[PMID: 35732318 DOI: 10.21873/cgp.20332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 04/20/2022] [Accepted: 04/26/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND/AIM Programmed cell death 6 (PDCD6) is up-regulated and highly expressed in early apoptotic cells. In several types of cancer, such as cervical, breast and lung cancers, the association of PDCD6 genotypes have been investigated. However, the contribution of PDCD6 variant genotypes to oral cancer has never been examined. The current study aimed to evaluate the contribution of the PDCD6 rs4957014 and rs3756712 genotypes to the risk of oral cancer in Taiwan. PATIENTS AND METHODS The contribution of PDCD6 genotypes to oral cancer risk was examined among 958 patients with lung cancer and 958 age- and sex-matched healthy controls by polymerase chain reaction-restriction fragment length polymorphism (PCR- RFLP). RESULTS The data showed that the hetero-variant GT and homo-variant GG genotypes of PDCD6 rs4957014 were associated with a decreased risk of oral cancer [odds ratio (OR)=0.81 and 0.39, 95% confidence interval (CI)=0.67-0.97 and 0.27-0.56, respectively]. The recessive and dominant models also showed that G carriers have protective effects (OR=0.43 and 0.72, 95% CI=0.30-0.61 and 0.61-0.87, respectively). The analysis of allelic frequency distributions showed that the G allele of PDCD6 rs4957014 was associated with reduced oral cancer risk (OR=0.71, 95% CI=0.62-0.82). There was no significant association between any PDCD6 rs3756712 genotype and oral cancer risk. In addition, the GG genotype at PDCD6 rs4957014 significantly decreased the risk of oral cancer among both males (adjusted OR=0.31, 95%CI=0.24-0.56) and females (adjusted OR=0.44, 95% CI=0.22-0.91). Furthermore, the GG genotype at PDCD6 rs4957014 significantly decreased the risk of oral cancer among smokers (adjusted OR=0.35, 95% CI=0.22-0.58), alcohol drinkers (adjusted OR=0.33, 95% CI=0.18-0.49), non-betel quid chewers (adjusted OR=0.33, 95% CI=0.17- 0.81), betel quid chewers (adjusted OR=0.34, 95% CI=0.21- 0.59), but not among never-smokers and non-alcohol drinkers. CONCLUSION The G allele carriers of PDCD6 rs4957014 may have protective effects on oral cancer risk and serve as a practical marker for early detection of oral cancer in Taiwan.

Abstract
BACKGROUND/AIM 5-methyltetrahydrofolate-homocysteine methyltransferase reductase (MTRR) is responsible for folate metabolism, and we aimed to investigate its genetic role in colorectal cancer (CRC) among Taiwanese. MATERIALS AND METHODS A total of 362 cases and 362 controls were recruited and their MTRR rs1801394 (A66G) and rs1532268 (C524T) genotypes were examined. The behavioral factors and clinicalpathological factors were also analyzed. RESULTS MTRR rs1801394 genotypes were associated with CRC risk (p for trend=0.0087). In detail, G/G genotype was associated with lower risk (p=0.0049, OR=0.39, 95%CI=0.20-0.76). As for allelic frequency analysis, G allele was also associated with decreased CRC risk (p=0.0026, OR=0.68, 95%CI=0.53-0.88). There was no significant association as for MTRR rs1532268. Among non-smokers and non-alcohol drinkers, those with G/G genotype were at 0.38- and 0.46-fold odds of having CRC. There were no significant protective effects among smokers or alcohol drinkers. CONCLUSION MTRR rs1801394 GG genotype can be a protective marker for CRC risk in Taiwan.

Abstract
BACKGROUND/AIM Matrix metalloproteinase-2 (MMP-2) plays a critical role in the regulation of the extracellular matrix; however, its genotypes have seldom been examined in gastric cancer (GC). This study aimed to investigate the contribution of MMP-2 promoter -1306 (rs243865) and -735 (rs2285053) genotypes to GC risk in a cohort of Taiwanese individuals. MATERIALS AND METHODS This study included 121 GC cases and 363 age- and sex-matched controls. The genotypes of MMP-2 were determined by typical polymerase chain reaction-restriction fragment length polymorphism. RESULTS The genotypic and allelic frequency analysis showed that MMP-2 rs243865 variant genotypes decreased the risk of GC. Stratification analysis showed that MMP-2 rs243865 genotypes associate with smoking, alcohol drinking, and Helicobacter pylori infection status to confer personal susceptibility to GC. There is no such association for MMP-2 rs2285053 genotype with GC risk. CONCLUSION The MMP-2 rs243865 genotypes may serve as a novel predictive marker for GC personal susceptibility among Taiwanese.

