The role of CBL-CIPK signaling in plant responses to biotic and abiotic stresses.

Plants have a variety of regulatory mechanisms to perceive, transduce, and respond to biotic and abiotic stress. One such mechanism is the calcium-sensing CBL-CIPK system responsible for the sensing of specific stressors, such as drought or pathogens. CBLs perceive and bind Calcium (Ca2+) in response to stress and then interact with CIPKs to form an activated complex. This leads to the phosphorylation of downstream targets, including transporters and ion channels, and modulates transcription factor levels and the consequent levels of stress-associated genes. This review describes the mechanisms underlying the response of the CBL-CIPK pathway to biotic and abiotic stresses, including regulating ion transport channels, coordinating plant hormone signal transduction, and pathways related to ROS signaling. Investigation of the function of the CBL-CIPK pathway is important for understanding plant stress tolerance and provides a promising avenue for molecular breeding.

[Outcomes of the second pregnancy after Triple-P procedure in women complicated with placenta accreta spectrum disorders].

Objective: To investigate the safety of the Triple-P procedure in women complicated with severe placenta accreta spectrum disorders (PAS) and its influence on second pregnancy. Methods: From January 2015 to December 2017, the outcomes of the second pregnancy after the Triple-P procedure in 11 pregnant women complicated with PAS in the Third Affiliated Hospital of Guangzhou Medical University and the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. Results: By December 2021, a total of 11 pregnant women who underwent the Triple-P procedure for PAS had a second pregnancy, with a median interval of 3 years (2-3 years). Of the 11 pregnant women, 7 delivered after 36 weeks of gestation. The median gestational age was 38 weeks, and 4 terminated within the first trimester. PAS recurred in 1 of 7 pregnant women (1/7) and was associated with placenta previa. All of the 7 pregnant women were delivered by cesarean section, with a median postpartum blood loss of 300 ml (200-450 ml), and only one pregnant woman required blood transfusion. None of the pregnant women were transferred to the intensive care unit, and there were no uterine rupture, bladder injury, puerperal infection, and neonatal adverse outcomes. Conclusion: Pregnant women who underwent the Triple-P procedure for severe PAS could be considered for second pregnancy with strictly management by an experienced multidisciplinary team, which may result in a good outcome.

[The concept and development direction of elderly oriented food].

Active response to the challenges posed by aging has been established as a national strategy, accompanied by continuous refinement of policies concerning aging work. Decreased digestive system function is commonly present in the natural aging process of older people, which directly affects their food intake, digestion, and absorption, leading to decreased appetite and various forms of malnutrition. It is also a risk factor for age-related diseases such as sarcopenia, osteoporosis, cognitive impairment, and frailty. Nutrition is the foundation for achieving healthy aging. In order to meet the nutritional needs of the elderly population, the Nutrition and Healthy Aging Working Group at the Shanghai Junshi Institute of Life Sciences introduced the concept of "elderly-oriented food" in 2022. In the future, there is an urgent need for comprehensive collaborative efforts to conduct a series of investigations focused on the dietary habits and nutritional requirements of older individuals, in order to evaluate the level of awareness, genuine demands, dietary preferences, and capabilities of selection regarding to the elderly-oriented food. Simultaneously, it is recommended to introduce "Guidelines for the production and application of elderly-oriented food" at the national level to promote the sustainable and orderly development in food industry.

[Leading edge development of food safety].

Food safety in China has been significantly improved since the melamine crisis in 2008 and the promulgation of the first Food Safety Law in 2009. However, food safety is a long standing issue in China due to the backward productive structure of agriculture and food business. In order to further improve the food safety in China, it is critical to reach a consensus on the leading edge concept of food safety and the identification of priority areas based on the concept. The leading edge concept of food safety aims to prevent potential issues and deal with current issues based on the risk, i.e. risk-based approach, as opposed to the concept based on the hazard, i.e. hazard-based approach. Practice is to determine the key problems that need to be solved first according to the concept. This paper expounds the different food safety management strategies and measures caused by the two concepts, and lists several key food safety problems (importance and solutions) determined according to the concept of "risk-based". These examples include foodborne diseases caused by pathogenic microorganisms, antimicrobial resistance, food allergen control, risk assessment of multiple chemical hazards exposure and alternative methods in food toxicology.

