumor site as predictors for MSI with a substantial ability to discriminate different MSI status by area under curve of 80.62% using receiver operation curve. Compared with MMR-I, MMR-D was an independent prognostic factor for longer overall survival (hazard ratio =0.340, 95% CI 0.126, 0.919; P=0.034). MMR-D is an independent prognostic factor for better outcome. Our results may provide evidence for individualized diagnosis and treatment of CRC, but this will require further validation in larger sample studies.

Abstract
Kristen rat sarcoma viral oncogene homolog (KRAS) and microsatellite instability (MSI) are prognostic markers of colorectal cancer (CRC). However, the clinical value is still not fully understood, when giving the consideration to both the molecular makers. Five hundred fifty-one patients with CRC were retrospectively assessed by determining their clinicopathological features. KRAS mutations were detected by polymerase chain reaction. MSI, a defect in the mismatch repair (MMR) system, was detected by immunohistochemistry. The prognostic value of KRAS in combination with MSI was studied. Among 551 CRC patients, mutations in KRAS codon 12 and KRAS codon 13 were detected in 34.5% and 10.5% of patients, respectively. Four hundred one tumors were randomly selected to detect for MMR proteins expression. In this analysis, 30 (7.5%) tumors that had at least 1 MMR protein loss were defined as MMR protein-deficient (MMR-D), and the remaining tumors were classed as MMR protein-intact (MMR-I). According to KRAS mutation and MSI status, CRC was classified into 4 groups: Group 1, KRAS-mutated and MMR-I; Group 2, KRAS-mutated and MMR-D; Group 3, KRAS wild and MMR-I; and Group 4, KRAS wild and MMR-D. We found that patients in Group4 had the best prognosis. In conclusion, combination status of KRAS and MSI status may be used as a prognostic biomarker for CRC patient, if validated by larger studies.

Abstract
Objective: BRCA1 (breast cancer susceptibility gene 1) and RAP80 (receptor-associated protein 80) play key roles in predicting chemosensitivity of platinum and taxanes. A randomized trial was carried out to compare non-selected cisplatin-based chemotherapy with therapy customized according to BRCA1 and RAP80 expression. Methods: Advanced stage NSCLC patients whose tumor specimen was sufficient for molecular analysis were randomized (1∶3) to the control or experimental arm. Patients in the control arm received docetaxel/cisplatin; in the experimental arm, patients with low RAP80 expression received gemcitabine/cisplatin (Arm 1), those with intermediate/high RAP80 expression and low/intermediate BRCA1expression received docetaxel/cisplatin (Arm 2), and those with intermediate/high RAP80 expression and high BRCA1 expression received docetaxel alone (Arm 3). The primary end point was progression-free survival (PFS). Results: 226 patients were screened and 124 were randomized in this trial. ORR in the four subgroups was 22.6%, 48.4%, 30.3% and 19.2%, respectively (P=0.08); PFS was 4.74, 5.59, 3.78 and 2.73 months, respectively (P=0.55); and OS was 10.82, 14.44, 10.86 and 10.86 months, respectively (P=0.84). The common adverse effects included neutropenia, nausea, anemia and fatigue. Conclusions: No statistically significant difference of ORR, PFS or OS is observed in the experimental arms compared with the control arm. Patients with low RAP80 mRNA levels have a trend of better survival and higher response rate to gemcitabine/cisplatin chemotherapy.

Abstract
Gallbladder carcinoma (GBC) is a rare and highly aggressive disease. The diagnosis of this cancer is difficult due to its occult onset. Hence, GBC is often detected late and at an advanced stage. Although physicians and researchers are continually working to improve the treatment for advanced-stage disease, GBC is usually associated with short survival times. The present study describes a case of GBC that was first diagnosed with accompanying cholecystolithiasis at the time of cholecystectomy. Cancer relapse occurred 1.5 years after the cholecystectomy. Multidisciplinary collaboration was involved in the decision-making process for the treatment of this aggressive recurrence, and the survival time was successfully extended to 26 months. Importantly, high-grade intraepithelial neoplasia and positive margins had previously been detected post-cholecystectomy at a different institution, but were ignored. Relapse may have been preventable had the cancer been diagnosed when it was initially observed. Taken together, these findings suggest that multidisciplinary collaboration should be considered for the management of advanced GBC, whereby patients will benefit from improved survival times. Furthermore, it is recommended that samples obtained from patients undergoing cholecystectomy should more carefully analyzed for evidence of cancerous or precancerous tissues.

Abstract
Mouse platelet basic protein (CXCL7/mPBP) was cloned from thymic stromal cells and further identification indicated that it was expressed in thymic monocytes/macrophages (Mo/Mphis). Recombinant mPBP was chemoattractive for target cells of polymorphonuclear leucocytes, peritoneal Mo/Mphis and splenic lymphocytes with distinct potencies. CXCR2 was identified to be a cognate receptor for mPBP. Mouse thymocyte subsets of CD4-CD8- double-negative (DN), CD4+CD8+ double-positive (DP), CD4+CD8- single-positive (CD4SP) and CD4-CD8+ single-positive (CD8SP) expressed cell surface CXCR2 with different positive percentages and expression levels. mPBP was chemoattractive for thymocyte subsets with the potency order DN>DP> CD8SP>CD4SP, consistent with the levels of CXCR2 expressed on the respective cells. Thus, mPBP in thymus is functionally redundant with chemokine CXCL12/ SDF-1. Moreover, our finding that thymic Mo/Mphis can produce mPBP implies that they may have other functions apart from acting as scavengers in thymus.