Abstract
BACKGROUND/AIM Gadolinium has been reported to cause liver lobular necrosis and nephrogenic systemic fibrosis. However, its toxicity to the skin remains unknown. This study aimed to investigate the effect of a high dose of gadolinium-based contrast agent gadodiamide on the human keratinocyte HaCaT cell line. MATERIALS AND METHODS Cell viability was assessed using MTT assay, and autophagy was assessed using acridine orange and LysoTracker Red staining. Western blotting was performed to verify the changes in Bcl2 and Bax levels. RESULTS The viability of HaCaT cells was significantly suppressed after gadodiamide treatment. Interestingly, gadodiamide caused autophagic vacuoles, whereas the autophagy inhibitors 3-methyladenine and chloroquine significantly alleviated autophagic cell death. Simultaneously, gadodiamide induced apoptosis, which was reduced by caspase inhibitors. Gadodiamide also inhibited Bcl-2 expression and promoted Bax expression. CONCLUSION Gadodiamide induced both autophagy and apoptosis in HaCaT cells. Physicians should carefully assess the gadodiamide dosage used clinically.

Prognostic significance of circulating insulin growth-like factor 1 and insulin growth-like factor binding protein 3 in renal cell carcinoma patients. Am J Cancer Res 2022; 12:852-860. [PMID: 35261807 PMCID: PMC8899987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Accepted: 02/04/2022] [Indexed: 06/14/2023] Open
Abstract
Insulin growth-like factor-1 (IGF-1) and its main binding protein insulin growth-like factor binding protein 3 (IGFBP-3) play important roles in cancer development and progression. We hypothesize that circulating IGF-1 and IGFBP-3 may have significant prognostic values in renal cell carcinoma (RCC) patients. We used 1,010 histologically confirmed RCC patients in this case series study to test this hypothesis. We constructed a weighted genetic risk score (GRS) using a large panel of genome-wide association study (GWAS)-identified single nucleotide polymorphisms (SNPs) to predict circulating IGF-1 and IGFBP-3 level, respectively. We analyzed the associations of the GRS with the prognosis of RCC patients using multivariate Cox proportional hazards model. We found significant associations between genetically predicted circulating IGF-1 level, but not IGFBP-3, and RCC prognosis. RCC patients with better prognosis had significantly higher baseline circulating IGF-1 level than those with worse prognosis. Dichotomized at the median value of GRS, patients with high IGF-1 exhibited significantly lower risks of recurrence (HR=0.81, 95% CI, 0.65-0.99, P=0.045) and death (HR=0.74, 95% CI, 0.60-0.91, P=0.004). If patients were dichotomized at the 75% value of GRS, those with the highest quarter of GRS had 27% lower risk of recurrence (OR=0.73, 95% CI, 0.55-0.96, P=0.025) and 34% lower risk of death (OR=0.66, 95% CI, 0.50-0.87, P=0.003) than the other three quarters of patients. High IGF-1/IGFBP-3 ratio was also associated with reduced risks of recurrence and survival. In conclusion, high circulating IGF-1 level and IGF-1/IGFBP-3 ratio at diagnosis is associated with better prognosis in RCC patients.

