FoxO induces pupal diapause by decreasing TGFß signaling.

Diapause is a form of dormancy used widely by insects to survive adverse seasons. Previous studies have demonstrated that forkhead box O (FoxO) is activated during pupal diapause initiation in the moth Helicoverpa armigera. However, it is unclear how FoxO induces diapause. Here, we show that knockout of FoxO causes H. armigera diapause-destined pupae to channel into nondiapause, indicating that FoxO is a master regulator that induces insect diapause. FoxO activates the ubiquitin-proteasome system (UPS) by promoting ubiquitin c (Ubc) expression via directly binding to the Ubc promoter. Activated UPS decreases transforming growth factor beta (TGFß) receptor signaling via ubiquitination to block developmental signaling to induce diapause. This study significantly advances the understanding of insect diapause by uncovering the detailed molecular mechanism of FoxO.

Activation of protein arginine methyltransferase 1 and subsequent extension of moth lifespan is effected by the ROS/JNK/CREB signaling axis.

Previous studies have demonstrated that high physiological levels of reactive oxygen species induce pupal diapause and extend lifespan in the moth Helicoverpa armigera. This has been shown to occur via protein arginine methyltransferase 1 (PRMT1) blockade of Akt-mediated phosphorylation of the transcription factor FoxO, after which activated FoxO promotes the initiation of diapause. However, it is unclear how PRMT1 is activated upstream of FoxO activity. Here, we show that high reactive oxygen species levels in the brains of H. armigera diapause-destined pupae activate the expression of c-Jun N-terminal kinase, which subsequently activates the transcription factor cAMP-response element binding protein. We show that cAMP-response element binding protein then directly binds to the PRMT1 promoter and upregulates its expression to prevent Akt-mediated FoxO phosphorylation and downstream FoxO nuclear localization. This novel finding that c-Jun N-terminal kinase promotes FoxO nuclear localization in a PRMT1-dependent manner to regulate pupal diapause reveals a complex regulatory mechanism in extending the healthspan of H. armigera.

Reactive oxygen species extend insect life span using components of the insulin-signaling pathway.

Reactive oxygen species (ROS) are well-known accelerants of aging, but, paradoxically, we show that physiological levels of ROS extend life span in pupae of the moth Helicoverpa armigera, resulting in the dormant state of diapause. This developmental switch appears to operate through a variant of the conventional insulin-signaling pathway, as evidenced by the facts that Akt, p-Akt, and PRMT1 are elevated by ROS, but not insulin, and that high levels of p-Akt fail to phosphorylate FoxO through PRMT1-mediated methylation. These results suggest a distinct signaling pathway culminating in the elevation of FoxO, which in turn promotes the extension of life span characteristic of diapause.

TGF-ß and BMP signals regulate insect diapause through Smad1-POU-TFAM pathway.

The transforming growth factor-ß (TGF-ß) superfamily signaling pathway contains two general branches, known as TGF-ß and bone morphogenetic protein (BMP), that regulate development in animals. It is well known that TGF-ß superfamily signaling participates in the regulation of dauer (lifespan extension) in Caenorhabditis elegans, but little is known about the molecular mechanisms of lifespan extension in the pathway. Diapause, a programmed developmental arrest in insects, is similar to dauer in C. elegans. In this study, we find that TGF-ß superfamily signaling regulates Helicoverpa armigera diapause via a novel mechanism. Both TGF-ß and BMP signals are weaker in the brains of diapause-destined pupae than in nondiapause-destined pupae, and the levels of p-Smad1, POU, TFAM, and mitochondrial activity are decreased in diapause pupae. Development in nondiapause pupae is delayed by an injection of TGF-ß or BMP receptor inhibitors. Both TGF-ß and BMP signals can activate a common target, Smad1. ChIP and EMSA assays indicate that Smad1 can bind to the POU promoter to regulate its expression. POU can improve the transcription of TFAM, which regulates mitochondrial activity. This is the first report showing that both TGF-ß and BMP signals regulate development or diapause through the Smad1-POU-TFAM-mitochondrial activity in insects.

Targeting of SPP1 by microRNA-340 inhibits gastric cancer cell epithelial-mesenchymal transition through inhibition of the PI3K/AKT signaling pathway.

