SQ3370 Activates Cytotoxic Drug via Click Chemistry at Tumor and Elicits Sustained Responses in Injected & Non-injected Lesions

While systemic immuno-oncology therapies have shown remarkable success, only a limited subset of patients benefit from them. Our Click Activated Protodrugs Against Cancer (CAPAC™) Platform is a click chemistry-based approach that activates cancer drugs at a specific tumor with minimal systemic toxicity. CAPAC Platform is agnostic to tumor characteristics that can vary across patients and hence applicable to several types of tumors. We describe the benefits of SQ3370 (lead candidate of CAPAC) to achieve systemic anti-tumor responses in mice bearing two tumors. SQ3370 consists of a biopolymer, injected in a single lesion, followed by systemic doses of an attenuated protodrug™ of doxorubicin (Dox). SQ3370 was well-tolerated at 5.9-times the maximum dose of conventional Dox, increased survival by 63% and induced a systemic anti-tumor response against injected and non-injected lesions. The sustained anti-tumor response also correlated with immune activation measured at both lesions. SQ3370 could potentially benefit patients with micro-metastatic lesions.

Comparative Study of Oral Bacteria and Fungi Microbiota in Tibetan and Chinese Han Living at Different Altitude

Knowledge about the impact of altitude and ethnicity on human oral microbiota is currently limited. To obtain the baseline of normal salivary microbiota, we analyzed the bacteria and fungi composition in Tibetan (HY group) and Han population (CD group) living at different altitudes by using next-generation sequencing (NGS) technology combined with PICRUSt and FUNGuild analyses. There were significant differences in oral microbiota composition between the two groups at phylum and genus levels. At the phylum level, the HY group had higher relative abundances of Firmicutes and Ascomycota, whereas the Bacteroidetes and Basidiomycota in the CD group were richer. These changes at the phylum level reflected different dominant genus compositions. Compared with the Han population, Candida, Fusarium, Zopfiella, Streptococcus, Veillonella and Rothia in Tibetan were higher. Surprisingly, the Zopfiella was found almost exclusively in the Tibetan. The PICRUSt and FUNGuild analysis also indicated that the function of the bacterial and fungal communities was altered between the two groups. In conclusion, our results suggest that there are significant differences in oral microbial structure and metabolic characteristics and trophic modes among Tibetan and Han population living at different altitudes. We first established the oral microbiota framework and represented a critical step for determining the diversity of oral microbiota in the Tibetan and Han population.

Long noncoding RNA NEAT1 promotes the growth of gastric cancer cells by regulating miR-497-5p/PIK3R1 axis

OBJECTIVE

To investigate the molecular mechanisms of long noncoding RNA (lncRNA) nuclear paraspeckle assembly transcript 1 (NEAT1) in gastric cancer (GC) development progress.

MATERIALS AND METHODS

Relative mRNA and protein expression levels were quantified by quantitative Reverse Transcription-PCR (qRT-PCR) or Western blot analysis. Cell proliferation and cell apoptosis were measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay and flow cytometry, respectively. Binding sites of miR-497-5p on NEAT1 or phosphoinositide-3-kinase regulatory subunit 1 (PIK3R1) were determined by RNA pull-down assay or dual-luciferase reporter assay. Finally, the tumorigenic role of NEAT1 in GC was assessed using a xenograft model on nude mice.

RESULTS

NEAT1 was upregulated in GC tissues, promoted proliferation, and inhibited apoptosis of GC cells. NEAT1 could directly bind to and negatively regulate miR-497-5p expression. PIK3R1 was then identified as a downstream target of miR-497-5P. In GC cell models, PIK3R1 was found to be directly negatively regulated by miR-497-5p and indirectly positively regulated by NEAT1. Finally, NEAT1 knockdown inhibited tumor growth, increased miR-497-5p expression, and decreased PIK3R1 expression in xenograft model mice compared with the negative control.

CONCLUSIONS

Functioned as an oncogene, NEAT1 promoted cell growth in GC by regulating miR-497-5p/PIK3R1 axis. These results provided valuable insights into the underlying regulation signaling in gastric cancer development, shedding light on NEAT1 a promising therapeutic target from bench to clinic.