Abstract
BACKGROUND/AIM Acute lymphoblastic leukemia (ALL) is frequent among children. Few studies have researched the relationship between maternally expressed gene 3 (MEG3) and cancer risk. We hypothesized long non-coding RNA MEG3 polymorphisms might influence the risk of childhood ALL. MATERIALS AND METHODS In a total of 266 patients with childhood ALL and 266 healthy controls, genotypes of MEG3 rs7158663, rs3087918, rs11160608 and rs4081134 single nucleotide polymorphisms were investigated for their associations with childhood ALL. RESULTS MEG3 rs7158663 AG and AA genotypes were significantly associated with ALL [odds ratio=1.61 (95% confidence interval=1.12-2.31) and 2.21 (1.16-4.22), respectively]. The A allele also exhibited a statistical association with higher risk of ALL (p=0.0015). There was no positive association as for rs3087918, rs11160608 or rs4081134. Interestingly, a significant interaction between MEG3 rs7158663 and age (≥3.5 years) and gender (male) was found. CONCLUSION MEG3 rs7158663 AG/AA genotypes were associated with higher susceptibility to childhood ALL. These novel findings should be validated in larger populations and different ethnicities.

Abstract
DNA methylation plays important roles in prostate cancer (PCa) development and progression. African American men have higher incidence and mortality rates of PCa than other racial groups in U.S. The goal of this study was to identify differentially methylated CpG sites and genes between clinically defined aggressive and nonaggressive PCa in African Americans. We performed genome-wide DNA methylation profiling in leukocyte DNA from 280 African American PCa patients using Illumina MethylationEPIC array that contains about 860K CpG sties. There was a slight increase of overall methylation level (mean β value) with the increasing Gleason scores (GS = 6, GS = 7, GS ≥ 8, P for trend = 0.002). There were 78 differentially methylated CpG sites with P < 10-4 and 9 sites with P < 10-5 in the trend test. We also found 77 differentially methylated regions/genes (DMRs), including 10 homeobox genes and six zinc finger protein genes. A gene ontology (GO) molecular pathway enrichment analysis of these 77 DMRs found that the main enriched pathway was DNA-binding transcriptional factor activity. A few representative DMRs include HOXD8, SOX11, ZNF-471, and ZNF-577. Our study suggests that leukocyte DNA methylation may be valuable biomarkers for aggressive PCa and the identified differentially methylated genes provide biological insights into the modulation of immune response by aggressive PCa.

Abstract
BACKGROUND/AIM The tissue inhibitor of metalloproteinase-2 (TIMP-2) is a critical inhibitor of matrix metalloproteinases (MMPs). Along with MMPs, TIMP-2 regulates the breakdown and remodeling of the extracellular matrix (ECM) and basement membranes. This study investigated the role of genotypes of the TIMP-2 -418G/C (rs8179090) single nucleotide polymorphism on lung risk. MATERIALS AND METHODS A total of 358 lung cancer patients and 716 healthy subjects were recruited in this study. Genotypes were identified via the polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The distribution of alleles and genotype frequencies of TIMP-2 -418G/C genotypes between the two groups were compared and no statistically significant difference (p>0.05) was found. The heterozygous and homozygous variant genotypes showed no differential distribution between the control and case groups (p>0.05). CONCLUSION TIMP-2 -418G/C variants might not be associated with lung cancer susceptibility and could not serve as predictors.

Abstract
BACKGROUND/AIM The clinical use of arsenic trioxide (As2O3) is hampered due to its cardiotoxicity. Therefore, it is critical to prevent As2O3-induced loss of endothelial integrity. The purpose of this study was to examine As2O3-induced endothelial dysfunction and evaluate the efficacy of crocetin on reversing As2O3-induced cardiotoxicity. MATERIALS AND METHODS Cultured human umbilical vein endothelial cells (HUVECs) were used to examine As2O3-induced oxidative stress, apoptosis, production of reactive oxygen species (ROS) and DNA adducts. In addition, the impact of crocetin on As2O3-induced cardiotoxicity was evaluated. RESULTS As2O3 decreased the viability of HUVEC cells and led to apoptosis. Additionally, As2O3 elevated NADPH oxidase activity, and the levels of intracellular ROS. Furthermore, the formamidopyrimidine DNA-glycosylase- and endonuclease III-digestible adducts were induced by As2O3 Crocetin treatment reversed the As2O3-induced reduction in cell viability, the induction of apoptosis, the activation of NADPH oxidase activity, ROS levels and DNA adducts. CONCLUSION Crocetin protects from As2O3-induced cardio-toxicity.