Abstract
The impact of maintenance therapy on progression-free survival and overall survival as well as quality of life of Chinese patients with metastatic colorectal cancer has long been under discussion. Recently, some phase III clinical trials have revealed that maintenance therapy can significantly prolong the progression-free survival while maintain an acceptable safety profile. Based on this evidence and common treatment practice in China, we now generated one Expert Consensus on Maintenance Treatment for Metastatic Colorectal Cancer in China to further specify the necessity of maintenance therapy, suitable candidates for such treatment, and appropriate regimens.

Abstract
Aberrant methylation of the transcription factor AP-2 epsilon (TFAP2E) has been attributed to 5-fluorouridine (5-FU) sensitivity. 5-Aza-2'-deoxycytidine (DAC), an epigenetic drug that inhibits DNA methylation, is able to cause reactive expression of TFAP2E by demethylating activity. This property might be useful in enhancing the sensitivity of cancer cells to 5-FU. However, the effect of DAC is transient because of its instability. Here, we report the use of intelligent gelatinases-stimuli nanoparticles (NPs) to coencapsulate and deliver DAC and 5-FU to gastric cancer (GC) cells. The results showed that NPs encapsulating DAC, 5-FU, or both could be effectively internalized by GC cells. Furthermore, we found that the NPs enhanced the stability of DAC, resulting in improved re-expression of TFAP2E. Thus, the incorporation of DAC into NPs significantly enhanced the sensitivity of GC cells to 5-FU by inhibiting cell growth rate and inducing cell apoptosis. In conclusion, the results of this study clearly demonstrated that the gelatinases-stimuli NPs are an efficient means to simultaneously deliver epigenetic and chemotherapeutic drugs that may effectively inhibit cancer cell proliferation.

Abstract
Radiotherapy is the main locoregional control modality for many types of unresectable tumors, including gastric cancer. However, many patients fail radiotherapy due to intrinsic radioresistance of cancer cells, which has been found to be strongly associated with cancer stem cell (CSC)-like properties. In this study, we developed a nanoparticle formulation to deliver miR-200c, which is reported to inhibit CSC-like properties, and then evaluated its potential activity as a radiosensitizer. miR-200c nanoparticles significantly augmented radiosensitivity in three gastric cancer cell lines (sensitization enhancement ratio 1.13–1.25), but only slightly in GES-1 cells (1.06). In addition to radioenhancement, miR-200c nanoparticles reduced the expression of CD44, a putative CSC marker, and the percentage of CD44+ BGC823 cells. Meanwhile, other CSC-like properties, including invasiveness and resistance to apoptosis, could be suppressed by miR-200c nanoparticles. CSC-associated radioresistance mechanisms, involving reactive oxygen species levels and DNA repair capacity, were also attenuated. We have demonstrated that miR-200c nanoparticles are an effective radiosensitizer in gastric cancer cells and induce little radiosensitization in normal cells, which suggests that they are as a promising candidate for further preclinical and clinical evaluation.

Abstract
PURPOSE Previous studies confirmed that genotyping uridine diphosphate glucuronosyltransferase (UGT) 1A1*28 polymorphisms could predict the side effects in cancer patients using irinotecan (IRI) and then reduce IRI-induced toxicity by preventative treatment or decrease in dose. However, the association between UGT1A1*6 polymorphisms and IRI-induced severe toxicity in Asian patients is still unclear. The aim of this study was to evaluate the association between UGT1A1*6 polymorphisms and IRI-induced severe neutropenia as well as diarrhea in Asian patients. METHODS We searched all papers on PubMed and Embase from February 1998 to August 2013. Then we assessed the methodologies quality, extracted data and made statistics analysis using STATA software. To uncover the sources of heterogeneity, subgroup meta-analysis was conducted according to the dosage of IRI. RESULTS Eleven papers were included according to the inclusion and exclusion criteria after searching Pubmed and Embase. Overall, an increased risk of severe toxicity in Asian patients with UGT1A1*6 polymorphisms was found. Patients with heterozygous variant of UGT1A1*6 showed an increased risk [odds ratio (OR) = 1.98, 95 % confidence intervals (CI) 1.45-2.71, P < 0.001], and homozygous mutation showed an even higher risk (OR = 4.44, 95 % CI 2.42-8.14, P < 0.001) for severe neutropenia. For severe diarrhea, heterozygous variant of UGT1A1*6 showed no significant risk, while the homozygous variant performed a notable risk (OR = 3.51, 95 % CI 1.41-8.73, P = 0.007). Subgroup meta-analysis indicated that for patients harboring either heterozygous or homozygous variant, low dose of IRI also presented comparably increased risk in suffering severe neutropenia. CONCLUSION In this meta-analysis, UGT1A1*6 polymorphisms were revealed as potential biomarkers, predicting IRI-induced severe toxicity in patients from Asia, and increased incidences of severe neutropenia could occur in both high/medium and low doses of IRI.