[Using the guidelines as a driver to comprehensively promote the physical activity level of Chinese population].

Physical inactivity is responsible for 6% of global deaths, and it is an independent risk factor for cardiovascular diseases, cancer, chronic respiratory diseases and diabetes. The general lack of physical activity has become an important global public health problem. Active and adequate physical activity is an important public health measure to ensure health throughout the life cycle. Under the guidance of the Bureau for Disease Prevention and Control of the National Health Commission, the Chinese Center for Disease Control and Prevention and the Institute of Sports Science of the General Administration of Sport of China jointly organize experts to complete the compilation of The Physical Activity Guidelines for Chinese (2021) based on a large number of domestic and foreign scientific data. We look forward to the release and implementation of the guidelines, which will play an important role in scientifically guiding the physical activity of all types of people in China, reducing the rate of physical inactivity, and promoting the early realization of the goal of the Healthy China Action.

Genetic alterations in primary melanoma in Taiwan.

BACKGROUND: Acral melanoma (AM) is the most common histopathological subtype of malignant melanoma in Asians. However, differences in the mutational profiles underlying AM and nonacral cutaneous melanoma (NAM) in Asians are not well understood. OBJECTIVES: To augment the understanding of the prevalence, patterns and associations of various mutations between different subtypes of melanoma. METHODS: We performed comprehensive genomic profiling of 409 cancer-associated genes, using next-generation sequencing, in 66 primary melanomas comprised of 45 AMs and 21 NAMs. RESULTS: Most of the AMs (n = 27/45; 60%), but only five of 21 (24%) NAMs, were triple wild-type (triple-WT) tumours. Compared with AMs, NAMs exhibited a significantly higher frequency of BRAF mutations. The frequencies of NRAS/KRAS mutations, cell-cycle aberrations, copy number gains in BIRC2, BIRC3 and BIRC5, and gains of receptor tyrosine kinase genes were significantly higher in AMs. Ulceration was found at significantly higher rates in the AMs and NAMs with cell-cycle aberrations and gains of receptor tyrosine kinase genes. Notably, cell-cycle aberrations and copy number gains in BIRC2, BIRC3 and BIRC5 were significantly associated with poor melanoma-specific survival in the 66 patients with melanoma and especially in the 45 patients with AM. Multivariate analysis showed that lymph node metastasis and cell-cycle aberrations were independent prognostic factors of melanoma-specific survival. CONCLUSIONS: This study strengthens our understanding of the patterns and clinical associations of oncogenic mutations in AMs and NAMs in Asians. What's already known about this topic? Mutation frequencies of driver genes vary between melanoma subtypes. Acral melanoma is the most common subtype of melanoma in Asians. KIT mutations and copy number variations occur more frequently in the acral subtype of melanoma than in the nonacral subtype What does this study add? NRAS/KRAS mutations, cell-cycle aberrations, copy number gains in BIRC2, BIRC3 and BIRC5, and amplifications of receptor tyrosine kinase genes were significantly enriched in acral melanoma and could be potential targets for treatment. Melanomas with cell-cycle aberrations and gains in receptor tyrosine kinase genes were significantly more likely to contain ulceration. What is the translational message? Cell-cycle aberrations and copy number gains in BIRC2, BIRC3 and BIRC5 were significantly associated with poor melanoma-specific survival. These observations should be explored further for future drug development.

Colorectal cancer with indeterminate pulmonary nodules.

Colorectal cancer (CRC) is one of the most common malignancies with a dismal prognosis. Indeterminate pulmonary nodules (IPNs) are lung nodules with uncertain nature, generally defined as a noncalcified nodule smaller than 10 mm in diameter or solid nodule no greater than 20 mm at maximum diameter without malignant character. With the widespread use of preoperative staging computed tomography (CT) of the chest and follow-up CT, IPNs are frequently detected in patients with CRC, which makes diagnosis more controversial. Generally, progression to pulmonary metastasis from IPNs is rare. Thus, no further interventions were needed for IPNs in CRC patients. A second reviewing of scans with IPNs by both clinicians and experienced thoracic radiologists may help to obtain a more accurate diagnosis.

[Health management needs standardization].