Abstract
BACKGROUND/AIM This study investigated whether genetic variations in cyclin D1 (CCND1) are associated with susceptibility to childhood acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS A total of 266 childhood ALL cases and 266 healthy controls were genotyped for CCND1 rs9344 and rs678653. RESULTS There was a significant difference in the genotypic distribution of rs9344 between childhood ALL patients and healthy controls (p=0.0077). Compared to the AA genotype, AG and GG genotypes were associated with significantly decreased risks of childhood ALL with odds ratio (OR) of 0.65 [95% confidence interval (CI)=0.44-0.94, p=0.0234] and 0.45 (95%CI=0.26-0.78, p=0.0040), respectively. Supporting this, allelic frequency distributions between childhood ALL patients and controls was significantly different (OR=0.68, 95%CI=0.53-0.88, p=0.0025). There was no significant difference in the genotypic and allelic distributions of rs678653 between cases and controls. CONCLUSION CCND1 rs9344, but not rs678653, may serve as a predictive marker of susceptibility for childhood ALL.

Abstract
BACKGROUND/AIM Breast cancer incidence is highest among women worldwide, and practical markers for personalized therapeutic strategies are few. Interleukin-12 (IL-12) is a cytokine that is reported to be significantly lower in healthy controls than breast cancer cases, however, its genotypic contribution to carcinogenesis has never been revealed in breast cancer. We examined whether IL-12A rs568408 and rs2243115 genotypes contribute to elevated breast cancer risk and summarized related literature among other cancers. MATERIALS AND METHODS IL-12A genotypic profiles were determined among 1,232 breast cancer cases and 1,232 healthy controls via polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The variant genotypes of IL-12A rs568408 and rs2243115 were not found to be significantly associated with elevated breast cancer risk (both p>0.05). CONCLUSION IL-12A rs568408 and rs2243115 genotypes may not serve as good predictors of breast cancer risk.

Abstract
AIM There is very little literature reporting the association of matrix metalloproteinase-1 (MMP1) with personal susceptibility to bladder cancer. In the current study, we carried out the first examination of the contribution of MMP1 rs1799750 to bladder cancer risk in Taiwanese. MATERIALS AND METHODS A total of 375 bladder cancer cases and 375 healthy controls were genotyped for MMP1 rs1799750 via polymerase chain reaction-restriction fragment length polymorphism methodology and this was evaluated for association with clinicopathological factors. RESULTS The frequencies of MMP1 rs1799750 2G/2G, 1G/2G, and 1G/1G genotypes were 35.7%, 44.8% and 19.5% in the group with bladder cancer and 32.5%, 46.4%, and 21.1% in the healthy control group (p for trend=0.6362). The odds ratios (ORs) for bladder cancer risk after adjusting for age and gender for those carrying 1G/2G and 1G/1G genotypes at MMP1 rs1799750 were 0.88 (95% CI=0.62-1.24, p=0.4357) and 0.83 (95% CI=0.61-1.26, p=0.3990), respectively, compared with the wild-type 2G/2G genotype. In allelic frequency analysis, the adjusted OR for those carrying the 1G allele at MMP1 rs1799750 was 0.87 (95% CI=0.71-1.23, p=0.3479) compared to those people carrying a 2G allele. CONCLUSION Our findings indicated that the genotypes at MMP1 rs1799750 appear to play little role in determining personal susceptibility to bladder cancer for Taiwanese.