Abstract
Malignant renal subcapsular effusions commonly arise from primary or metastatic renal neoplasms. The current case report presents a rare case of malignancy with a massive renal subcapsular effusion accompanied by a malignant pleural effusion of an unknown primary site, which underwent progression to carcinomatous meningitis during chemotherapy. The type of adenocarcinoma present was determined by effusion cytology. Intravenous chemotherapy (docetaxel plus oxaliplatin and gemcitabine plus cisplatin) were administered; however, the disease still progressed. Time to progression was 9 months during treatment of gefitinib. Comprehensive therapies, including intracavity chemotherapy, immunotherapy and gefitinib, were shown to be effective and prolonged the patient's survival time.

Abstract
Cancer stem cells (CSCs) are recently discovered as vital obstacles for the successful cancer therapy. Emerging evidences suggest that miR-200c functions as an effective CSCs inhibitor and can restore sensitivity to microtubule-targeting drugs. In the present work, the intelligent gelatinases-stimuli nanoparticles (NPs) was set up to co-deliver miR-200c and docetaxel (DOC) to verify their synergetic effects on inhibition of CSCs and non-CSC cancer cells. After tumor cells were treated with miR-200c NPs, miR-200c and its targeted gene class III beta-tubulin (TUBB3)TUBB3 expression were evaluated. The effects of miR-200c/DOC NPs on tumor cell viability, migration and invasion as well as the expression of E-cadherin and CD44 were studied. The antitumor effects of miR-200c/DOC NPs were compared with DOC NPs in xenograft gastric cancer mice. Moreover, the residual tumors after treatment were subcutaneously seeded into nude mice to further investigate the effective maintenance of NPs. We found that the gelatinases-stimuli NPs facilitated miR-200c into cells, achieving sustained miR-200c expression in tumor cells during 9 days. The miR-200c/DOC NPs significantly enhanced cytotoxicity of DOC, possibly by decreasing TUBB3 level, and reversing EMT. The miR-200c NPs achieved high levels of in vivo accumulation and long retention in gastric cancer xenografts after intravenous administration. The miR-200c/DOC NPs prominently suppressed in vivo tumor growth with elevated miR-200c and E-cadherin levels and down-regulated TUBB3 and CD44 expressions. When the residual tumors after miR-200c/DOC NPs treatment were re-transplanted into nude mice, the tumors demonstrated the slowest growth speed. The miR-200c/DOC NPs may provide a promising modality for co-delivery of nucleic acid and drugs to simultaneously inhibit CSCs and non-CSC cancer cells.

Abstract
Although the role of E proteins in the thymocyte development is well documented, much less is known about their function in peripheral T cells. Here we demonstrated that CD4 promoter-driven transgenic expression of Id1, a naturally occurring dominant-negative inhibitor of E proteins, can substitute for the co-stimulatory signal delivered by CD28 to facilitate the proliferation and survival of naïve CD4+ cells upon anti-CD3 stimulation. We next discovered that IL-2 production and NF-κB activity after anti-CD3 stimulation were significantly elevated in Id1-expressing cells, which may be, at least in part, responsible for the augmentation of their proliferation and survival. Taken together, results from this study suggest an important role of E and Id proteins in peripheral T cell activation. The ability of Id proteins to by-pass co-stimulatory signals to enable T cell activation has significant implications in regulating T cell immunity.

Abstract
Nanoscale drug carriers have been extensively developed to improve drug therapeutic efficiency. However, delivery of chemotherapeutic agents to tumor tissues and cells has not been favorably managed. In this study, we developed a novel “intelligent” nanoparticle, consisting of a gelatinase-cleavage peptide with poly(ethylene glycol) (PEG) and poly(ɛ-caprolactone) (PCL)-based structure for tumor-targeted docetaxel delivery (DOC-TNPs). The docetaxel-loaded PEG-PCL nanoparticles (DOC-NPs) that did not display gelatinase-stimuli behaviors were used as a control. We found clear evidence that the DOC-TNPs were transformed by gelatinases, allowing drug release and enhancing the cellular uptake of DOC (P < 0.01). In vivo biodistribution study demonstrated that targeted DOC-TNPs could accumulate and remain in the tumor regions, whereas non-targeted DOC-NPs rapidly eliminated from the tumor tissues. DOC-TNPs exhibited higher tumor growth suppression than commercialized Taxotere® (docetaxel; Jiangsu Hengrui Medicine Company, Jiangsu, China) and DOC-NPs on hepatic H22 tumor model via intravenous administration (P < 0.01). Both in vitro and in vivo experiments suggest that the gelatinase-mediated nanoscale delivery system is promising for improvement of antitumor efficacy in various overexpressed gelatinase cancers.

Abstract
Circulating tumor cells (CTC) have been identified in peripheral blood from cancer patients especially those with metastatic lesions. Recently, the analysis of CTC has been developed rapidly and showed good prospects for individualized chemotherapy. The field of CTC research is very important since gene-expression profiling becomes feasible and real time when using CTC as the sample of evaluation. This review was to summarize present CTC detection, enrichment, or both methods and their contribution to individualized chemotherapy.