An Asymptomatic SARS-CoV-2-Infected Infant With Persistent Fecal Viral RNA Shedding in a Family Cluster: A Rare Case Report

An outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become pandemic worldwide. A better understanding of asymptomatic infections is crucial to prevent and control this epidemic. Here, we report the epidemiological and clinical characteristics of a family cluster with SARS-CoV-2 infection. In the family cluster, a 32-year-old male (case 1) and a 53-year-old female (case 2, the mother-in-law of case 1) exhibited clinical symptoms of COVID-19, while case 1's 32-year-old wife (case 3) and their 11-month-old daughter (case 4) were both asymptomatic. Notably, case 4's nasopharyngeal swab samples was negative for nearly 80 days, and her immune system has been boosted for at least 57 days, but the fecal samples have tested positive for 100 days (May 13, 2020), suggesting SARS-CoV-2 may invade enterocytes and may exist in individuals with low antiviral immunity for a long term. This report highlights that asymptomatic infections should be managed with caution and vigilance. For SARS-CoV-2 testing of asymptomatic cases, besides the normally used nasopharyngeal swab, fecal sample testing is also needed.

Tailoring phase transformation strengthening and plasticity of nanostructured high entropy alloys

Metastable high entropy alloys (HEAs) have attracted extensive attention due to their excellent combination of high strength and great plasticity. In this work, we utilize constraining effects to tailor phase transformation strengthening and plasticity of nanostructured HEA ([double bond, length as m-dash]FeCoCrNi) thin films prepared by the magnetron sputtering technique via HEA/Cu and HEA/Ni nanotwinned nanolaminates (NTNLs). It is uncovered that the HEA/Cu NTNLs without phase transformation exhibit the fashion of "smaller is stronger" and HEA layers become more favorable to detwin at a smaller layer thickness (h). By contrast, the HEA/Ni NTNLs manifest an ultra-high peak hardness plateau accompanied by the FCC-to-HCP phase transformation in HEA layers at large h≥ 25 nm, whereas they manifest size-dependent hardness when detwinning occurs at smaller h. This unusual plastic deformation behavior of HEA/X (X = Cu, Ni) NTNLs was rationalized by partial-based mechanisms. These findings open a new avenue to achieve superior mechanical properties of HEAs particularly at the nanoscale.

Latest observations of total gaseous mercury in a megacity (Lanzhou) in northwest China

One year of online total gaseous mercury (TGM) measurements were carried out for the first time in Lanzhou, a city in northwest China that was once seriously polluted. Measurements were made from October 2016 to October 2017 using the Tekran 2537B instrument, and the annual mean concentration of TGM in Lanzhou was 4.48 ± 2.32 ng m^-3 (mean ± standard deviation). TGM concentrations decreased during the measurement period, with autumn 2017 average concentrations 2.87 ng m^-3 lower than autumn 2016 average concentrations. Similar diurnal variations of TGM were obtained in different seasons with low concentrations observed in the afternoon and high concentrations at night. The principal component analysis and conditional probability function results revealed that the sources of mercury were similar to the other atmospheric pollutants such as SO₂, CO, NO₂ and PM_2.5, and were mainly from industrial combustion plants in urban districts. Concentration weighted trajectory analysis using backward trajectories demonstrated that higher mercury concentrations were related to air masses from adjacent regions, indicating the importance of influences from local-to-regional scale sources. A synthesis of multi-decadal atmospheric mercury measurements in Lanzhou and other Chinese megacities revealed that atmospheric mercury concentrations were either generally stable or experienced a slight decrease, during a time when China implemented control measures on atmospheric pollution. Long-term atmospheric mercury observations in urban and background sites in China are warranted to assess mercury pollution and the effectiveness of China's mercury control policies.

[Comparison of short-term and long-term efficacy between robot-assisted and thoracoscopy-laparoscopy-assisted radical esophageal cancer surgery]