Abstract
Insulin growth factor-1 (IGF-1) plays important roles in carcinogenesis. Previous studies have linked circulating IGF-1 and its main binding protein, insulin-like growth factor-binding protein-3 (IGFBP-3), to cancer risks. However, no study has been conducted in soft tissue sarcoma (STS). In this study, we investigated the relationship of genetically predicted circulating IGF-1 and IGFBP-3 with STS risks. Recent large genome-wide association studies (GWAS) have identified 413 single nucleotide polymorphisms (SNPs) associated with IGF-1 and 4 SNPs associated with IGFBP-3. We genotyped these SNPs in 821 patients and 851 healthy controls. We constructed weighted genetic risk scores (GRS) to predict circulating IGF-1 and IGFBP-3. We determined the associations of individual SNPs and GRS with the risks of STS using multivariate logistic regression analysis. We found high genetically predicted circulating IGF-1 and IGFBP-3 were both associated with increased STS risks. Dichotomized at the median values of IGF-1 and IGFBP-3 in controls, individuals with high level of IGF-1 exhibited a 27% increased risk of STS (odds ratio [OR]=1.27, 95% confidence interval [CI]=1.04-1.54, P=0.017), whereas the OR for high IGFBP-3 was 1.45 (95% CI=1.20-1.77, P<0.001). Interestingly, the significant association between IGFBP-3 and STS risk was only evident in women (OR=1.88, 95% CI=1.42-2.49, P<0.001), but not in men (OR=1.00, 95% CI=0.75-1.33, P=0.992). In stratified analyses by major STS subtypes, the strongest associations were observed in angiosarcoma for IGF-1, leiomyosarcoma for IGFBP-3, and gastrointestinal stromal tumors for IGFBP-3 in women. In conclusion, high circulating IGF-1 and IGFBP-3 levels were both associated with increased STS risks.

Abstract
Insulin-like growth factors (IGF) play important roles in carcinogenesis. The associations of circulating IGF-1 and insulin-like growth factor-binding protein-3 (IGFBP-3) with the risks of bladder cancer remain unclear. In this large case control study of 2011 bladder cancer cases and 2369 heathy controls, we assessed the associations of circulating IGF-1 and IGFBP-3 with bladder cancer risks using a Mendelian randomization approach, which uses genetic variants as instruments to study causal relationship between risk factors and diseases. We first constructed a weighted genetic risk score (GRS) predictive of circulating IGF-1 and IGFBP-3 using 413 genome-wide association study-identified single nucleotide polymorphisms (SNPs) associated with IGF-1 and four SNPs with IGFBP-3, respectively. We found that higher GRS for IGF-1 was associated with a significantly reduced bladder cancer risk (odds ratio [OR] = 0.66 per SD increase, 95% confidence interval [CI], 0.54-0.82, p < 0.001). We then used a summary statistics-based MR method, inverse-variance weighting (IVW), and found a similar risk estimate (OR = 0.67 per SD increase, 95% CI = 0.54-0.83, p < 0.001). When we categorized individuals into high and low IGF-1 groups using the median GRS value in the controls, the high GRS group had a 21% reduced bladder cancer risk (OR = 0.79, 95% CI = 0.70-0.89) compared to the low GRS group. Genetically predicted circulating IGFBP-3 was not associated with bladder cancer risk. In conclusion, our data demonstrated for the first time a strong inverse relationship between circulating IGF-1 level and bladder cancer risk.

Anticancer Res 2021; 41:3309-3315. [PMID: 34230126 DOI: 10.21873/anticanres.15118] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 06/09/2021] [Accepted: 06/10/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND/AIM Matrix metalloproteinase 9 (MMP9) is highly expressed in gastric cancer but the role of MMP9 is unclear. This study aimed at revealing the association of MMP9 promoter rs3918242 genotypes with gastric cancer risk. MATERIALS AND METHODS MMP9 rs3918242 genotypes of 121 patients with gastric cancer and 363 healthy individuals were examined by polymerase chain reaction-restriction fragment length polymorphism methodology using serum samples. RESULTS MMP9 rs3918242 TT genotype carriers had an elevated gastric cancer risk compared to wild-type CC carriers (odds ratio=3.92, 95% confidence interval=1.28-11.99; p=0.0103). Patients with CT/TT genotypes were at higher risk of metastasis (p=0.0178) than those with CC. No correlation was found between MMP9 rs3918242 genotype and gastric cancer risk with smoking or alcohol behavior, nor Helicobacter pylori infection. No correlation was observed for MMP9 rs3918242 genotypic distributions with age, gender, or body mass index. CONCLUSION Carrying a T allele for MMP9 rs3918242 may be predictive for higher gastric cancer risk, and as a predictor for higher risk of metastasis.