Abstract
Inappropriate gene silencing and subsequent promiscuous activity define the transformation of many solid tumours including renal cell carcinoma (RCC). Here, we report that UNC5C, one of the Netrin-1 receptors, was frequently inactivated in RCC cell lines and primary tumours. UNC5C protein was expressed in the proximal convoluted tubules of the human kidney, the presumed origin of clear cell RCC (ccRCC) and papillary RCC (pRCC). Compared to paired adjacent non-malignant tissues, both UNC5C mRNA and protein expression were significantly down-regulated in RCC. Immunohistochemical analysis showed that UNC5C was inactivated in 94.3% of the samples and the loss of UNC5C occurred at the early stage of RCC. Methylation specific PCR showed that UNC5C promoter was methylated in two renal carcinoma cell lines. Pharmacologic demethylation alone or in combination with inhibition of deacetylation dramatically induced UNC5C expression. Furthermore, bisulfite genomic sequencing (BGS) confirmed that dense methylation existed in UNC5C promoter. In paired tumour samples, UNC5C methylation was observed in 12 out of 44 patients (27.3%). Moreover, we analysed the loss of heterozygosity (LOH) of UNC5C in renal cell carcinoma, the LOH was observed in 27 out of 44 patients (61.4%). Finally, restoration of UNC5C expression suppressed the colony formation of renal carcinoma cells. In addition, UNC5C inhibited tumour cell proliferation, migration and enhanced chemosensitivity to cisplatin and etoposide. Therefore, UNC5C acts as a tumour suppressor in RCC and is down-regulated in RCC. Loss of heterozygosity and DNA methylation contribute to the inactivation of UNC5C in renal cell carcinoma.

Abstract
New approaches targeting molecular abnormalities specific to primary hepatocellular carcinoma (PHC) has offered a new method to improve patient outcome. The increasing knowledge in the molecular pathogenesis of PHC as well as the introduction of molecular targeted therapies in oncology has created an encouraging trend in the management of this malignancy. Early studies of targeted therapies for hepatocellular carcinoma, including targeting the EGFR pathway and inhibiting angiogenesis and multikinase inhibitors, have shown effective and great perspective. This review summarizes the basic knowledge of those key aspects of the molecular pathogenesis. Relevant preclinical and clinical information on novel compounds for PHC are also reviewed.

Abstract
The genetic polymorphism of TP53 codon 72 is thought to have significant effect on lung cancer risk, but the results are inconsistent. In this meta-analysis, we assessed 23 published studies involving 15,857 subjects of the association between TP53 codon 72 polymorphism and risk of lung cancer. For the homozygote Pro/Pro and Pro allele carriers (Pro/Pro+Pro/Arg), the ORs for all studies combined (7495 cases and 8362 controls) were 1.221 (95% CI=1.046-1.425; P=0.021 for heterogeneity) and 1.148 (95% CI=1.040-1.266; P=0.008 for heterogeneity). In the stratified analysis by ethnicity, significantly increased risks were found in Asians (3254 cases and 3350 controls) for both the homozygote Pro/Pro (OR=1.395; 95% CI=1.206-1.613; P=0.806 for heterogeneity) and the Pro allele carriers (OR=1.109; 95% CI=1.000-1.228; P=0.458 for heterogeneity). In Caucasians (3359 cases and 3953 controls), significantly elevated risk was associated with Pro allele carriers (OR=1.180; 95% CI=1.029-1.353; P=0.073 for heterogeneity). In the subgroup analyses by pathological type, the ORs for the homozygote Pro/Pro and Pro allele carriers were 1.289 (95% CI=1.027-1.618; P=0.096 for heterogeneity) and 1.168 (95% CI=1.062-1.284; P=0.231 for heterogeneity) for lung adenocarcinoma (2724 cases and 6591 controls). When stratified by smoking status, the pooled OR was 1.440 (95% CI=1.078-1.923; P=0.042 for heterogeneity) for the Pro allele carriers among smokers (1480 cases and 1414 controls). Although some statistical bias could not be eliminated, this meta-analysis suggests that the Pro allele is a low-penetrant risk factor for developing lung cancer. Additionally, we found that this phenomenon was more prominent in subgroups such as in Asians and Caucasians, in lung adenocarcinoma, or in smokers.

Abstract
OBJECTIVE To observe the influence of different frequencies of acupuncture on the therapeutic effect in patients with cerebral infarction at convalescence. METHODS Ninety-seven cases were randomly divided into an observation group I (n = 50) and an observation group II (n = 47). They were treated with same Chinese drugs and western medicine and electroacupuncture at Jiquan (HT 1), Quchi (LI 11), Hegu (LI 4), Huantiao (GB 30), etc. The observation group I was treated twice each day and the observation group II once each day. After treatment of 30 days, their therapeutic effects were observed. RESULTS The total effective rate of 94.0% for improvement of limb activity in the observation group I was better than 78.7% in the observation group II (P < 0.05); the therapeutic effects for choking when taking water, dysphagia, vague mind and slurred speech were similar in the two groups (P > 0.05). CONCLUSION The therapeutic effect of acupuncture twice each day on cerebral infarction at convalescence is superior to that of once daily.

