Purpose: This study aimed to analyze the expression and prognosis of SRY-box transcription factor 11 (SOX11) in neuroblastoma (NB), as well as the biological function and potential regulatory mechanism of SOX11 in NB. Methods: Public RNA sequencing was used to detect the expression level of SOX11. The Kaplan-Meier curve and hazard ratios (HR) were used to determine the prognostic value of SOX11 in NB. Functional analyses were performed using CCK8, wound healing assay, and transwell invasion assay. Finally, the potential target genes of SOX11 were predicted by Harmonizonme (Maayan Laboratory) and Cistrome Data Browser (Cistrome Project) database to explore the potential molecular mechanism of SOX11 in NB. Results: Compared with normal adrenal tissue, the expression of SOX11 in NB tissue was significantly upregulated. The Kaplan-Meier curve showed that high expression of SOX11 was associated with poor prognosis in children with NB (HR, 1.719; P = 0.049). SOX11 knockdown suppressed the migration capacity of SK-N-SH cells but did not affect proliferation and invasion capacity. Enhancer of zeste homolog 2 (EZH2) may be a potential downstream target gene for the transcription factor SOX11 to play a role in NB. Conclusion: The transcription factor SOX11 was significantly upregulated in NB. SOX11 knockdown suppressed the migration capacity of NB cell SK-N-SH. SOX11 may promote the progression of NB by targeting EZH2.

Aim: An epidemiological study was conducted based on an esophageal cancer patient's cohort to investigate the association of folate intake and MTHFR C677T polymorphism with the prognosis of esophageal cancer in a Chinese population. Methods: 167 patients aged 37-75 years who had histological confirmed diagnosis of esophageal squamous cell cancer were collected from Jan. 2006 to Jan. 2008. MTHFR genotypes at the C677T site were analyzed by PCR-based RFLP methods, and the folate intake was computed by multiplying the food intake (in grams) and the folate content (per gram) of food in our questionnaire. Results: We found associations between the prognosis of esophageal cancer and smoking status, T and N stages. Individuals carrying the MTHFR 677CT and TT genotypes showed a shorter survival time than with the CC genotype, with adjusted HRs (95% CI) of 1.20 (0.56-2.15) and 2.29 (1.30-4.28), respectively. Similarly, those carrying MTHFR 677T allele had a 1.86-fold risk of death. A higher folate concentration showed a significant decreased risk of death, with an HR (95% CI) of 0.45 (0.18-0.87). Individuals with high folate intake and the MTHFR 677CC genotype showed a significant decreased risk of esophageal cancer (0.43, 0.25-0.89).Conclusion: Our findings supports the hypothesis that high folate intake and active MTHFR C677T polymorphism may exert protective roles in the prognosis of esophageal cancer in the Chinese population.

Aim: To evaluate the association of glutathione S-transferases gene polymorphisms with the risk of gastric cancer, with reference to smoking and Helicobacter pylori infection. Methods: We conducted a 1:1 matched case-control study with 410 gastric cancer cases and 410 cancer-free controls. Polymorphisms of GSTM1, GSTT1 and GSTP1 were determined using PCR-CTPP. Results: The GSTM1 and GSTT1 null genotypes were significantly associated with the risk of gastric cancer after adjusting for potential confounding factors (OR=1.68, 95% CI=1.32-2.23 for null GSTM1, OR=1.73; 95% CI=1.24-2.13 for null GSTT1). The combination of null GSTM1 and null GSTT1 conferred an elevated risk (OR=2.54, 95% CI=1.55-3.39). However, no association was found for GSTP1 polymorphism The smoking modified the association of GSTM1 and GSTT1 null genotypes with the risk of gastric cancer. Conclusion: GSTM1 and GSTT1 null genotypes are associated with increased risk of gastric cancer, and smoking modifies the association.

A lysine histidine transporter (LHT) cDNA was isolated and characterized from the roots of Panax ginseng, designated PgLHT. The cDNA is 1,865 bp with an open reading frame that codes for a protein with 449 amino acids and a calculated molecular mass of 50.6 kDa with a predicted isoelectric point of 8.87. Hydropathy analysis shows that PgLHT is an integral membrane protein with 9 putative membrane-spanning domains. Multiple sequence alignments show that PgLHT shares a high homology with other plant LHTs. The expression profile of the gene was investigated by real-time quantitative polymerase chain reaction during various chemical treatments. PgLHT was up-regulated in the presence of abscisic acid, salicylic acid, methyl jasmonate, NaCl, and amino acids. To further explore the function of PgLHT gene, full-length cDNA of PgLHT was introduced into P. ginseng by Agrobacterium rhizogenes A4. The overexpression of PgLHT in the hairy roots led to an obviously increase of biomass compared to the controls, and after addition of the amino acids, the overexpressed-PgLHT hairy roots grew more rapidly than untreated controls during early stage of the culture cycle. The results suggested that the PgLHT isolated from ginseng might have role in the environmental stresses and growth response.

