Matrix metalloproteinase 11 (stromelysin-3) has recently been reported to play a key role in human tumor progression and poor clinical outcome. The aim of this study was to investigate the significance of matrix metalloproteinase 11 expression in gastric cancer. Using real-time quantitative reverse-transcription polymerase chain reaction analysis and immunohistochemistry, we studied matrix metalloproteinase 11 expression levels in non-malignant gastric tissues and in gastric cancer tissues. The association between matrix metalloproteinase 11 expression levels and tumor stage and grade, as well as metastatic potential, was analyzed. Our results show that matrix metalloproteinase 11 expression was significantly higher in gastric cancer specimens compared with nonmalignant tissues at both transcriptional and protein levels, indicating its positive role in the development of gastric cancer. In addition, increased matrix metalloproteinase 11 expression levels were associated with advanced-stage and high-grade tumors, suggesting its involvement in the progression of gastric cancer. More importantly, increased matrix metalloproteinase 11 expression in gastric cancer specimens was correlated with increased expression of IGF-1, a molecule known to stimulate the proliferation, enhanced survival, and migration of cancer cells. Our results demonstrate that matrix metalloproteinase 11 is a novel factor in the development and progression of gastric cancer and suggest that matrix metalloproteinase 11 is a marker for advanced gastric cancer.

The peroxisome proliferator-activated receptor-γ2 (. PPARγ2) gene has been implicated in the etiology of hypertension. However, the results have been inconsistent. In this study, a meta-analysis was performed to assess the association of . PPARγ2 rs1801282 polymorphism with hypertension risk. Published literature from PubMed, Embase databases, CNKI and Wanfang Data were retrieved. Pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using fixed- or random-effects model. Eight studies (1865 cases and 1416 controls) for rs1801282 polymorphism were identified. The results suggested that rs1801282 polymorphism Ala allele might be protective for hypertension among East Asians (Ala/Ala. +. Pro/Ala vs. Pro/Pro: OR. =. 0.63, 95%CI 0.46-0.86) but not among Caucasians (Ala/Ala. +. Pro/Ala vs. Pro/Pro: OR. =. 0.72, 95%CI 0.38-1.38). The results indicated the significant association of . PPARγ2 rs1801282 polymorphism with hypertension susceptibility among East Asians. © 2012 Elsevier B.V.

Epigenetics is the study of inherited changes in phenotype or gene expression that do not alter DNA sequence. Recently, scientists have focused their attention on 5-hydroxymethylcytosine (5hmC), a newly discovered epigenetic marker, also known as sixth DNA base of the genome. In mammals, this novel epigenetic marker is derived from 5-methylcytosine (5mC) in a process catalyzed by ten-eleven translocation (TET) enzymes. Although 5hmC has only been subjected to study for a short while, a great deal of data has been accumulated regarding its generation, distribution, demethylation, function, and disease implications. All this information suggested that 5hmC acts not only as an intermediate in the DNA demethylation process but also as an independent epigenetic marker, playing an important role in the regulation of gene expression. This review focuses on recent progress in the study of the relationship between 5hmC and human diseases, such as cancer and Rett syndrome (RTT). © 2014 Elsevier B.V.

Autophagy has become one of the most important mechanisms of chemotherapy resistance by supporting the survival of tumor cells under metabolic and therapeutic stress. Here, we showed that miR-22 inhibited autophagy and promoted apoptosis to increase the sensitivity of colorectal cancer (CRC) cells to 5-fluorouracil (5-FU) treatment both in vitro and in vivo. B-cell translocation gene 1 (BTG1) was identified as a new target of miR-22, which could reverse the inhibition of autophagy induced by miR-22. Thus, miR-22 may function as an important switch between autophagy and apoptosis to regulate 5-FU sensitivity through post-transcriptional silencing of BTG1. Promisingly, miR-22 could be considered as both a predictor of 5-FU sensitivity for personalized treatment and a therapeutic target for colorectal cancer. © 2014 Elsevier Ireland Ltd.

Piwi-interacting RNAs (piRNAs), new non-coding small RNAs, are association with chromatin organization, messenger RNA stability and genome structure. However, the roles of piRNA in carcinogenesis are not clearly defined. By using real-time reverse transcription-polymerase chain reaction technology, we found that the expression level of piR-823 in gastric cancer tissues was significant lower than that in non-cancerous tissues. After increase the level of piR-823 in gastric cancer cells, cell growth was inhibited. The results of xenograft nude mice model confirmed its tumor suppressive properties. All of the evidences indicated that piR-823 play a crucial role in the occult of gastric cancer. © 2011 Elsevier Ireland Ltd.

Gossypiboma is a serious and potentially dangerous medico-legal problem.We present a case of lower abdominal gossypiboma that presented as an abdominal cystic mass mimicking ovarian teratoma. The mass and the adhesive intestine loop were en blocly resected. The cut section confirmed gossypiboma diagnosis.The present experience and related literature results indicate that gossypiboma should always be kept in mind for the differential diagnosis of cystic soft-tissue mass detected in patients with a prior operation history despite its rarity and diagnosis difficulty. Once detected or suspected, appropriate surgical intervention should be performed promptly. Most importantly, preventing is much more crucial than curing in order to avoid this highly undesired potential complication.