Objective: To explore the safety and short-term and long-term efficacy of robot-assisted radical esophageal cancer surgery. Methods: A prospective randomized controlled trial was conducted. Patients who were preoperatively diagnosed as stage 0-IIIB esophageal squamous cell carcinoma and suitable for minimally invasive surgery in our hospital from January 1, 2014 to June 30, 2018 were prospectively enrolled. Those of age ≥75 years having received preoperative neoadjuvant therapy, contradicted to anesthesia or operation due to severe complications, with history of thoracotomy or laparotomy, with concurrent malignant tumors, without complete informations or refusing to participate in this study were excluded. Participants were randomly divided into the thoracoscopy-laparoscopy group and the robot group using a random number table in ratio of 1:1. Preoperative clinicopathological data, surgical data and postoperative outcomes were recorded. The patients were followed up mainly by telephone. Follow-up endpoint was recurrence of esophageal cancer and death. Kaplan-Meier method was used to estimate survival rate. The survival difference between the two groups was analyzed using the log-rank test. Results: According to above criteria, a total of 192 esophageal cancer patients were enrolled finally, including 144 males and 48 females with mean age of (61.9±8.6) years. The robot group had 94 cases, including 72 males and 22 females with mean age of (61.3±8.2) years, and the thoracoscopy-laparoscopy group had 98 cases, including 72 males and 26 females with mean age of (62.4±9.1) years. There were no significant differences in baseline data between the two groups (all P>0.05). Operation was abandoned in one case in each group due to extensive pleural cavity metastasis and one case in each group was converted to thoracotomy. The success rate of operation was 97.9% (92/94) in the robot group and 98.0% (96/98) in the thoracoscopy-laparoscopy group (χ(2)=0.002, P=0.996). The number of lymph nodes dissected in the robot group was significantly higher than that in the thoracoscopy-laparoscopy group (29.2±12.5 vs. 22.8±13.3, t=3.433, P=0.001), while there were no significant differences in operative time, intraoperative blood loss, R0 resection rate, postoperative 30-day mortality, postoperative hospital stay, ICU stay, time to withdrawal of chest drainage tube, ICU readmission, and postoperative morbidity of complications between the two groups (all P>0.05). The median follow-up time was 21 (3 to 57) months. During the follow-up, 3 cases and 4 cases were lost, and 2 cases and 3 cases died of other diseases in the robot group and in the thoracoscopy-laparoscopy group respectively. Recurrence occurred in 39 cases during follow-up, including 14 recurrences in the robotic group with 1- and 3-year recurrence-free survival rates of 92.4% and 87.6% respectively and the median recurrence time of 15 (9 to 42) months. There were 25 recurrences in the thoracoscopy-laparoscopy group with 1- and 3-year recurrence-free survival rates of 81.7% and 67.9% respectively and the median recurrence time of 9 (3 to 42) months. There was significant difference in recurrence-free survival between the two groups (χ(2)=4.193, P=0.041). Conclusions: The robotic surgical system has good oncology effect and surgical safety in the radical operation of esophageal cancer, which deserves further research and promotion.

[Relationship of body mass index, waist circumference and waist-to-hip ratio with diabetes mellitus in community residents aged 15 years old and above in Pudong new district, Shanghai]

Objective: To analyze the relationship of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) with diabetes mellitus in community residents aged ≥15 years in Pudong new district of Shanghai, and provide evidence for the prevention and treatment of diabetes mellitus. Methods: Using multi-stage stratified cluster sampling method, a total of 7 194 community residents aged ≥15 years were surveyed by using questionnaire, physical examination and laboratory tests in 2016. The relationship of BMI, waist circumference and waist-hip ratio with diabetes mellitus was analyzed by χ(2) test, single factor linear correlation and logistic regression analyses. Results: In 2016, the crude prevalence rate of diabetes mellitus in Pudong was 27.37%, which was 12.75% after standardization. The prevalence rate of diabetes mellitus was slightly higher in men than in women and was increased with age. The levels of FPG, 2 h plasma glucose and HbA1c were positively correlated with BMI, WC and WHR. After adjusting the confounding factors, multiple logistic regression analysis showed that obesity (OR=1.351, P<0.01), excessive waist circumference (OR=1.255, P<0.01) and high WHR (OR=1.291, P<0.01) were risk factors for diabetes mellitus. Conclusions: The increase of obesity, WC and WHR will increase the risk for diabetes mellitus. It is important to maintain healthy weight, especially the control of WC and WHR, reduce the accumulation of abdominal fat to reduce the risk for diabetes mellitus.