Aim: The present case-control study was conducted to explore the association of MTHFR gene polymorphism and relations of P16, MGMT and HMLH1 to MTHFR and folate intake. Methods: A total of 257 cases of esophageal squamous cell carcinoma confirmed by histopathological examination were collected. Genotyping of P16, MGMT and HMLH1 was accomplished by methylation-specific polymerase chain reaction (PCR) after sodium bisulfate modification of DNA and the MTHFR C677T genetic polymorphism was detected by PCR-restriction fragment-length polymorphism (PCR-RFLP). Results: The proportions of DNA hypermethylation in P16, MGMT and hMLH1 in cancer tissues were significantly higher than in paracancerous normal tissue. The proportion of hypermethylation in at least one gene was 88.5% in cancer tissue, and was also significantly higher than that in paracancerous normal tissue. Our finding showed individuals with homozygotes (TT) of MTHFR C677T had significant risk of DNA hypermethylation of MGMT in cancer tissues, with an OR (95% CI) of 3.15 (1.12-6.87). Similarly, patients with high intake of folate also showed a slight high risk of DNA methylation of MGMT, with OR (95% CI) of 2.03 (1.05-4.57). Conclusion: Our study found the P16, MGMT and hMLH1 demonstrate a high proportion of hypermethylation in esophageal squamous cell cancer cancer tissues, which might be used as biomarkers for cancer detection.

<P>Autophagy and apoptosis are critical for controlling Toxoplasma gondii (T. gondii) infection. T. gondii infection during pregnancy can damage the fetus and cause birth defects; however, the molecular mechanisms of this process are poorly understood. This study aims to determine the activities of autophagy and apoptosis as well as their regulatory mechanisms during T. gondii infection by using human umbilical cord mesenchymal stem cells (hUC-MSCs) as a model of congenital diseases. LC3B, a hallmark protein of autophagy was incrementally upregulated with the infection duration, whereas p62 was downregulated in T. gondii-infected hUC-MSCs. Concurrent to this result, the invasion of T. gondii into hUC-MSCs increased in a time-dependent manner. The expression levels of Bcl-2 family proteins including Bcl-2, Bcl-xL, Bim, Bax, Bid and Bak were not altered; however, Mcl-1 levels in hUC-MSCs were dramatically decreased upon T. gondii infection. In addition, at 24h post-infection, cleaved PARP and cleaved caspase-3 protein levels were elevated in hUC-MSCs. Importantly, Mcl-1 overexpression reduced the levels of autophagy- and apoptosis-related proteins in T. gondii-infected hUC-MSCs. Mcl-1 proteins were primarily expressed in the fraction containing mitochondria and strongly interacted with Beclin-1 under normal conditions; however, these interactions were remarkably attenuated by T. gondii infection. These results suggest that mitochondrial Mcl-1 is an essential signaling mediator regulating the activation of autophagy and apoptosis during T. gondii infection.</P>

The phase separationphenomena or cloud points (CP) behaviorof nonionic octylphenol polyoxyethylene etherwith oxyethylene glycol ether unit of 15 (OP-15) were investigated in aqueous micellar solutions containinghigh concentrations of inorganic salts including NaCl, KCl, MgCl2, CaCl2, BaCl2, AlCl3, FeCl3, Na2SO4and Na2SiO3. The change in CP induced by salts and its mechanism are discussed theoretically. In aqueous solutionscontaining high concentration of salt, for thefirst time the linear relationship between CP and saltconcentrationiswellestablishedtocharacterizethedepressionofCP.Basedonpseudophaseseparationmodel,thermodynamic parameters are estimated and adopted to further describe the phase separation process andthe interactions between OP-15 molecules or the OP-15/water interactions. Thermodynamic parametersincluding standard Gibbs energy change (DG0CP), enthalpy change (DH0CP) and entropy change (DS0CP)indicate that the additions of different salts result in the change in entropy-driven nonspontaneousprocess of phase separation. These data, which are from the compensation temperatures and the changeof molar heat capacity, also prove that different ions induce the change in the interactions betweensurfactant molecules or the surfactant–water interaction and thus affect the depression of CP. Thesefindings help with understanding the effect of inorganic salts, especially the high concentration of salt, onCP of nonionic surfactant and then broadening the application of nonionic surfactant based on CP such asthe extraction of biomaterials in biological samples derived from animals or plants, etc.

A full-length cDNA of cyclin B was isolated from ovary of the mud crab (Scylla paramamosain) in this study. This transcript encodes a polypeptide of 401 amino acids, which is highly homologous to cyclin B protein family. Reverse transcription-PCR (RT-PCR) showed that cyclin B mRNA was expressed at highest levels in ovary of the mud crab. During the ovarian maturation process, realtime RT-PCR revealed that the abundance of cyclin B mRNA increased from the second stage (early-developing stage) to the fourth stage (nearly-ripe stage) and reached the peak level at the fifth stage (ripe stage). This result indicates the identified cyclin B gene might be related to the cell proliferation in ovary, both mitotically and meiotically. Immunohistochemistry showed that cyclin B protein was localized in the cytoplasm of prophase oocytes at the second stage while enriched in the nuclei of pro-metaphase oocytes at the fourth stage. It suggests the tested cyclin B protein might play different roles in ovary at the two stages.