Gastric cancer (GC) is a common heterogeneous disease. The critical roles of microRNA-340 (miR-340) in the development and progression of GC were emphasized in accumulating studies. This study aims to examine the regulatory mechanism of miR-340 in GC cellular processes. Initially, microarray technology was used to identify differentially expressed genes and regulatory miRs in GC. After that, the potential role of miR-340 in GC was determined via ectopic expression, depletion, and reporter assay experiments. Expression of secreted phosphoprotein 1 (SPP1), miR-340, phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) pathway, and epithelial-mesenchymal transition (EMT)-related genes was measured. Moreover, to further explore the function of miR-340 in vivo and in vitro, proliferation, apoptosis, migration, invasion, and tumorigenic capacity were evaluated. SPP1 was a target gene of miR-340 which could then mediate the PI3K/AKT signaling pathway by targeting SPP1 in GC. Furthermore, miR-340 levels were reduced and SPP1 was enriched in GC tissues and cells, with the PI3K/AKT signaling pathway being activated. Inhibitory effects of upregulated miR-340 on SPP1 and the PI3K/AKT signaling pathway were confirmed in vivo and in vitro. Overexpression of miR-340 or the silencing of SPP1 inhibited GC cell proliferation, invasion, migration, and EMT process, but promoted apoptosis of GC cells. Typically, targeting of SPP1 by miR-340 may contribute to the inhibition of proliferation, migration, invasion, and EMT of GC cells via suppression of PI3K/AKT signaling pathway.

HIF-1 regulates insect lifespan extension by inhibiting c-Myc-TFAM signaling and mitochondrial biogenesis.

Diapause (developmental arrest) is characterized by dramatic depression of metabolic activity and profoundly extends insect lifespan, similar to the Caenorhabditis elegans dauer stage and Drosophila longevity; however, the molecular mechanism of low metabolism in insect diapause is unclear. Here, we show that HIF-1α expression is significantly increased in diapause-destined pupal brains compared to nondiapause-destined pupal brains and that HIF-1α negatively regulates mitochondrial biogenesis. HIF-1α mediates this effect by inhibiting c-Myc activity via proteasome-dependent degradation of c-Myc. The mitochondrial transcription factor A (TFAM), which encodes a key factor involved in mitochondrial transcription and mitochondrial DNA replication, is activated by the binding of c-Myc to the TFAM promoter, thereby inducing transcription. Loss of TFAM expression is a major factor contributing to reducing the mitochondrial activity. Thus, the HIF-1α-c-Myc-TFAM signaling pathway participates in the regulation of mitochondrial activity for insect diapause or lifespan extension.

Assessment of the Link between XRCC1 Arg399Gln Polymorphism and Breast Cancer: a Meta-Analysis in a Single Ethnic Group.

BACKGROUND: Although various individual studies have been conducted to determine the association between X-ray repair cross-complementing group 1 (XRCC1) Arg399Gln polymorphism and breast cancer, the results remain inconclusive. To assess the influence of XRCC1 Arg399Gln polymorphism on the risk of breast cancer, a metaanalysis was performed in a single ethnic group. METHODS: Eligible studies were identified via databases such as PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure, and Chinese Biology Medicine, throughout February 2016. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strengths of the associations. RESULTS: Ten studies documenting a total of 4732 breast cancer cases and 5677 controls were included in this metaanalysis. The results indicated no significant association between XRCC1 Arg399Gln polymorphism and breast cancer risk in both total analysis and subgroup analysis stratified by geographical areas and source of controls. CONCLUSIONS: This meta-analysis provided evidence that XRCC1 Arg399Gln variant might not be risk alleles for breast cancer susceptibility in the Chinese population. Further studies conducted in other ethnic groups are required for definite conclusions.

Role of Medicinal Plants for Liver-Qi Regulation Adjuvant Therapy in Post-stroke Depression: A Systematic Review of Literature.

