Abstract
Gallbladder cancer (GBC) is a prevalent and deadly form of bile duct cancer, associated with poor prognosis. This study aimed to investigate the genetic factors contributing to the high incidence of GBC in certain geographical regions, particularly in the Northern and Eastern parts of India. The present case-control study focused on MMP2, a gene involved in tumor progression and metastasis, as a potential candidate in GBC pathogenesis. We scanned MMP2 promoter for twelve SNPs using Sanger's sequencing and carried out a case-control study in 300 cases and 300 control samples. We found five rare variants (rs1961998763, rs1961996235, rs1391392808, rs1488656253, and rs17859816) and one nonpolymorphic SNP (rs17859817). Our results revealed a significant association between GBC and MMP2 promoter SNPs, rs243865 (Allelic-Padjusted = 0.0353) and g.55477735G > A (Allelic-Padjusted = 9.22E-05). Moreover, the haplotype "C-C-A-C-C" exhibited a significant association with GBC (P = 4.23E-05). Genotype-phenotype correlation for variant rs243865, in the GBC patient tissue samples, established that 'T' risk allele carriers had higher expression levels of MMP2. Additionally, luciferase reporter assay in HEK293T cells revealed the probable regulatory role of rs243865 variant allele 'T' in MMP2 expression. Our study uncovers the association of MMP2 promoter SNPs with GBC and their role in regulating its expression.

Abstract
HINTERGRUND UND ZIEL Bei Akne wurde eine abweichende Gewebeexpression von Matrix-Metalloproteinasen beobachtet. Ziel unserer Studie war es, die Bedeutung von Polymorphismen einzelner Nukleotide (single nucleotide polymorphisms, SNPs) in MMP-2 (-1306 C/T, rs243865) und TIMP-2 (-418 G/C, rs8179090) bei Akne und Post-Akne-Narben zu untersuchen. PATIENTEN UND METHODEN 512 Patienten (169 mit Akne ohne Narbenbildung, 319 mit atrophen Aknenarben, 24 mit hypertrophen Aknenarben) und 161 gleichaltrige Kontrollen wurden nach Erhalt der schriftlichen Einwilligungserklärung aus der Ambulanz der Hautklinik in die Studie aufgenommen. Zur Genotypisierung mittels Polymerasekettenreaktion-Restriktionsfragmentlängenpolymorphismus (PCR-RFLP) wurde venöses Blut (5 ml) entnommen. Der Schweregrad von Akne und Akne-bedingter Narbenbildung wurde bestimmt. ERGEBNISSE Männer hatten ein deutlich erhöhtes Risiko schwere Akne (p = 0,012), Akne außerhalb des Gesichts (p = 0,047) und Aknenarben außerhalb des Gesichts (p = 0,0001) zu entwickeln. Entzündliche Akne korrelierte positiv mit dem Schweregrad der Narbenbildung (p = 0,001). Die Wahrscheinlichkeit für die Bildung hypertropher Narben war bei Personen mit homozygotem CC-Genotyp von MMP-2 (-1306 C/T) gegenüber Kontrollen nicht verändert (Faktor 1,0; p = 0,05; 95 %-KI: 0,7-1,6), jedoch gegenüber Personen mit Akne ohne Narbenbildung um den Faktor 7,8 (p = 0,047; 95 %-KI: 1,0-59,9) und gegenüber Personen mit atrophen Narben um den Faktor 8,2 (p = 0,041; 95 %-KI: 1,1-59,9) erhöht. SCHLUSSFOLGERUNGEN Es wurde eine signifikante Assoziation zwischen der Bildung hypertropher Post-Akne-Narben und dem CC-Genotyp von MMP-2 (-1306 C/T) beobachtet.