This article illustrates that health management, as one of the tools of health service, plays an important role in the control and treatment of chronic diseases as well as the history of health management development in China. It was pointed out that currently the concept of health management is not well established in China and the practice of health management in the Chinese market is quite in a mess. Therefore, there is an urgent need for the standardization of health management practice. The China Health Management Association released an organizational standard entitled "Standard for Chronic Disease Health Management" in November, 2019. It is comprehensive, science-based, easy to use and fit into the Chinese situation and it is expected that it will facilitate the development of health management in China.

[COâ and 16S rDNA Sequence Identification of Common Necrophagous Flies in Fujian Province].

ABSTRACT: Objective To identify the species of common necrophagous flies in Fujian Province by gene fragment sequences of mitochondrial cytochrome c oxidase subunit Ⅰ （COⅠ） and 16S ribosomal deoxyribonucleic acid （16S rDNA）, and to explore the identification efficacy of these two molecular markers. Methods In total 22 common necrophagous flies were collected from the death scenes in 9 different regions in Fujian Province and DNA was extracted from the flies after morphological identification. The gene fragments of COⅠ and 16S rDNA were amplified and sequenced. All the sequences were uploaded to GeneBank and BLAST and MEGA 10.0 software were used to perform sequence alignment, homology analysis and intraspecific and interspecific genetic distance analysis. The phylogenetic trees of DNA fragment sequences of COⅠ and 16S rDNA of common necrophagous flies in Fujian Province were established by unweighted pair-group method with arithmetic means （UPGMA）, respectively. Results The flies were classified into 6 species, 5 genera and 3 families by morphological identification. The results of gene sequence analysis showed that the average number of interspecific and intraspecific genetic distance of 16S rDNA ranged from 1.8% to 8.9% and 0.0% to 2.4%, respectively. The average number of interspecific and intraspecific genetic distance of COⅠ ranged from 7.2% to 13.6% and 0.0% to 6.3%, respectively. Conclusion The gene sequences of COⅠ and 16S rDNA can accurately identify the species of different necrophagous flies, and 16S rDNA showed higher value in species identification of common calliphoridae necrophagous flies in Fujian Province.

Routine chest CT for staging of gastric cancer.

BACKGROUND: International guidelines on clinical staging of gastric cancer recommend the use of chest CT for the detection of pulmonary metastases. This study assessed the clinical value of routine chest CT in the staging of gastric cancer. METHODS: This retrospective study included patients identified from the gastric cancer registry of Chang Gung Memorial Hospital, Linkou, Taiwan. All patients who underwent clinical staging between 2008 and 2014 were included. The pattern, site and number of metastases at initial presentation and after surgery with curative intent were evaluated. Pulmonary metastases were defined as multiple small round pulmonary nodules with a random distribution or of variable size. RESULTS: Some 1669 patients were included, of whom 478 (28·6 per cent) had metastatic disease at clinical presentation. The majority of metastases were to the peritoneum (75·7 per cent of patients) or liver (30·5 per cent), and only 27 patients (5·6 per cent) had pulmonary metastases at presentation, none of which were isolated to the lung. Of these 27 patients, 11 had primary lesions located at the cardia/fundus. In 19 patients the lung metastases were also detected on the staging chest X-ray. After surgery there were 196 cancer recurrences. Some 15 patients (7·6 per cent) had lung metastasis and this was not the only site of metastases in any patient. The prevalence of lung metastasis at presentation of the disease and after surgery was 1·6 and 1·5 per cent respectively. CONCLUSION: This study does not support the routine use of chest CT for staging of gastric cancer as isolated pulmonary metastasis in the absence of other metastatic sites could not be detected.

[Clinicopathologic features and prognosis of patients with IgA nephropathy superimposed on transplant glomerulopathy].