Abstract
Rhizoma Paridis total saponin (RPTS) had been identified as the major components responsible for the anti-tumor effects of the herb Rhizoma Paridis, which had been used in China for centuries to treat many diseases including tumor. To elucidate the anti-tumor mechanism of RPTS, a proteomic analysis was carried out with RPTS treatment in HepG2 cells. More than 50 proteins showed a significant change between control (0.01% DMSO) and RPTS (IC(50) approximately 10microg/ml) treated cells after 48h. Twelve proteins had been identified by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) using peptide fingerprinting from 15 protein spots (density difference >2 fold between the control and RPTS-treated group). Among them, six proteins were down-regulated (dUTPase, hnRNP K, GMP synthase, etc.) and six proteins were up-regulated (DNase gamma, Nucleoside diphosphate kinase A, Centrin-2, etc.) by RPTS treatment in HepG2 cells as determined by spot volume (p<0.05). Most of the identified proteins were associated with tumor initiation, promotion, and progression. These findings might offer valuable insights into the mechanism of anti-tumor effect affected by RPTS treatment in HepG2 cells.

Abstract
BACKGROUND & OBJECTIVES Angiogenesis plays an important role in tumorigenesis and metastasis. This study was to investigate the inhibitory effect and mechanism of tetrandrine on angiogenesis in vitro and in vivo. METHODS MTT assay was used to observe the effect of tetrandrine on the proliferation of human umbilical vein endothelial cells (HUVECs) and human colorectal carcinoma LoVo cells. Transwell migration assay and tube formation assay were used to observe the impact of tetrandrine on cell migration and tube forming ability of HUVECs. LoVo cells were transplanted into nude mice. Microvessel density (MVD) was measured in nude mouse xenografts after intragastric administration of tetrandrine. RESULTS Tetrandrine (2-8 microg/mL) inhibited the proliferation of HUVECs (24.6%-76.9%) and LoVo cells (11.6%-14.0%) after 48 h treatment. When HUVECs were incubated with 2-8 microg/mL tetrandrine, the number of tubules was reduced and the lumen lost its integrity after 24 h; the number of migrating HUVECs was decreased after 12 h as compared with the control group (P < 0.001). Furthermore, MVD was much less in LoVo cell xenografts treated with 80mg/kg tetrandrine than in those treated with normal saline (P = 0.035). CONCLUSIONS Tetrandrine effectively suppresses angiogenesis in vitro, which may be through inhibiting cell proliferation, migration and tube-formation, inducing apoptosis and suppressing DNA synthesis of HUVECs. Tetrandrine also has an antiangiogenic effect on LoVo cell xenografts in nude mice.

Abstract
Our previous studies have defined a differentiation program followed by the newly generated single-positive (SP) thymocytes before their emigration to the periphery. In the present study, we further characterize the development of CD4SP cells in the thymic medulla using mainly intrathymic adoptive transfer assays. By analyzing the differentiation kinetics of the donor cells, which were shown to home correctly to the medullary region following adoptive transfer, we established the precursor-progeny relationship among the four subsets of CD4SP thymocytes (SP1-SP4) and demonstrated that the progression from SP1 to SP4 was unidirectional and largely synchronized. Notably, while the phenotypic maturation from SP1 to SP4 was achieved in 2-3 days, a small fraction of donor cells could be retained in the thymus for a longer period, during which they further matured in function. BrdU incorporation indicated that cell expansion occurred at multiple stages except SP1. Nevertheless, CFSE labeling revealed that only a limited number of cells actually divided during their stay in the medulla. As to the thymic emigration, there was a clear bias toward cells with increasing maturity, but no distinction was found between dividing and nondividing thymocytes. Collectively, these data not only provide solid evidence for a highly ordered differentiation program for CD4SP thymocytes, but they also illustrate several important features associated with the developmental process.

Abstract
The purpose of this study was to investigate the anticancer activity of 15 traditional Chinese medicines which are usually used for tumor patients in China. The MTT (methylthiazolyldiphenyl-tetrazolium bromide) method was applied to compare the antitumoral activity of the aqueous crude extracts and the ethanol crude extracts of these drugs on six human digestive tumor cell lines: human liver carcinoma cell lines (HepG-2 and SMMC-7721), human gastric cancer cell line (BGC-823), human colon adenocarcinoma cell lines (LoVo and SW-116) and esophagus adenocarcinoma cell line (CaEs-17). Most ethanol extracts demonstrated a more powerful inhibitory effect than aqueous extracts. Their IC50 values were between 10 microg/mL and 500 microg/mL. Among these drugs, Paris polyphylla Smith showed a predominant inhibitory effect on all the cell lines with IC50 values ranging from 10 microg/mL to 30 microg/mL. The findings in this study suggested that traditional Chinese medicines, especially Paris polyphylla Smith, might have potential anticancer activity on digestive cancer and its mechanism needs further study.

Abstract
AIM: To study the curative effects of docetaxel thermosensitive nano-micelles on human gastric cancer xenografts in nude mice.
METHODS: Human gastric cancer cell line BGC-823 was implanted into 48 nude mice. Different drugs were injected through the caudal vein in eight groups after establishment of the experimental model. Permanent temperature of the tumor was taken in the thermotherapy group. Tumor growth was monitored once every other day. Dynamic viewing and determining the rate of tumor regression in terms of tumor weight and volume were used to evaluate therapeutic efficacy. The side effect was evaluated through surveying all the condition and the relative variation in mouse body weight.
RESULTS: Tumor growth speed in the docetaxel thermosensitive nano-micelle thermotherapy group was significantly slower than that in the other groups. Tumor volume and weight regression in the docetaxel thermosensitive nano-micelle thermotherapy group were 81.5% and 85.4%, respectively, which were markedly higher than those of the docetaxel thermosensitive nano-micelle group (32.2% and 37.5%) and the docetaxel injection group (49.2% and 58.0%) (both P < 0.05). The drug side effects and toxicity of docetaxel thermosensitive nano-micelle thermotherapy were significantly less than those in the other groups.
CONCLUSION: Docetaxel thermosensitive nano-micelles show good inhibition of tumor growth, which indicates a favorable potential in clinical application.