Current evidence demonstrated certain beneficial effects of medicinal herbs as an adjuvant therapy for post-stroke depression (PSD) in China; Chai-hu (Chinese Thorowax Root, Radix Bupleuri) is an example of a medicinal plant for Liver-Qi regulation (MPLR) in the treatment of PSD. Despite several narrative reports on the antidepressant properties of MPLR, it appears that there are no systematic reviews to summarize its outcome effects. Therefore, the aim of this review was to assess the effectiveness and safety of MPLR adjuvant therapy in patients with PSD. Seven databases were extensively searched from January 2000 until July 2016. Randomized control trials (RCTs) involving patients with PSD that compared treatment with and without MPLR were taken into account. The pooled effect estimates were calculated based on Cochrane Collaboration's software RevMan 5.3. Finally, 42 eligible studies with 3612 participants were included. Overall, MPLR adjuvant therapy showed a significantly higher effective rate (RR = 1.23; 95% CI = 1.19, 1.27; p < 0.00001) compared to those without. Moreover, the administration of MPLR was superior to abstainers regarding Hamilton Depression Scale (HAMD) score changes after 3 weeks (WMD = -4.83; 95% CI = -6.82, -2.83; p < 0.00001), 4 weeks (WMD = -3.25; 95% CI = -4.10, -2.40; p < 0.00001), 6 weeks (WMD = -4.04; 95% CI = -5.24, -2.84; p < 0.00001), 8 weeks (WMD = -4.72; 95% CI = -5.57, -3.87; p < 0.00001), and 12 weeks (WMD = -3.07; 95% CI = -4.05, -2.09; p < 0.00001). In addition, there were additive benefits in terms of response changes for the National Institutes of Health Stroke Scale (NIHSS) and other self-rating scores. No frequently occurring or serious adverse events were reported. We concluded that there is supporting evidence that adjuvant therapy with MPLR is effective in reducing the depressive symptoms and enhancing quality of life for patients with PSD. More well-designed RCTs are necessary to explore the role of MPLR in the treatment of PSD. Copyright © 2016 John Wiley & Sons, Ltd.

Association Studies of CYP1A1 Exon7 Polymorphism and -GSTM1 Interaction with Esophageal Cancer Risk: a Meta-Analysis in the Chinese Population.

BACKGROUND: Although many epidemiological studies have investigated the CYP1A1 exon7 polymorphism and -GSTM1 interaction with esophageal cancer (EC), definite conclusions cannot be drawn. This study was conducted to explore this association in the Chinese population using meta-analysis. METHODS: Relevant studies were identified from PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure, and Chinese Biology Medicine databases published through August 2015. The association of CYP1A1 exon7 polymorphisms and EC risk was estimated by odds ratio (ORs) with 95% confidence intervals (CIs). In addition, the interaction between the CYP1A1 exon7 and GSTM1 genotypes was assessed. RESULTS: A total of 13 case-control studies including 1781 EC cases and 1996 controls were included in this metaanalysis. Overall, significantly increased EC risk was associated with the CYP1A1 exon7 polymorphism (G vs. A OR = 1.36, 95% CI = 1.14 - 1.64; GG vs. AA: OR = 1.85, 95% CI = 1.22 - 2.79; GG vs. AG: OR = 1.41, 95% CI = 1.01 - 1.96; GG + AG vs. AA: OR = 1.47, 95% CI = 1.28 - 1.68; GG vs. AA + AG: OR = 1.60, 95% CI = 1.10 - 2.31). In a subgroup analyses stratified by geographic areas, histopathology type and source of controls, the significant risk was found in hospital-based population, in South and North China. Analysis of CYP1A1- GSTM1 interaction did find synergistic interaction between these two genes. CONCLUSIONS: This meta-analysis provides the evidence that CYP1A1 exon7 polymorphism may contribute to the EC development in the Chinese population, and CYP1A1- GSTM1 interaction might elevate the risk.

A regulatory pathway, ecdysone-transcription factor relish-cathepsin L, is involved in insect fat body dissociation.

Insect fat body is the organ for intermediary metabolism, comparable to vertebrate liver and adipose tissue. Larval fat body is disintegrated to individual fat body cells and then adult fat body is remodeled at the pupal stage. However, little is known about the dissociation mechanism. We find that the moth Helicoverpa armigera cathepsin L (Har-CL) is expressed heavily in the fat body and is released from fat body cells into the extracellular matrix. The inhibitor and RNAi experiments demonstrate that Har-CL functions in the fat body dissociation in H. armigera. Further, a nuclear protein is identified to be transcription factor Har-Relish, which was found in insect immune response and specifically binds to the promoter of Har-CL gene to regulate its activity. Har-Relish also responds to the steroid hormone ecdysone. Thus, the dissociation of the larval fat body is involved in the hormone (ecdysone)-transcription factor (Relish)-target gene (cathepsin L) regulatory pathway.