Objective: To observe the clinicopathologic features and prognostic of patients with IgA nephropathy (IgAN) superimposed on transplant glomerulopathy (TG+ IgAN). Methods: Electronic medical records of Jinling Hospital were searched for TG+ IgAN patients that was diagnosed during January 2004 to December 2016. Clinicopathologic features and prognoses information were retrieved and analyzed. The primary outcome was initiation of replacement therapy or an eGFR declined to<15 ml·min(-1)·(1.73m(2))(-1). Results: A total of 49 patients with pathologically confirmed TG+ IgAN were enrolled in this study. The median time from renal transplantation to allograft biopsy was 85 months. There were 131 patients with TG in the control group. There was no statistical difference in the age, gender, and immunosuppressive regimen during renal biopsy in the two groups. In TG+ IgAN patients, the median serum creatinine level was 175 µmol/L, the median urinary protein was 1.45 g/24 h, and 16.3% of the patients had nephrotic range proteinuria, the incidence of microscopic hematuria was 40.8%, and the average hemoglobin was 105 g/L. In terms of pathology, the degree of glomerular mesangial matrix hyperplasia in the TG+ IgAN group was significantly heavier compared with TG group (P=0.004), and the degree of hyaline degeneration of the small arteries was lighter (P=0.043). There was no significant difference in interstitial inflammation (i), tubulitis (t), glomerulitis (g), peritubular capillaritis (ptc) and intimal arteritis (v). Calculated by Kaplan-Meier method, the median survival time of 49 patients with TG+ IgAN was 36.9 months, and there was no difference in survival rate of allografts compared with TG group. Conclusions: Compared with TG patients without IgA, TG+ IgAN patients had higher incidence of microscopic hematuria, more severe glomerular mesangial matrix hyperplasia, and no significant differences in other clinicopathological features. The prognosis of TG+ IgAN patients was not significantly different from those without IgAN.

Improvement in lipids after switch to boosted atazanavir or darunavir in children/adolescents with perinatally acquired HIV on older protease inhibitors: results from the Pediatric HIV/AIDS Cohort Study.

OBJECTIVES: Dyslipidaemia is common in perinatally HIV-infected (PHIV) youth receiving protease inhibitors (PIs). Few studies have evaluated longitudinal lipid changes in PHIV youth after switch to newer PIs. METHODS: We compared longitudinal changes in fasting lipids [total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and TC:HDL-C ratio] in PHIV youth enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS) Adolescent Master Protocol (AMP) study who switched to atazanavir/ritonavir (ATV/r)- or darunavir/ritonavir (DRV/r)-based antiretroviral therapy (ART) from an older PI-based ART and those remaining on an older PI. Generalized estimating equation models were fitted to assess the association of a switch to ATV/r- or DRV/r-based ART with the rate of change in lipids, adjusted for potential confounders. RESULTS: From 2007 to 2014, 47 PHIV children/adolescents switched to ATV/r or DRV/r, while 120 remained on an older PI [primarily lopinavir/r (72%) and nelfinavir (24%)]. Baseline age ranged from 7 to 21 years. After adjustment for age, Tanner stage, race/ethnicity, and HIV RNA level, a switch to ATV/r or DRV/r was associated with a more rapid annual rate of decline in the ratio of TC:HDL-C. (ß = -0.12; P = 0.039) than remaining on an older PI. On average, TC declined by 4.57 mg/dL/year (P = 0.057) more in the switch group. A switch to ATV/r or DRV/r was not associated with the rate of HDL-C, LDL-C, or TG change. CONCLUSIONS: A switch to ATV/r or DRV/r may result in more rapid reduction in TC and the TC:HDL-C ratio in PHIV youth, potentially impacting long-term cardiovascular disease risk.

Sunitinib in pancreatic neuroendocrine tumors: updated progression-free survival and final overall survival from a phase III randomized study.

BACKGROUND: In a phase III trial in patients with advanced, well-differentiated, progressive pancreatic neuroendocrine tumors, sunitinib 37.5 mg/day improved investigator-assessed progression-free survival (PFS) versus placebo (11.4 versus 5.5 months; HR, 0.42; P < 0.001). Here, we present PFS using retrospective blinded independent central review (BICR) and final median overall survival (OS), including an assessment highlighting the impact of patient crossover from placebo to sunitinib. PATIENTS AND METHODS: In this randomized, double-blind, placebo-controlled study, cross-sectional imaging from patients was evaluated retrospectively by blinded third-party radiologists using a two-reader, two-time-point lock, followed by a sequential locked-read, batch-mode paradigm. OS was summarized using the Kaplan-Meier method and Cox proportional hazards model. Crossover-adjusted OS effect was derived using rank-preserving structural failure time (RPSFT) analyses. RESULTS: Of 171 randomized patients (sunitinib, n = 86; placebo, n = 85), 160 (94%) had complete scan sets/time points. By BICR, median (95% confidence interval [CI]) PFS was 12.6 (11.1-20.6) months for sunitinib and 5.8 (3.8-7.2) months for placebo (HR, 0.32; 95% CI 0.18-0.55; P = 0.000015). Five years after study closure, median (95% CI) OS was 38.6 (25.6-56.4) months for sunitinib and 29.1 (16.4-36.8) months for placebo (HR, 0.73; 95% CI 0.50-1.06; P = 0.094), with 69% of placebo patients having crossed over to sunitinib. RPSFT analysis confirmed an OS benefit for sunitinib. CONCLUSIONS: BICR confirmed the doubling of PFS with sunitinib compared with placebo. Although the observed median OS improved by nearly 10 months, the effect estimate did not reach statistical significance, potentially due to crossover from placebo to sunitinib. TRIAL REGISTRATION NUMBER: NCT00428597.