In Vivo 2021; 35:2041-2046. [PMID: 34182479 DOI: 10.21873/invivo.12473] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Revised: 05/03/2021] [Accepted: 05/04/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND/AIM The molecular mechanisms underlying the association between cell cycle and asthma are poorly understood, and cyclin D1 (CCND1) is found to be upregulated in asthma airway smooth muscle. We investigated whether the most frequently examined functional variants in CCND1 determine asthma susceptibility. MATERIALS AND METHODS We genotyped 651 participants for single-nucleotide polymorphisms (SNPs) at rs9344 and rs678653 on CCND1 and assessed the association of these SNPs with asthma risk. RESULTS Significant differences were found in the distributions of genotypic (p=0.0064) and allelic (p=0.0021) frequencies of CCND1 rs9344. In addition, AG or GG carriers had 0.63- or 0.48-fold adjusted odds ratios for asthma risk (95%confidence intervals=0.48-0.92 and 0.22-0.78, respectively) than those who carried the AA wildtype. CONCLUSION Our results suggest that cell cycle regulation may play a role in asthma initiation and development, and the CCND1 rs9344 genotype may serve as an early detection marker for asthma.

Abstract
BACKGROUND/AIM Matrix metalloproteinase 2 (MMP2) is reported to be overexpressed in asthma; however, its genotypic contribution to asthma is not well studied. Therefore, we examined the association of MMP2 genotypes with asthma risk among Taiwanese. MATERIALS AND METHODS One hundred and ninety-eight asthma patients and 453 non-asthmatic subjects were determined with respect to their MMP2 -1306 (rs243845) and -735 (rs2285053) genotypes. RESULTS CT and TT at MMP2 rs243845 are 17.7% and 1.5% among asthma cases, whereas their presence in healthy subjects is at 28.1% and 2.4%, respectively (p for trend=0.0118). In detail, the CT genotype in MMP2 rs243845 was associated with a decreased asthma risk [adjusted odds ratio (OR)=0.57, 95% confidence interval (CI)=0.37-0.78, p=0.0040], and the T allele conferred a significantly lower asthma risk compared to the wild-type C allele (adjusted OR=0.55, 95%CI=0.43-0.77, p=0.0042). No significance was found for MMP2 rs2285053. CONCLUSION The genotype of CT in MMP2 rs243845 may serve as a novel biomarker in determining susceptibility to asthma in Taiwan.

Abstract
BACKGROUND Salvia miltiorrhiza is a medical herb for human disorders including cardiovascular diseases and cancer. However, the interactions between Salvia miltiorrhiza and its endophytes are largely unknown. The current study aimed at identifying its endophytic fungi and examining their inhibitory effects on anti-pathogenic fungus. MATERIALS AND METHODS Distinct species of endophytic fungi were isolated from the roots of Salvia miltiorrhiza, cultured, sequenced, aiming to predict their taxonomical structures. Meanwhile, extracts from each endophytic fungus fermentations were isolated, compared and evaluated on the inhibitory efficacies on five pathological fungi, Cercospora nicotianae, Phoma arachnidicola, Staphylococcus, Phytophthora eggplant, and Rhizoctonia cerealis. RESULTS A total of 34 strains of endophytic fungi were obtained from Salvia miltiorrhiza. Among them, SX19 and C. Gloeosporioids exhibited the most effective inhibitions on five pathogenic fungi. CONCLUSION The anti-fungal activities of the endophytic fungus from Salvia miltiorrhiza were confirmed for the first time, and this may benefit crop quality and production in the future.

Abstract
BACKGROUND/AIM Chitinase 3-like 1 (CHI3L1) is overexpressed in asthma, and negatively associated with forced expiratory volume in the first second. This study aimed at evaluating whether CHI3L1 genotypes affect asthma risk. MATERIALS AND METHODS The blood samples of 198 asthma patients and 453 control subjects were collected, and the genotypic patterns of CHI3L1 -131C/G (rs4950928) and -247G/A (rs1262491437) were examined. RESULTS The percentages of CG and GG at CHI3L1 -131C/G were 32.8% and 7.6% among the asthma cases, respectively, significantly higher than the 23.8% and 3.1% among the non-asthmatic healthy subjects (p for trend=0.0009). The allelic frequency distribution analysis showed that the G allele at CHI3L1 - 131C/G conferred a significantly higher asthma risk than the wild-type C allele (p<0.0001). The genotypic and allelic frequency analyses for CHI3L1 -247G/A did not show any significant difference. CONCLUSION The G allele at CHI3L1-131C/G serves as a biomarker in determining personal susceptibility to asthma in Taiwan.