ß-Actin as a loading control: Less than 2 µg of total protein should be loaded.

For the purpose of data normalization in Western blot analysis, journal editors and reviewers usually require authors to reprobe the Western blot membrane with a ß-actin-specific antibody after detecting the target protein. In most cases, however, ß-actin is overloaded, which results in a failure to detect differences in protein loading. In this study, we attempted to optimize the amount of protein loaded for ß-actin detection to permit suitable Western blot analysis data normalization. Our data suggest that less than 2 µg of total protein should be loaded when ß-actin is used as a loading control. We also suggest avoiding reprobing the membrane with a ß-actin-specific antibody.

Glutathione-S-transferases M1/T1 gene polymorphisms and endometriosis: a meta-analysis in Chinese populations.

In view of the controversies surrounding the glutathione-S-transferases (GST) M1/T1-endometriosis association, a meta-analysis of the GSTM1/GSTT1 genetic association studies of endometriosis was performed in Chinese populations. PubMed, Springer Link, OvidSP, and Chinese databases were searched for related studies. A total of nine studies on GSTM1-endometriosis involved 874 cases and 997 controls, and five studies on GSTT1 involved 404 cases and 513 controls were included in this meta-analysis. Overall, the null genotype of GSTM1/GSTT1 was significantly related to endometriosis risk in Chinese populations (GSTM1, OR = 2.21, 95% CI: 1.22-4.01; GSTT1, OR = 2.31, 95% CI: 1.34-3.99). In subgroup analyses stratified by ethnicity and source of controls, the same results were observed in Chinese Han and population-based studies. The sensitivity analysis confirmed the reliability and stability of the meta-analysis. No publication bias was found among studies by Egger's test. In conclusion, our meta-analysis supports that the GSTM1/GSTT1 null genotype might contribute to individual susceptibility to endometriosis in Chinese populations, especially in Chinese Han.

Cross-talk between the fat body and brain regulates insect developmental arrest.

Developmental arrest, a critical component of the life cycle in animals as diverse as nematodes (dauer state), insects (diapause), and vertebrates (hibernation), results in dramatic depression of the metabolic rate and a profound extension in longevity. Although many details of the hormonal systems controlling developmental arrest are well-known, we know little about the interactions between metabolic events and the hormones controlling the arrested state. Here, we show that diapause is regulated by an interplay between blood-borne metabolites and regulatory centers within the brain. Gene expression in the fat body, the insect equivalent of the liver, is strongly suppressed during diapause, resulting in low levels of tricarboxylic acid (TCA) intermediates circulating within the blood, and at diapause termination, the fat body becomes activated, releasing an abundance of TCA intermediates that act on the brain to stimulate synthesis of regulatory peptides that prompt production of the insect growth hormone ecdysone. This model is supported by our success in breaking diapause by injecting a mixture of TCA intermediates and upstream metabolites. The results underscore the importance of cross-talk between the brain and fat body as a regulator of diapause and suggest that the TCA cycle may be a checkpoint for regulating different forms of animal dormancy.

Homeodomain POU and Abd-A proteins regulate the transcription of pupal genes during metamorphosis of the silkworm, Bombyx mori.