Sympathetic Ground State Cooling and Time-Dilation Shifts in an

We report on Raman sideband cooling of ^{25}Mg^{+} to sympathetically cool the secular modes of motion in a ^{25}Mg^{+}-^{27}Al^{+} two-ion pair to near the three-dimensional (3D) ground state. The evolution of the Fock-state distribution during the cooling process is studied using a rate-equation simulation, and various heating sources that limit the efficiency of 3D sideband cooling in our system are discussed. We characterize the residual energy and heating rates of all of the secular modes of motion and estimate a secular motion time-dilation shift of -(1.9±0.1)×10^{-18} for an ^{27}Al^{+} clock at a typical clock probe duration of 150 ms. This is a 50-fold reduction in the secular motion time-dilation shift uncertainty in comparison with previous ^{27}Al^{+} clocks.

Coarse integral holography approach for real 3D color video displays.

A colour holographic display is considered the ultimate apparatus to provide the most natural 3D viewing experience. It encodes a 3D scene as holographic patterns that then are used to reproduce the optical wavefront. The main challenge at present is for the existing technologies to cope with the full information bandwidth required for the computation and display of holographic video. We have developed a dynamic coarse integral holography approach using opto-mechanical scanning, coarse integral optics and a low space-bandwidth-product high-bandwidth spatial light modulator to display dynamic holograms with a large space-bandwidth-product at video rates, combined with an efficient rendering algorithm to reduce the information content. This makes it possible to realise a full-parallax, colour holographic video display with a bandwidth of 10 billion pixels per second, and an adequate image size and viewing angle, as well as all relevant 3D cues. Our approach is scalable and the prototype can achieve even better performance with continuing advances in hardware components.

Supplementation with omega-3 fish oil has no effect on bone mineral density in adults with knee osteoarthritis: a 2-year randomized controlled trial.

UNLABELLED: This study aimed to determine the effect of fish oil on bone mineral density (BMD). There were no differences in the 2-year BMD measures between high and low dose groups after adjusting for baseline BMD. This randomized controlled trial did not demonstrate any efficacy of omega-3 fatty acids on bone loss in adults. INTRODUCTION: The purpose of this study is to investigate whether supplementation with high dose omega-3 fish oil could have an impact on BMD. METHODS: In a multicentre, double-blind randomized controlled trial (RCT) (ACTRN 12607000415404), 202 Australian participants aged ≥40 with knee osteoarthritis (mean age, 61.0 ± 10.0 years; 49 % female) were randomized to receive either high dose (4.5 g eicosapentaenoic acid and docosahexaenoic acid daily) or low dose (0.45 g/day) omega-3 fish oil for 2 years. BMD was assessed at baseline and 2 years by dual energy X-ray absorptiometry. RESULTS: In subjects with baseline and 2-year assessments, mean standardized BMD at baseline for low or high dose group was 1198 ± 198 and 1157 ± 169 mg/cm(2), respectively, for the lumbar spine and was 1035 ± 165 and 1017 ± 174 mg/cm(2), respectively, for the femoral neck. There were no differences in the 2-year BMD measures between high and low dose groups after adjusting for baseline BMD in the complete case regression analyses (lumbar spine 3.7, 95 % confidence interval (CI) -7.9 to 15.3 mg/cm(2) and femoral neck -5.5, 95 % CI -14.9 to 3.9 mg/cm(2)). The findings did not change with additional adjustments of age, gender, study centre and uses of bone-related drugs during the study period as well as using the intention-to-treat analysis or limiting to older participants (≥55 years at the baseline) (all P ≥ 0.25). Mild adverse events such as headache and gastrointestinal intolerance were common but did not occur more frequently in either group. There were no serious adverse events related to the intervention. CONCLUSION: A 2-year supplementation with high-dose omega-3 fish oil did not alter bone loss among men and women with knee osteoarthritis.