Abstract
BACKGROUND/AIM Arsenic trioxide (As2O3) is an environmental pollutant. However, the detailed mechanisms about As2O3-induced loss of endothelial integrity are unknown. This study aimed at investigating how As2O3 causes endothelial dysfunction and whether baicalin can reverse such dysfunction. MATERIALS AND METHODS Human umbilical vein endothelial cells (HUVECs) were used to examine As2O3-induced oxidative stress, and apoptosis. The influence of baicalin on As2O3-induced endothelial dysfunction were investigated. RESULTS The viability of HUVECs was inhibited by As2O3 and cells underwent apoptosis. As2O3 treatment increased NADPH oxidase activity, and elevated the level of reactive oxygen species (ROS). Formamidopyrimidine DNA-glycosylase- and endonuclease III-digestible adducts were accumulated. Baicalin reversed As2O3-induced apoptosis and As2O3-suppressed cell viability. Baicalin caused a decrease in NADPH oxidase activity, and re-balanced the ROS level. As2O3-induced formamidopyrimidine DNA-glycosylase- and endonuclease III-digestible adducts were down-regulated. CONCLUSION Baicalin was found to have the potential capacity to protect endothelial cells from As2O3-induced cytotoxicity.

Abstract
BACKGROUND/AIM Interleukin-16 (IL-16) is reported to play an important role in inflammation, carcinogenesis and tumoricidal processes, however, the contribution of IL-16 genotype to oral carcinogenesis is still largely unrevealed. Thus, the study aimed to investigate the contribution of IL-16 genotypes to Taiwan oral cancer risk. MATERIALS AND METHODS The genotypes of IL-16 rs4778889, rs11556218, and rs4072111 were revealed among 958 oral cancer cases and 958 control subjects by polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP). RESULTS First, the distributions of genotypic (p=0.0004) and allelic (p=0.0001) frequencies of IL-16 rs11556218 were significantly different between the case and control groups. In detail, the frequencies of IL-16 rs11556218 TG and GG were 28.1 and 5.8%, respectively, among oral cancer patients, significantly higher compared to those among controls (25.0% and 2.7%, respectively). Second, no difference was observed regarding IL-16 rs4778889 or IL-16 rs4072111. Last, there was a synergistic effect of betel quid chewing behavior and risky IL-16 rs11556218 genotype on oral cancer risk. CONCLUSION The study indicates that the IL-16 rs11556218 G allele synergistically interacts with betel quid chewing behavior, contributing to increased risk of oral cancer in Taiwanese.

Abstract
Telomeres play important roles in cancer initiation and progression. Leukocyte telomere length (LTL) has been associated with the risk and prognosis of several cancers, but its association with prostate cancer (PCa) prognosis in African Americans (AAs) has not been reported. In this study, we measured relative LTL from 317 AA PCa patients and assessed its associations with aggressive disease characteristics at diagnosis and biochemical recurrence (BCR) after radical prostatectomy and radiotherapy. LTL was shorter in patients with higher Gleason scores (GS) at diagnosis. Dichotomized into short and long LTL groups, patients with short LTL exhibited a 1.91-fold (95% confidence interval, CI, 1.14-3.20, P = 0.013) increased risk of being diagnosed with high-risk disease (GS =7 [4 + 3] and GS ≥8) than those with long LTL in multivariable logistic regression analysis. Moreover, shorter LTL was significantly associated with an increased risk of BCR (hazard ratio = 1.68, 95% CI, 1.18-11.44, P = 0.024) compared with longer LTL in localized patients receiving prostatectomy or radiotherapy in multivariable Cox analysis. Kaplan-Meier survival analysis showed patients with short LTL had significantly shorter BCR-free survival time than patients with long LTL (Log rank P = 0.011). In conclusion, our results showed for the first time that LTL was shorter in PCa patients with higher GS and short LTL was associated with worse prognosis in AA PCa patients receiving prostatectomy or radiotherapy.