Abstract
The newly generated single-positive (SP) thymocytes undergo further maturation in the thymic medulla before their emigration to the periphery. The present study was undertaken to validate a developmental program we proposed for CD4SP medullary thymocytes and to explore the mechanisms regulating this process. During mouse ontogeny, the emergence of different subsets of CD4SP thymocytes followed a strict temporal order from SP1 to SP4. Parallel to the transition in surface phenotype, a steady increase in function was observed. As further evidence, purified SP1 cells were able to sequentially give rise to SP2, SP3, and SP4 cells in intrathymic adoptive transfer and in culture. Notably, the development of CD4SP cells in the medulla seemed to be critically dependent on a functionally intact medullary epithelial cell compartment because Relb and Aire deficiency were found to cause severe blockage at the transition from SP3 to SP4. Taken together, this work establishes an ontogenetically and functionally relevant maturation program for CD4SP thymocytes. Precise dissection of this program should facilitate further inquiry into the molecular mechanisms governing normal thymocyte development and its disturbance in pathological conditions.

Abstract
OBJECTIVE To study the effect of oxaliplatin in combination with hyperthermia on angiogenesis in vitro and in vivo. METHODS MTT method was used to observe the influence of oxaliplatin on the proliferation of human umbilical vein endothelial cells (HUVEC) or human colon cancer cells (LOVO). The influence of oxaliplatin on HUVEC migration was evaluated by Transwell. Chick embryo chorioallantoic membrane (CAM) model was used to check whether the neovascularization of CAM could be suppressed in vivo. RESULTS The survival rate of HUVEC was 80.1% - 42.5% within a range of 0.5 - 16 microg/ml and was negatively correlated with the concentration (correlation coefficient was - 0. 943, P = 0.005). The survival rate of LOVO cells within those doses was more than that of HUVEC. There was a synergistic antiangiogenic effect when a combination of oxaliplatin (0.5 microg/ml, 1 microg/ml and 16 microg/ml) with hyperthermia was used while additional effect was shown by the combinatioin of oxaliplatin (2 microg/ml, 4 microg/ml and 8 microg/ml) and hyperthermia in vitro. Oxaliplatin inhibited migration of HUVEC in vitro at low doses (0.25 - 2 microg/ml), and also suppressed angiogenesis of CAM in vivo at doses of 1 -4 microg/ml. CONCLUSION The results of this experiment showed that low dose of oxaliplatin has anti-angiogenic effect in vitro, while in combination with hyperthermia has additional effect both in vivo and in vitro.

Abstract
Colorectal and gastric cancers are very common disease entities in China. Postoperative chemoradiotherapy has become the standard of care for treatment of colorectal and gastric cancers, mainly because most diagnoses are at late or advanced stages. Based on statistics from large sample studies and because of the heterogeneity among patients having the same site of cancer, there are variations in the effects and toxicity among those receiving standard chemotherapy. Tailored chemotherapy based on pharmacogenetics and pharmacogenomics has received much attention and has shown predictive potential. The present paper focuses on advances in tailored chemotherapy in colorectal and gastric cancers to determine the potential value of the drug-associated genes.

Abstract
Survivin is a protein that is highly expressed in a vast number of malignancies, but is minimally expressed in normal tissues. It plays a role as an inhibitor of cell death in cancer cells, thus facilitating the growth of these cells. In the case of gastric cancer, survivin is over-expressed in tumor cells and plays a role in the carcinogenesis process. Several studies on gastric cancer have indicated that there is a relationship between survivin expression and the ultimate behavior of the carcinoma. Since the expression pattern of survivin is selective to cancer cells, it has been described as an “ideal target” for cancer therapy. Currently, several pre-clinical and clinical trials are on-going to investigate the effects of interfering with survivin function in cancer cells as a biologic therapy. Survivin is a potentially significant protein in the diagnosis, prognosis and treatment of gastric tumors.

Abstract
The two known DP proteins, TFDP1 and -2, bind E2Fs to form heterodimers essential for high affinity DNA binding and efficient transcriptional activation/repression. Here we report the identification of a new member of the DP family, human TFDP3. Despite the high degree of sequence similarity, TFDP3 is apparently distinct from TFDP1 in function. Although TFDP3 retained the capacity to bind to E2F proteins, the resulting heterodimers failed to interact with the E2F consensus sequence. In contrast to the stimulatory effect of TFDP1, TFDP3 inhibited E2F-mediated transcriptional activation. Consistent with this observation, we found that ectopic expression of TFDP3 impaired cell cycle progression from G(1) to S phase instead of facilitating such a transition as TFDP1 does. Sequence substitution analysis indicated that the DNA binding domain of TFDP3 was primarily responsible for the lack of DNA binding ability of E2F-TFDP3 heterodimers and the inhibition of E2F-mediated transcriptional activation. Fine mapping further revealed four amino acids in this region, which were critical for the functional conversion from activation by TFDP1 to suppression by TFDP3. In conclusion, these studies identify a new DP protein and a novel mechanism whereby E2F function is regulated.