A cascade of 20-hydroxyecdysone-mediated gene expression and repression initiates larva-to-pupa metamorphosis. We recently showed that two transcription factors, BmPOUM2 and BmßFTZ-F1, bind to the cis-regulatory elements in the promoter of the gene coding for cuticle protein, BmWCP4, and regulate its expression during Bombyx mori metamorphosis. Here we show that down-regulation of BmPOUM2 expression by RNA interference during the wandering stage resulted in failure to complete metamorphosis. The thorax epidermis of RNA interference-treated larvae became transparent, wing disc growth and differentiation were arrested, and the larvae failed to spin cocoons. Quantitative real-time PCR analysis showed that expression of the genes coding for pupal-specific wing cuticle proteins BmWCP1, BmWCP2, BmWCP3, BmWCP4, BmWCP5, BmWCP6, BmWCP8, and BmWCP9 were down-regulated in BmPOUM2 dsRNA-treated animals, whereas overexpression of BmPOUM2 protein increased the expression of BmWCP4, BmWCP5, BmWCP6, BmWCP7, and BmWCP8. Pull-down assays, far-Western blot, and electrophoretic mobility shift assay showed that the BmPOUM2 protein interacted with another homeodomain transcription factor, BmAbd-A, to induce the expression of BmWCP4. Immunohistochemical localization of BmPOUM2, BmAbd-A, and BmWCP4 proteins revealed that BmAbd-A and BmPOUM2 proteins are colocalized in the wing disc cell nuclei, whereas BmWCP4 protein is localized in the cytoplasm. Together these data suggest that BmPOUM2 interacts with the homeodomain transcription factor BmAbd-A and regulates the expression of BmWCP4 and probably other BmWCPs to complete the larva-to-pupa transformation. Although homeodomain proteins are known to regulate embryonic development, this study showed that these proteins also regulate metamorphosis.

Polycomb repressive complex 2 (PRC2) protein ESC regulates insect developmental timing by mediating H3K27me3 and activating prothoracicotropic hormone gene expression.

The decision made by insects to develop into adults or halt development (enter diapause and prolong lifespan) is commonly based on environmental signals that provide reliable predictors of future seasons of adversity. For example, the short day lengths of early autumn accurately foretell the advent of winter, but little is known about the molecular mechanisms that preside over the hormonal events dictating whether the insect proceeds with development or enters diapause. In Helicoverpa armigera we show that day length affects H3K27me3 by affecting polycomb repressive complex 2 (PRC2) protein extra sex comb (ESC) and regulates the prothoracicotropic hormone (PTTH) gene, thus directly influencing developmental timing. ESC expression in brains of developing (nondiapause) pupae is higher than in brains from diapausing pupae. High ESC expression is localized in two pairs of PTTH neurosecretory cells, and H3K27me3 recruits on the PTTH promoter. Double strand ESC and PRC2 inhibitor (DzNep) treatment in vitro show that ESC triggers PTTH promoter activity, which in turn depends on PRC2 methyltransferase activity. Injection of DzNep into pupae programmed for development reduces the H3K27me3 mark and PTTH gene expression, thereby delaying development. Although ESC is best known as a transcriptional repressor, our results show that ESC prompts development and metamorphosis. We believe this is the first report showing that the PRC2 complex functions as an activator and that a low level of H3K27me3 can prolong lifespan (i.e. induce diapause) by controlling PTTH gene expression in insects.

Traditional Chinese medicine versus western medicine as used in China in the management of rheumatoid arthritis: a randomized, single-blind, 24-week study.

This study is designed to compare the efficacy and safety of traditional Chinese medicine (TCM) with western medicine (WM) in the management of rheumatoid arthritis (RA). This is a 24-week, randomized, multicenter, single-blind study comparing TCM with WM (as used in China) carried out between June 2002 and December 2004 in nine research centers in China, involving 489 patients. Patients were randomized to receive TCM (n = 247), MTX and SSZ (n = 242). MTX was started at a dose of 5 mg to a final dose of 7.5-15 mg weekly. The maintenance dose was 2.5-7.5 mg weekly. The starting dose of SSZ was 0.25 g bid, increasing by 0.25 g a day once a week to a final dose of 0.5-1 g qid. The maintenance dose was 0.5 g tid to qid. Primary end point was the proportion of patients with response according to the American College of Rheumatology 20 % improvement criteria (ACR20) at weeks 24. At 24 weeks, ACR20 responses were 53.0 % in TCM group and 66.5 % in WM group, (P < 0.001) at 24 weeks. ACR 50 responses were 31.6 % of TCM group and 42.6 % in WM group, (P = 0.01). ACR70 responses were 12.6 % in TCM group and 17.4 % in WM group, (P = 0.14). Side effects were observed more frequently in WM group. In this study, ACR20, ACR50 responses at 24 weeks were significantly better in the WM treated group, by intention to treat (ITT) and per protocol analysis. The ACR 70 response showed no significant difference between the two groups. TCM, while effective in treating RA, appears to be less effective than WM in controlling symptoms, but TCM is associated with fewer side effects.