[Study on the effects of noise on hypertension and hyperglycemia among occupational workers]

Objective: To study the effect of noise on hypertension and hyperglycemia among occupational workers. Methods: Total 670 workers in an automobile manufacturing company were selected as the subjects of physical examination in 2017. According to the noise exposure or not, the subjects were divided into control group (no noise exposure) 143 and contact group (noise exposure) 527. Questionnaire survey and physical examination were conducted. The measurement data were analyzed by t-test, and the count data and grade data were analyzed by χ(2) test. The influence of noise on blood glucose, heart rate, blood pressure and other indicators was analyzed by logistic regression, and the OR and 95%CI of each risk factor were calculated. Results: The average age of the control group and the contact group was no significant difference (P>0.05) . There were 139 (20.7%) cases of high systolic pressure, 154 (23.0%) cases of high diastolic pressure, 63 (9.4%) cases of hyperglycemia, 29 (4.3%) cases of tachycardia. Compared with the control group, there were significant differences in systolic blood pressure, diastolic blood pressure and blood glucose in the contact group (P<0.05) . Compared with the control group, the systolic blood pressure, diastolic blood pressure and blood glucose of the subjects in the corresponding age contact group increased significantly (P<0.05) . The years of noise exposure were protective factors for systolic and diastolic blood pressure (OR=0.970, 0.973) . Conclusion: Noise exposure may increase blood pressure and blood sugar of occupational workers, but the effect on heart rate can not be determined.

The efficacy and safety of immunotherapy targeting the PD-1 pathway for advanced urothelial carcinoma: a meta-analysis of published clinical trials

INTRODUCTION

Urothelial carcinoma (UC) is an aggressive malignancy and has a poor prognosis in the metastatic state. Treatment of UC remains a challenge, and as a first-line regimen for advanced UC, standard platinum-based chemotherapy is unfit for many patients due to numerous comorbidities and poor performance status. Recently, five immune checkpoint inhibitors have been approved for the treatment of patients with advanced UC who were ineligible for platinum-based regimens or suffered tumor progression in post-platinum setting. However, not long ago, the U.S. Food and Drug Administration restricted the use of two common immune checkpoint blockades, atezolizumab and pembrolizumab, due to uncertain survival benefit as mono-therapy. In this scenario, we reviewed rapidly surfacing clinical trials to assess the efficacy and safety of immunotherapy targeting the PD-1 pathway for advanced UC.

METHODS

A comprehensive search was conducted in PubMed, EMBASE and Cochrane Library for all clinical trials where the efficacy and safety were reported. Our primary outcome was efficacy evaluated by objective response rate (ORR), 1-year overall survival (OS) rate and 1-year progression-free survival (PFS) rate, and second outcome was safety assessed by any grade and grade 3-4 treatment-related adverse events (TRAEs). We chose percentages with 95% confidence intervals (CI) as the evaluation indexes and used a random-effects model to account for heterogeneity.

RESULTS

We included 14 clinical trials with 2674 total patients in this meta-analysis. After removing unqualified studies on the basis of sensitivity analyses, 13 studies were pooled to evaluate the overall ORR, 8 studies for the 1-year OS rate and 6 studies for the 1-year PFS rate. The pooled data of ORR, 1-year OS rate, and 1-year PFS rate were 0.20 (95% CI 0.18-0.22, I² = 38.4%, P = 0.078), 0.50 (95% CI 0.46-0.53, I² = 30.3%, P = 0.186), and 0.17 (95% CI 0.14-0.20, I² = 0.0%, P = 0.668), respectively. Similarly, 13 trials were utilized to compute the pooled rate of any-grade TRAEs. The pooled estimation of any-grade was 0.65 (95% CI 0.63-0.67, I² = 1.7%, P = 0.429). The pooled rate of grade 3-4 TRAEs subgroups with Atezolizumab, Pembrolizumab, Durvalumab, Nivolumab and Avelumab were 0.11 (95% CI 0.06-0.15, I² = 83.5%, P = 0.000), 0.15 (95% CI 0.13-0.18, I² = 0.0%, P = 0.971), 0.06 (95% CI 0.03-0.09, I² = 0.0%, P = 0.566), 0.19 (95% CI 0.15-0.23, I² = 0.0%, P = 0.480) and 0.08 (95% CI 0.05-0.11, I² = 0.0%, P = 0.702), respectively.

CONCLUSION

This study showed that the immunotherapy targeting the PD-1 pathway had durable efficacy and acceptable safety in patients with advanced UC. The comprehensive role of immune checkpoint inhibitors in comparison to other treatments needs further confirmation basing on RCTs.