Inflammatory bowel disease in pregnancy: a population-based study of prevalence and pregnancy outcomes.

OBJECTIVE: To determine the prevalence of the inflammatory bowel diseases (IBD), ulcerative colitis (UC) and Crohn's disease (CD), in pregnant women and determine pregnancy and fetal/neonatal outcomes. DESIGN: Population-based cohort study. SETTING: New South Wales, Australia, 2001-11. POPULATION: A total of 630 742 women who delivered at ≥20 weeks of gestation. METHODS: Descriptive and multivariate regression analyses of perinatal data linked to hospital admission data. We compared birth outcomes of women with and without a documented diagnosis of IBD. MAIN OUTCOME MEASURES: Caesarean section, severe maternal morbidity, preterm birth <37 weeks of gestation, planned preterm birth, small-for-gestational-age (birthweight <10th centile), perinatal mortality (stillbirth/neonatal death ≤28 days). RESULTS: In all, 1960 women (0.31%) with IBD, who had 2781 births (1183 UC, 1287 CD and 311 IBD-indeterminate). Women with IBD were more likely than women without IBD to have a caesarean section [41.5 versus 28.2%, adjusted risk ratio (aRR) 1.38, 95% CI 1.31-1.45], severe maternal morbidity (2.6 versus 1.6%, aRR 1.54, 95% CI 1.17-2.03), preterm birth (9.7 versus 6.6%, aRR 1.47, 95% CI 1.30-1.66), planned preterm birth (5.3 versus 2.9%, aRR 1.74, 95% CI 1.47-2.07), and their infants to be small-for-gestational-age (9.7 versus 9.5%, aRR 1.19, 95% CI 1.04-1.36). There was no evidence of a difference in perinatal mortality. CONCLUSION: Pregnancy-associated IBD is more common than previously reported. Pregnancies complicated by IBD at or near the time of birth have significantly higher rates of adverse pregnancy outcomes than pregnancies of women without IBD. TWEETABLE ABSTRACT: Increased rates preterm birth and caesarean section in women with inflammatory bowel disease.

H19 serves as a diagnostic biomarker and up-regulation of H19 expression contributes to poor prognosis in patients with gastric cancer.

Emerging evidences indicate that dysregulated long noncoding RNAs (lncRNAs) are implicated in cancer tumorigenesis and progression and might be used as diagnosis and prognosis biomarker, or potential therapeutic targets. LncRNA H19 has been reported to be upregulated in diverse human cancers; however, its clinical significance in gastric cancer (GC) remains elusive. Expression levels of H19 in 128 pairs of GC and adjacent normal tissues, GC cell lines and GC juices compared to their corresponding controls were detected by real-time quantitative polymerase chain reaction (qPCR) assay. A receiver operating characteristic (ROC) curve and Kaplan-Meier analysis were constructed to evaluate the diagnostic and prognostic values. Univariate and multivariate analysis were performed using the Cox proportional hazard analysis. H19 expression was remarkably increased in GC tissues and cell lines compared with that in the normal control, and its up-regulation was significantly correlated to invasion depth (P < 0.001), advanced TNM stage (P = 0.002) and regional lymph nodes metastasis (P < 0.001) in GC. H19 levels were robust in differentiating GC tissues from controls [area under the curve (AUC) = 0.697; 95% confidence interval (CI) = 0.636-0.752, p<0.01]. Kaplan-Meier analysis demonstrated that increased H19 expression contributed to poor overall survival (P = 0.017) and disease-free survival (P = 0.024) of patients. A multivariate survival analysis also indicated that H19 could be an independent prognostic marker. The levels of H19 in gastric juice from gastric patients were significantly higher than those from normal subjects (P = 0.034). Furthermore, knockdown of H19 expression by siRNA could inhibit cell migration and invasion in GC cells partly via regulating E-cadherin protein expression. H19 might serve as a promising biomarker for early detection and prognosis prediction of GC.