The protease Lon prolongs insect lifespan by responding to reactive oxygen species and degrading mitochondrial transcription factor A.

Diapause is a widespread adaptation of insects that enables them to survive during unfavorable seasons and is characterized by suppressed metabolism and increased lifespan. Previous works have demonstrated that high levels of reactive oxygen species (ROS) and hypoxia-inducible factor-1α (HIF-1α) in the pupal brain of the moth Helicoverpa armigera induce diapause and extend lifespan by downregulating mitochondrial transcription factor A (TFAM). However, the molecular mechanisms of ROS-HIF-1α regulating metabolic activity to extend lifespan are still poorly understood. Here, we show that the mitochondrial abundance in diapause-type pupal brains is markedly lower than that in their nondiapause-type pupae, suggesting that ROS-HIF-1α signaling negatively regulates the number of mitochondria. The protease Lon, a major mitochondrial matrix protease, can respond to ROS signals. It is activated by transcription factor HIF-1α, which specifically binds the LON promoter to promote its expression. A high level of LON mediates the degradation of TFAM, which is a crucial factor in regulating mitochondrial abundance and metabolic activity. We believe this is the first report that a previously unrecognized regulatory pathway, ROS-HIF-1α-LON-TFAM, reduces mitochondrial activity to induce diapause, extending insect lifespan.

Integrated multi-omics analysis reveals liver metabolic reprogramming by fish iridovirus and antiviral function of alpha-linolenic acid.

Iridovirus poses a substantial threat to global aquaculture due to its high mortality rate; however, the molecular mechanisms underpinning its pathogenesis are not well elucidated. Here, a multi-omics approach was applied to groupers infected with Singapore grouper iridovirus (SGIV), focusing on the roles of key metabolites. Results showed that SGIV induced obvious histopathological damage and changes in metabolic enzymes within the liver. Furthermore, SGIV significantly reduced the contents of lipid droplets, triglycerides, cholesterol, and lipoproteins. Metabolomic analysis indicated that the altered metabolites were enriched in 19 pathways, with a notable down-regulation of lipid metabolites such as glycerophosphates and alpha-linolenic acid (ALA), consistent with disturbed lipid homeostasis in the liver. Integration of transcriptomic and metabolomic data revealed that the top enriched pathways were related to cell growth and death and nucleotide, carbohydrate, amino acid, and lipid metabolism, supporting the conclusion that SGIV infection induced liver metabolic reprogramming. Further integrative transcriptomic and proteomic analysis indicated that SGIV infection activated crucial molecular events in a phagosome-immune depression-metabolism dysregulation-necrosis signaling cascade. Of note, integrative multi-omics analysis demonstrated the consumption of ALA and linoleic acid (LA) metabolites, and the accumulation of L-glutamic acid (GA), accompanied by alterations in immune, inflammation, and cell death-related genes. Further experimental data showed that ALA, but not GA, suppressed SGIV replication by activating antioxidant and anti-inflammatory responses in the host. Collectively, these findings provide a comprehensive resource for understanding host response dynamics during fish iridovirus infection and highlight the antiviral potential of ALA in the prevention and treatment of iridoviral diseases.

The complete mitochondrial genome of the Baishanzu horned toad Boulenophrys baishanzuensis (Anura: Megophryidae).

The mitochondrial genome (mitogenome) of Boulenophrys baishanzuensis (Anura: Megophryidae) was sequenced by the Illumina platform. The assembled circular mitogenome of B. baishanzuensis had a total length of 17,040 bp, with a GC content of 41.25%. It consisted of 13 protein-coding genes (PCGs), two rRNA genes, 22 tRNA genes, and a D-loop region. The majority of the PCGs were encoded by the H-strand, while one PCG (nad6) and eight tRNA genes (tRNA-Gln, tRNA-Ala, tRNA-Asn, tRNA-Cys, tRNA-Tyr, tRNA-Ser2, tRNA-Glu, and tRNA-Pro) were encoded in the L-strand. Phylogenetic analysis revealed that the newly sequenced species formed a clade with other Boulenophrys species, while the genus Boulenophrys itself formed a sister group with the genus Atympanophrys.