Reduced E-cadherin expression as a prognostic factor in non-muscle-invasive bladder cancer: A systematic review and meta-analysis

INTRODUCTION AND OBJECTIVES

The exact role of E-cadherin in non-muscle-invasive bladder cancer (NMIBC) is still unknown, and the aims of this study were to prove whether reduced E-cadherin expression can be a prognostic factor in patients with NMIBC.

MATERIALS AND METHODS

A meta-analysis was conducted to assess the prognostic value of reduced E-cadherin expression in NMIBC. The PubMed, Embase and Web of Science databases were included in the study search.

RESULTS

Fifteen studies with a total of 1538 NMIBC patients were included. The results showed that reduced E-cadherin expression was significantly associated with poor recurrence-free survival (RFS) (pooled HR 2.16, 95% CI 1.22-3.85) and progression-free survival (PFS) (pooled HR 1.91, 95% CI 1.52-2.40) in NMIBC patients.

CONCLUSION

E-cadherin can be a prognostic factor for patients with NMIBC.

Immediate early response protein 2 promotes the migration and invasion of hepatocellular carcinoma cells via regulating the activity of Rho GTPases

Human immediate early response 2 (IER2) has been implicated in tumor cell motility and metastasis; however, the underlying mechanisms in hepatocellular carcinoma (HCC) metastasis remain to be clarified. In this study, we demonstrate that dysregulation of IER2 was shown in HCC clinical samples, and IER2 expression resulted in the promotion of cell migration and invasion in vitro, and HCC tumor growth and pulmonary metastasis in vivo. Moreover, we showed that IER2 expression altered assembly of the actin cytoskeleton rearrangement. Furthermore, MAPK and PI3K/Akt signaling pathways induced by IER2 were confirmed to be probably involved in regulating the activity of Rho GTPases, such as RhoA, Rac1 and Cdc42. Collectively, our results indicated a significant role of IER2 in the HCC cell motility and metastasis through MAPK and PI3K/Akt signaling pathways to regulate the activity of Rho GTPases, thereby modulating actin cytoskeleton rearrangement, unveiling a novel mechanism of cell motility regulation induced by IER2.

Measures of body fatness and height in early and mid-to-late adulthood and prostate cancer: risk and mortality in The Pooling Project of Prospective Studies of Diet and Cancer

BACKGROUND

Advanced prostate cancer etiology is poorly understood. Few studies have examined associations of anthropometric factors (e.g. early adulthood obesity) with advanced prostate cancer risk.

PATIENTS AND METHODS

We carried out pooled analyses to examine associations between body fatness, height, and prostate cancer risk. Among 830 772 men, 51 734 incident prostate cancer cases were identified, including 4762 advanced (T4/N1/M1 or prostate cancer deaths) cases, 2915 advanced restricted (same as advanced, but excluding localized cancers that resulted in death) cases, 9489 high-grade cases, and 3027 prostate cancer deaths. Cox proportional hazards models were used to calculate study-specific hazard ratios (HR) and 95% confidence intervals (CI); results were pooled using random effects models.

RESULTS

No statistically significant associations were observed for body mass index (BMI) in early adulthood for advanced, advanced restricted, and high-grade prostate cancer, and prostate cancer mortality. Positive associations were shown for BMI at baseline with advanced prostate cancer (HR = 1.30, 95% CI = 0.95-1.78) and prostate cancer mortality (HR = 1.52, 95% CI = 1.12-2.07) comparing BMI ≥35.0 kg/m2 with 21-22.9 kg/m2. When considering early adulthood and baseline BMI together, a 27% higher prostate cancer mortality risk (95% CI = 9% to 49%) was observed for men with BMI <25.0 kg/m2 in early adulthood and BMI ≥30.0 kg/m2 at baseline compared with BMI <25.0 kg/m2 in early adulthood and BMI <30.0 kg/m2 at baseline. Baseline waist circumference, comparing ≥110 cm with <90 cm, and waist-to-hip ratio, comparing ≥1.00 with <0.90, were associated with significant 14%-16% increases in high-grade prostate cancer risk and suggestive or significant 20%-39% increases in prostate cancer mortality risk. Height was associated with suggestive or significant 33%-56% risks of advanced or advanced restricted prostate cancer and prostate cancer mortality, comparing ≥1.90 m with <1.65 m.

CONCLUSION

Our findings suggest that height and total and central adiposity in mid-to-later adulthood, but not early adulthood adiposity, are associated with risk of advanced forms of prostate cancer. Thus, maintenance of healthy weight may help prevent advanced prostate cancer.