Abstract
PURPOSE The most common genitourinary malignancy in China is bladder transitional cell carcinoma (TCC). Early diagnosis of new and recurrent bladder cancers, followed by timely treatment, will help decrease mortality. There are currently no satisfactory markers for bladder cancer available in clinics. Better diagnostic methods are highly demanded. EXPERIMENTAL DESIGN In this research, we have used comprehensive expressed sequence tag analysis, serial analysis of gene expression, and microarray analysis and quickly discovered a candidate marker, urothelial carcinoma associated 1 (UCA1). The UCA1 gene was characterized and its performance as a urine marker was analyzed by reverse transcription-PCR with urine sediments. A total of 212 individuals were included in this study, 94 having bladder cancers, 33 ureter/pelvic cancers, and 85 normal and other urinary tract disease controls. RESULTS UCA1 was identified as a novel noncoding RNA gene dramatically up-regulated in TCC and it is the most TCC-specific gene yet identified. The full-length cDNA was 1,439 bp, and sequence analysis showed that it belonged to the human endogenous retrovirus H family. Clinical tests showed that UCA1 assay was highly specific (91.8%, 78 of 85) and very sensitive (80.9%, 76 of 94) in the diagnosis of bladder cancer and was especially valuable for superficial G2-G3 patients (sensitivity 91.1%, 41 of 45). It showed excellent differential diagnostic performance in various urinary tract diseases without TCC. CONCLUSIONS UCA1 is a very sensitive and specific unique marker for bladder cancer. It could have important implications in postoperative noninvasive follow-up. This research also highlights a shortcut to new cancer diagnostic assays through integration of in silico isolation methods with translational clinical tests based on RNA detection protocols.

Abstract
AIM: To investigate the expression of carcinoembryonic antigen (CEA) and its significance in the four different colon adenocarcinoma cell lines.
METHODS: Enzyme-linked immunosorbent assay (ELISA) was used to measure the expression of CEA in the cell culture medium and the immunohistochemistry was used to detect the protein expression of CEA in LS174T, SW480, LoVo and HCT-8 cell lines, separately. Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) for the expression of CEA mRNA in the four kinds of cell lines was also carried out.
RESULTS: A great variation in CEA content was found among the four kinds of colon cancer cell lines. The expression of CEA was detectable at the protein and mRNA level in LS174T and SW480 cell lines, and moreover, it was higher in the former (culture supernatant fluid: 1050 ± 25.0 ng/107 cells vs 66 ± 5.6 ng/107 cells, P < 0.0001; mRNA: 1.137 ± 0.155 vs 0.399 ± 0.135, P = 0.003). Meanwhile, CEA was negatively expressed in LoVo cells no matter at the protein or mRNA level, and HCT-8 cells were only found with weakly-positive immunohistochemical staining.
CONCLUSION: There is a great variation in CEA expression among the four kinds of human colon cancer cell lines as compared with the reported results previously. The expression change of CEA in the different cell lines may affect its in vitrobiological behavior and further lead to the uncertainty of the experiment.

Abstract
AIM: To construct and express a eukaryotic expression plasmid containing human CD40 ligand (CD40L) in human hepatocellular carcinoma cell line HepG2 for the biological function study of CD40L on HepG2 cells.
METHODS: Human CD40L cDNA was synthesized by reverse transcription-polymerase chain reaction (RT-PCR) with the specific primers from the RNA of human peripheral blood monocyte (PBMC) and directly ligated into the eukaryotic expression vector pcDNATM3.1/myc-His(-)A through digestion with specific restriction endonuclease. The recombined plasmid was transformed into the E. coli DH5α to amplify CD40L gene. Then HepG2 cells were divided into 4 groups. The cells in group A were transfected with the recombined plasmid, and group B with the blank plasmid (not containing CD40L cDNA). The cells in group C were just normally cultured, and the ones in group D weren't transfected but added G418 as the control for transfection. The expression of CD40L and CD40 were detected by RT-PCR and fluorescent activated cell sorter (FACS) in HepG2 cells, and the apoptosis, cell cycle, as well as Fas expression, were measured by FACS.
RESULTS: The full-length human CD40L cDNA was successfully cloned into the eukaryotic vector pcDNATM3.1/myc-His(-)A. The recombinant plasmid was stably transfected into group A and the rate of CD40L expression was 39.7%. There was no CD40L expression in group B and C. The rates of CD40 expression in group A, B and C were 15.4%, 31.7% and 28.5%, respectively. The apoptotic rate of group A was 45.0±0.3%, but neither group B or C showed obvious apoptosis (P <0.01). Compared with group C, a larger proportion of cells in group A was restrained at G0/G1 phase (90.4±1.3% vs 60.6±1.5%, P <0.01), while the proportions of the cells in S phase (6.32±1.0% vs 12.0±0.7%) and G2/M phase (3.3±0.7% vs 27.3±1.2%) were reduced (both P <0.01). The expression of Fas in group A showed marked increase as compared with that in group B and C (27.8±1.5% vs 3.2±0.8%, 4.2±1.0%, respectively, both P <0.01).
CONCLUSION: The eukaryotic expression plasmid pcDNATM3.1/myc-His(-)A can be stably expressed in HepG2 cell line. CD40L-induced apoptosis of HepG2 is correlated with the increased expression of Fas and cell cycle arrest.