Abstract
BACKGROUND AND OBJECTIVE Aberrant tissue expression of matrix metalloproteinases has been observed in acne. Our objective was to study the relevance of MMP-2 (-1306 C/T, rs243865) and TIMP-2 (-418 G/C, rs8179090) single nucleotide polymorphisms (SNP) in acne and post-acne scarring. PATIENTS AND METHODS 512 patients (169 having acne without scarring, 319 having atrophic acne scarring, 24 having hypertrophic acne scarring) and 161 age-matched controls were recruited from the Dermatology Outpatient Department after obtaining informed written consent. Venous blood (5 ml) was collected for genotyping by Polymerase Chain Reaction (PCR)-Restriction Fragment Length Polymorphism (RFLP) method. The severity of acne and acne-scarring were graded. RESULTS Males had a significantly increased risk of developing severe acne (P = 0.012), extra-facial acne (P = 0.047) and extra-facial acne scarring (P = 0.0001). The presence of inflammatory acne positively correlated with severity of scarring (P = 0.001). Subjects with a homozygous CC genotype of MMP-2 (-1306 C/T) had 1.0, 7.8 and 8.2 times the odds of developing hypertrophic scarring when compared to controls (P = 0.05, 95 % CI: 0.7-1.6), subjects having acne without scarring (P = 0.047, 95 % CI: 1.0-59.9) and subjects having atrophic scarring, respectively (P = 0.041, 95 % CI: 1.1-59.9). CONCLUSIONS A significant association was observed between hypertrophic post-acne scarring and the CC genotype of MMP-2 (-1306 C/T).

Abstract
The predominant role of IL-6 in cancer is its key promotion of tumour growth. IL-6 binds IL-6 receptor (IL-6R) and the membrane-bound glycoprotein gp130. The complex I-6/IL-6R/gp130 starts the Janus kinases (JAKs) and signal transducer and activator of transcription 3 (STAT3) or JAK/STAT3 pathway. IL-6 R exits in two forms: a membrane-bound IL-6Rα subunit (mIL-6R) that participates in classic signalling pathway and soluble IL-6R subunit (sIL-6R) engaged in trans-signalling. The pro-tumour functions of IL-6 are associated with STAT3, a major oncogenic transcription factor that triggers up-regulation of target genes responsible for tumour cell survival. IL-6 combined with TGF-β induces proliferation of pathogenic Th17 cells. The anti-tumour function of IL-6 is the promotion of anti-tumour immunity. IL-6 trans-signaling contributed to transmigration of lymphocytes in high endothelial venules (HEV). Dendritic cell (DC) secreted IL-6 in the lymph node influences the activation, distribution and polarisation of the immune response. Elevated serum levels of IL-6 and increased expression of IL-6 in tumour tissue are negative prognostic marker for patients' survival.

Oncotarget 2018; 8:45020-45029. [PMID: 28445160 PMCID: PMC5546537 DOI: 10.18632/oncotarget.16972] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2016] [Accepted: 03/14/2017] [Indexed: 12/16/2022] Open
Abstract
Numerous investigations have addressed the correlation between MMP2-1306C/T polymorphism and prostate cancer (PCa) susceptibility. However, these conclusions were controversial. Thus, we conducted this current meta-analysis based on six studies from PubMed, Embase, Cochrane Library, China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI) up to October 21st, 2016. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to evaluate the strength of the correlations. Additionally, different subgroup analyses and publication bias tests were performed. Eventually, six previous investigations consisted of 1920 cases and 1986 controls were identified and involved in this meta-analysis. Consequently, our evidence indicates a certain association between MMP2-1306C/T polymorphism and PCa risk among overall population (T vs C: OR = 1.12, 95% CI = 1.00-1.24, P = 0.040; TT+CT vs CC: OR = 1.16, 95% CI = 1.02-1.32, P = 0.026; respectively), as well as the subgroups of Asian population (T vs C: OR=1.48, 95% CI=1.13-1.94, P=0.004; TT+CT vs CC: OR = 1.66, 95% CI = 1.21-2.28, P = 0.002; respectively) and PCR-RFLP genotyped method (T vs C: OR = 1.58, 95% CI = 1.19-2.10, P = 0.001; TT+CT vs CC: OR = 1.71, 95% CI = 1.23-2.38, P = 0.001; respectively). However, no association was detected in MMP2-1306C/T polymorphism with Gleason grading or pathological stage of PCa. Our study indicates MMP2-1306 C/T polymorphism might increase PCa risk, particularly for Asian population. However, future studies comprising large cohort size from multicenter are required to confirm our conclusions.