Zinc finger protein X-linked (ZFX) is a zinc finger transcription factor and plays a significant role in the self-renewal ability of embryonic stem cells and various cancers. However, its expression and function in colorectal cancer (CRC) remain unclear. In the present study, we evaluated the expression of ZFX in CRC using quantitative polymerase chain reaction (qPCR), western blot analysis and immunohistochemistry (IHC), and further explored its potential functions in CRC cell lines using cell counting kit-8 and Transwell invasion assays. qPCR and western blot analysis revealed that ZFX was significantly upregulated in CRC tissues; IHC further confirmed this finding, revealing that higher expression of ZFX was significantly associated with larger tumor size (P=0.01), higher pathological stage (P=0.02), depth of invasion (P=0.047), lymph node invasion (P=0.02) and higher American Joint Committee on Cancer (AJCC) stage (P=0.04). CRC patients with higher ZFX expression also exhibited significantly shorter survival times (P=0.019). Moreover, knockdown of ZFX significantly suppressed proliferation and invasion in CRC cell lines HCT116 and LoVo. These results suggest that ZFX plays a notable role in CRC tumorigenicity and may serve as a novel marker and therapeutic target for CRC. © 2015, Spandidos Publications. All rights reserved.

Craniofacial bone marrow mesenchymal stem cells (BMSCs) display some site-specific properties that differ from those of BMSCs derived from the trunk and appendicular skeleton, but the characteristics of craniofacial BMSCs and the mechanisms that underlie their properties are not completely understood. Previous studies indicated that special AT-rich binding protein 2 (SATB2) may be a potential regulator of craniofacial skeletal patterning and site-specific osteogenic capacity. Here, we investigated the stemness, autophagy, and anti-aging capacity of mandible-derived BMSCs (M-BMSCs) and tibia-derived BMSCs (T-BMSCs) and explored the role of SATB2 in regulating these properties. M-BMSCs not only possessed stronger expression of SATB2 and stemness markers (pluripotency genes, such as Nanog, OCT-4, Sox2, and Nestin) but also exhibited stronger autophagy and anti-aging capacities under normal or hypoxia/serum deprivation conditions compared to T-BMSCs. Exogenous expression of SATB2 in T-BMSCs significantly enhanced the expression of pluripotency genes as well as autophagy and anti-aging capacity. Moreover, SATB2 markedly enhanced osteogenic differentiation of BMSCs in vitro, and promoted bone defect regeneration and the survival of BMSCs that were transplanted into mandibles with critical size defects. Mechanistically, SATB2 upregulates pluripotency genes and autophagy-related genes, which in turn activate the mechanistic target of rapamycin signaling pathway. Collectively, our results provide novel evidence that site-specific BMSCs have distinct biological properties and suggest that SATB2 plays a potential role in regulating the stemness, autophagy, and anti-aging properties of craniofacial BMSCs. The application of SATB2 to manipulate stem cells for the reconstruction of bone defects might represent a new approach. © 2014 Wiley Periodicals, Inc., A Wiley Company.

Background: Acute stroke patients suffering from aspiration may present with acute respiratory distress syndrome (ARDS). There is still a lack of convincing data about the efficacy of corticosteroids in the treatment of aspiration-related ARDS. Therefore, we evaluated the clinical impact of corticosteroids on aspiration-related ARDS. Methods: Between 2012 and 2014, we conducted a retrospective study among acute stroke patients diagnosed with aspiration-related ARDS. The data analyzed included demographic characteristics, clinical manifestations, laboratory examinations, chest imaging, and hospital discharge status. Results: Seventy-three acute stroke patients were diagnosed with aspiration-related ARDS. The hospital mortality rate was 39.7%. Corticosteroids were administered in 47 patients (64.4%). The mean dosage was 1.14 (standard deviation [SD] 0.47) mg/kg daily of methylprednisolone (or an equivalent) by intravenous infusion for a period of 7.3 (SD 3.8) days. Ground glass opacities in chest computed tomography images were resolved when corticosteroids were administered. The admission National Institute of Health Stroke Scale score (odds ratio [OR] 5.17, 95% confidence interval [CI] 1.27-10.64) and Acute Physiology and Chronic Health Evaluation II score (OR 2.00, 95% CI 1.12-3.56) were associated with an increased risk of hospital mortality, while albumin (OR 0.81, 95% CI 0.64-0.92) and corticosteroids therapy (OR 0.50, 95% CI 0.35-0.70) were associated with a decreased risk. Conclusions: Low-dose and short-term corticosteroid therapy may have an impact on survival in aspiration-related ARDS. The presence of ground glass opacities on the chest computed tomography, performed to rule out aspiration-related ARDS, could be translated into an increased possibility of positive response to corticosteroid therapy. © 2016 Zhao et al.

miRNAs (microRNAs) have been validated to play fateful roles in the occurrence and development of cancers by post-transcriptionally targeting 3-untranslated regions of the downstream gene mRNAs to repress mRNA expression. Mounting investigations forcefully document that not only does miR22 biologically impinge on the processes of senescence, energy supply, angiogenesis, EMT (epithelial-mesenchymal transition), proliferation, migration, invasion, metastasis and apoptosis, but also it genetically or epigenetically exerts dual (inhibitory/promoting cancer) effects in various cancers via CNAs (copy number alterations), SNPs (single nucleotide polymorphisms), methylation, acetylation and even more momentously hydroxymethylation. Additionally, miR22 expression may fluctuate with cancer progression in the body fluids of cancer patients and miR22 could amplify its inhibitory or promoting effects through partaking in positive or negative feedback loops and interplaying with many other related miRNAs in the cascade of events, making it possible for miR22 to be a promising and complementary or even independent cancer biomarker in some cancers and engendering profound influences on the early diagnosis, therapeutics, supervising curative effects and prognosis.