Analysis of first-episode and chronic schizophrenia using multi-modal magnetic resonance imaging

OBJECTIVE

The brain structure and function differences among first-episode schizophrenia (FESZ) patients, chronic schizophrenia (CSZ) patients, and normal control (NC) subjects were investigated using structural and functional magnetic resonance imaging (MRI). Also, a support vector machine (SVM) combined with recursive feature elimination (RFE) was used for classification.

PATIENTS AND METHODS

First, 44 FESZ patients, 44 CSZ patients, and 56 NC subjects were recruited, and structural MRI images were acquired. The regional gray matter volumes (GMVs) of 90 regions of interest (ROIs) were calculated, two-sample t-tests were conducted to analyze the GMV differences among the groups, and the partial correlations between the Positive and Negative Syndrome Scale (PANSS) scores and altered regional GMVs were calculated. Individual functional MRI images of the three groups were measured. The individual regional homogeneity (ReHo), amplitude of low-frequency fluctuations (ALFF), and degree of centrality (DC) values of the 90 ROIs were calculated and used to evaluate the differences among the groups. Then, the partial correlations between the PANSS scores and altered regional ReHo, ALFF, and DC were determined. An SVM combined with RFE was employed for classification using both structural and functional MRI input features. The sensitivity and specificity were measured to quantify the SVM performance.

RESULTS

The GMVs in the bilateral calcarine of FESZ and CSZ patients were significantly lower than that of NC subjects. Compared to the NC group, the GMV was significantly reduced in numerous additional brain regions of the CSZ group. In comparison to the NC group, the patient groups exhibited significant ReHo increases in several regions and ReHo reductions in the occipital lobe. ReHo in the insula and left postcentral gyrus of CSZ patients were significantly lower than that of the NC subjects. Compared with the NC group, both patient groups exhibited ALFF aberrances in numerous regions. A significant reduction of ReHo, ALFF, and DC in certain regions were also found in patient groups compared with that of NC group. Significant positive correlations were found between the PANSS scores and ReHo and ALFF of the temporal and frontal lobes, while these correlations were negative in the occipital lobe. The SVM with RFE achieved excellent classification performance. The best performance was obtained using the following inputs: the ReHo and ALFF for FESZ/NC classification; the DC, ReHo, and ALFF for FESZ/CSZ classification; and the ReHo and ALFF for CSZ/NC classification.

CONCLUSIONS

Our data indicate that compared with the FESZ patients, brain GMV aberrances was increased in the CSZ patients. The functional features including DC, ReHo, and ALFF, could facilitate FESZ diagnosis, which is more sensitive than structural features in classification. The SVM with RFE presents excellent classification performance and assists SZ diagnosis.

Integrated microRNA and proteome analysis reveal a regulatory module in hepatic lipid metabolism disorders in mice with subclinical hypothyroidism

Subclinical hypothyroidism (SCH) is becoming a global health problem due to its increasing prevalence and potential adverse effects, including cardiovascular diseases and nonalcoholic fatty liver disease (NAFLD). However, the association between SCH and NAFLD remains controversial. MicroRNAs (miRNAs/miRs) have been reported to be implicated in lipid metabolism disorders; however, how miRNAs regulate hepatic lipid metabolism in SCH mice remains unknown. The present study investigated miRNA alterations and proteome profiles in an SCH mouse model, which was generated by methimazole administration in mice for 16 weeks. Next, the profiles of 17 miRNAs that are critical to hepatic lipid metabolism and the proteome were investigated using reverse transcription-quantitative polymerase chain reaction and iTRAQ labeling in the liver specimens of SCH (n=9) and control (n=7) mice. Putative target prediction of miRNAs was also conducted using TargetScan and miRanda. Compared with the control mice, SCH mice had 8 miRNAs and 36 proteins with significantly different expression in the liver tissues. Furthermore, a regulatory module containing 3 miRNAs (miR-34a-5p, miR-24-3p and miR-130a-3p) and 4 proteins (thioredoxin, selenium-binding protein 2, elongation factor 1β and prosaposin) was identified. Overall, integrated analysis of miRNAs and the proteome highlighted a regulatory module between miRNAs and proteins, which, to a certain extent, may contribute to a better understanding of hepatic lipid metabolism disorders in SCH mice.