Abstract
The HCA587 gene, identified by serological analysis of recombinant cDNA expression library (SEREX) from a hepatocellular carcinoma (HCC) patient, encodes a new member of cancer-testis antigens. HCA587 mRNA expression in normal tissues and cancers has been previously reported. To estimate its immunogenicity to induce immune response, it is essential to analyze HCA587 expression at the protein level. In this study anti-HCA587 polyclonal antibody, termed "TC-1," was generated, and the expression of HCA587 protein was assessed by immunohistochemical staining in a panel of normal and tumor tissue sections. No HCA587 protein was shown in normal tissues except germ cells in testis and Purkinji cells in cerebellum. In HCC specimens the HCA587 protein was expressed in 37.1% (26 of 70) samples. The expressed protein was either located in the cytoplasm or nucleus depending on the individual samples. More importantly, there appears to be correlation between the tumor differentiation of HCC and HCA587 protein expression, ie, the lower differentiation, the higher percentage of protein expression. Coincidentally, seroreactivity showed that the Ab specific to recombinant HCA587 protein was detected only in the sera of three patients with poorly differentiated HCCs. HCA587 antigen was also expressed in different proportions in melanoma, lymphoma, pancreatic cancer, and lung cancer.

Abstract
SDF-1/CXCR4 plays an important role in promoting survival, expansion, and differentiation of T cell progenitors. The present study investigates the mechanism by which estrogen inhibits SDF-1alpha expression in mouse thymus. Mouse estrogen enhanced transcript (mEET) is endogenously expressed in a mouse thymus epithelial cell line 1 (MTEC1). In MTEC1 cells that express the transfected sense mEET, the SDF-1alpha transcription and its chemotactic activity were profoundly inhibited. Conversely, in MTEC1 that express the transfected anti-sense mEET, the SDF-1alpha transcription and its chemotactic activity were substantially augmented. Moreover, we disclosed that mEET inhibited the production of SDF-1alpha by its suppression of NF-kappaB translocation into nucleus. Using a combinatorial induction of doxycycline (Dox) and 17beta-estradiol (E2) on the sense and anti-sense mEET transfectants, it was demonstrated that an increase of mEET expression enhanced E2-induced inhibition of SDF-1alpha production, while a blockade of mEET expression alleviated E2-induced inhibition of SDF-1alpha production. In conclusion, the E2-imposed suppression of SDF-1alpha production is partly mediated by mEET involved signaling pathway.

Abstract
AIM: In order to assess hepatocellular carcinoma associated antigen HCA587 as a potential target for immunotherapy, the Bac-to-Bac expression system was used to express recombinant protein HCA587 in insect cells.
METHODS: The cDNA encoding HCA587 gene was cloned into donor vector pFasBacHtb and recombinant pFasBac Htb-587 was transformed into competent cells DH10Bac. Recombinant Bacmid-587 was transfected into Sf9 insect cells using CELLFECTIN, Recombinant HCA587 protein was produced in Sf9 insect cells after infection with recombinant baculovirus, and was purified using Ni-NTA resin. Sera from HCC patients were also screened using recombinant protein HCA587.
RESULTS: The molecular weight of the recombinant protein HCA587 expressed in insect cells was approximately 43 kd. Western blot results proved the recombinant protein HCA587 had the similar antigenicity with its native counterpart. Serological analysis told that the rate of seroreactivity to HCA587 was not high in HCC patients.
CONCLUSION: The recombinant protein HCA587 was successfully expressed and purified using Bac-to-Bac expression system. It paved the way for generation of specific antibody and investigation of immunohistochemical analysis and immune responses of HCC in the future.

Abstract
The functional maturation process of medullary-type CD4(-)CD8(+) [CD8 single-positive (SP)] thymocytes remains largely uncharacterized. We describe a phenotypic analysis of CD8 SP medullary-type thymocytes and find a remarkable heterogeneity within this thymic cell population. While mature CD8(+) T cells in the periphery are relatively homogeneous (TCRalphabeta(+)CD3(+)Qa-2(+) HSA(-)3G11(-)6C10(-)CD69(-)), CD8 SP medullary-type thymocytes contain discrete subpopulations that can be identified by differential expression of several cell-surface markers. We have identified at least six discrete subpopulations in the subset of TCRalphabeta(+)CD3(+) CD8 SP cells in the thymus. According to the expressed phenotypes, a linear developmental pathway is predicted among these CD8 SP subpopulations as follows: 6C10(+)CD69(+)HSA(hi)3G11(+)Qa-2(-) --> 6C10(-)CD69(+)HSA(hi/int)3G11(+)Qa-2(-) --> 6C10(-)CD69(-)HSA(int)3G11(+)Qa-2(-) --> 6C10(-)CD69(-)HSA(lo)3G11(+)Qa-2(-) --> 6C10(-)CD69(-)HSA(-/lo)3G11(-)Qa-2(-) --> 6C10(-)CD69(-)HSA(-/lo)3G11(-)Qa-2(+). This study provides a framework for understanding CD8 SP T cell maturation in the thymic medulla.