Resveratrol inhibited the metastatic behaviors of cisplatin-resistant human oral cancer cells via phosphorylation of ERK/p-38 and suppression of MMP-2/9. J Food Biochem 2021; 45:e13666. [PMID: 34008860 DOI: 10.1111/jfbc.13666] [Citation(s) in RCA: 74] [Impact Index Per Article: 24.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 01/27/2021] [Accepted: 02/01/2021] [Indexed: 12/19/2022]
Abstract
Cisplatin resistance is a major clinical problem in the clinical management of oral squamous cell carcinoma (OSCC) patients. Resveratrol is a natural phytoestrogen with antitumor activities. Whether resveratrol can overcome cisplatin resistance and prevent metastasis in OSCC cells is not known. In this study, we first examined the anti-metastatic capacity of resveratrol and then explored the underlying mechanisms using a cisplatin-resistant human OSCC cell line (CAR). The results demonstrated that at a non-toxic dose range (25 to 75 µM), 24-hr treatment of resveratrol was able to suppress the migration and invasion capacities of CAR cells dose dependently. Interestingly, 50 µM resveratrol treatment could significantly down-regulate the expression of the phosphorylated forms of ERK and p-38, in addition to those of MMP-2 and MMP-9. At the same time, the expression levels of phosphorylated ERK together with those unphosphorylated forms of ERK, p38, and JNK were all insignificantly altered. In conclusion, the signaling cascade for resveratrol's suppression of cisplatin-resistant human oral cancer CAR cells was revealed and summarized. Also the rapid effectiveness in suppressing metastatic behaviors of drug-resistant oral cancer cells of non-toxic resveratrol might extend its application to the drug-resistant oral cancer treatment in the near future. PRACTICAL APPLICATIONS: Based on the evidence we provided in the study, we have proposed a model recording the possible pathway for resveratrol inhibiting the metastasis of cisplatin-resistant oral cancer cells. We suppose this signaling pathway may work in other cancer cell lines, and can be helpful in full understanding of the drug-resistance.

Abstract
BACKGROUND/AIM Xeroderma pigmentosum complementation group C (XPC) is reported to play important roles in DNA integrity and genomic instability, however, the contribution of XPC to oral carcinogenesis is largely uncertain. Therefore, we aimed at examining the contribution of XPC genotypes to oral cancer. MATERIALS AND METHODS The genotypes of XPC rs2228001 and rs2228000 were examined among 958 oral cancer patients and 958 control subjects by polymerase chain reaction-restriction fragment length polymorphism methodology and corresponding DNA repair capacity was checked. RESULTS First, the percentages of XPC rs2228001 AC and CC were higher among oral cancer patients than controls. Second, no significant association was observed regarding XPC rs2228000. Third, there was a synergistic influence of smoking and betel quid chewing behaviors and XPC rs2228001 genotype on oral cancer risk. Last, functional experiments showed DNA repair capacity was lower for AC/CC carriers than AA carriers. CONCLUSION XPC rs2228001 C allele, which was associated with decreased DNA repair capacity, may interact with smoking and betel quid chewing behaviors on oral cancer risk.

Abstract
BACKGROUND/AIM Triple negative breast cancer (TNBC) is characterized by increased recurrence and poor survival. Mounting evidence suggests that interleukin-10 (IL-10) plays a role in carcinogenesis, however, little is known about the contribution of IL-10 to TNBC. The study evaluated the contribution of IL-10 promoter A-1082G (rs1800896), T-819C (rs3021097), A-592C (rs1800872) genotypes to the risk of TNBC. MATERIALS AND METHODS IL-10 genotypes were examined among 1,232 breast cancer patients and 1,232 controls and evaluated. RESULTS The percentages of AG and GG for IL-10 A-1082G genotypes were higher in the breast cancer patient group than in the control group. The GG genotype carriers were of higher risk for breast cancer [odds ratio (OR)=2.02, 95% confidence interval (CI)=1.28-3.21, p=0.0021]. Interestingly, G allele carriers were of higher risk of TNBC (OR=1.25, 95%CI=1.07-1.46, p=0.0050). CONCLUSION The G allele of IL-10 A-1082G genotype may serve as a predictor for TNBC risk. The finding should be validated in other populations.
