The microRNA, miR-29c, participates in muscle development through targeting the

Weiya ZHANG,Wei WEI,Yuanyuan ZHAO,Shuhong ZHAO,Xinyun LI

Frontiers of Agricultural Science and Engineering 2015, Volume 2, Issue 4,   Pages 311-317 doi: 10.15302/J-FASE-2015075

Abstract: Previous studies indicated that miR-29c is important for muscle development in mice and human, but its role in pigs is unknown. In this study, we detected the expression of miR-29c in Meishan longissimus lumborum (LL) muscle. The results showed that miR-29c was gradually upregulated during development of skeletal muscle in pig. Moreover, the expression of and genes, which were confirmed to be targeted by miR-29c in mice, was decreased along with muscle development. Furthermore, the expression level of miR-29c was significantly higher in adult Meishan pigs than Large White pigs, while the expression of and genes was significantly lower in Meishan pigs. These results indicated that the expression pattern of miR-29c was opposite to that of and genes in pigs. Also, the luciferase assay indicated that miR-29s can target the gene in pigs. In addition, we identified a T to C mutation in the primary transcript of miR-29c, which was associated with the postmortem muscle pH in pigs. Based on these results, we concluded that miR-29c is also important in skeletal muscle development of pigs.

Probes and nano-delivery systems targeting NAD(P)H:quinone oxidoreductase 1: a mini-review

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 2,   Pages 123-138 doi: 10.1007/s11705-022-2194-7

Abstract: The two-electron cytoplasmic reductase NAD(P)H:quinone oxidoreductase 1 is expressed in many tissues. NAD(P)H:quinone oxidoreductase 1 is well-known for being highly expressed in most cancers. Therefore, it could be a target for cancer therapy. Because it is a quinone reductase, many bioimaging probes based on quinone structures target NAD(P)H:quinone oxidoreductase 1 to diagnose tumours. Its expression is higher in tumours than in normal tissues, and using target drugs such as β-lapachone to reduce side effects in normal tissues can help. However, the physicochemical properties of β-lapachone limit its application. The problem can be solved by using nanosystems to deliver β-lapachone. This mini-review summarizes quinone-based fluorescent, near-infrared and two-photon fluorescent probes, as well as nanosystems for delivering the NAD(P)H:quinone oxidoreductase 1-activating drug β-lapachone. This review provides valuable information for the future development of probes and nano-delivery systems that target NAD(P)H:quinone oxidoreductase 1.

Repurposed benzydamine targeting CDK2 suppresses the growth of esophageal squamous cell carcinoma

Frontiers of Medicine 2023, Volume 17, Issue 2,   Pages 290-303 doi: 10.1007/s11684-022-0956-8

Abstract: Esophageal squamous cell carcinoma (ESCC) is one of the leading causes of cancer death worldwide. It is urgent to develop new drugs to improve the prognosis of ESCC patients. Here, we found benzydamine, a locally acting non-steroidal anti-inflammatory drug, had potent cytotoxic effect on ESCC cells. Benzydamine could suppress ESCC proliferation in vivo and in vitro. In terms of mechanism, CDK2 was identified as a target of benzydamine by molecular docking, pull-down assay and in vitro kinase assay. Specifically, benzydamine inhibited the growth of ESCC cells by inhibiting CDK2 activity and affecting downstream phosphorylation of MCM2, c-Myc and Rb, resulting in cell cycle arrest. Our study illustrates that benzydamine inhibits the growth of ESCC cells by downregulating the CDK2 pathway.

Rhizosphere immunity: targeting the underground for sustainable plant health management

Zhong WEI, Ville-Petri FRIMAN, Thomas POMMIER, Stefan GEISEN, Alexandre JOUSSET, Qirong SHEN

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 3,   Pages 317-328 doi: 10.15302/J-FASE-2020346

Abstract:

Managing plant health is a great challenge for modern food production and is further complicated by the lack of common ground between the many disciplines involved in disease control. Here we present the concept of rhizosphere immunity, in which plant health is considered as an ecosystem level property emerging from networks of interactions between plants, microbiota and the surrounding soil matrix. These interactions can potentially extend the innate plant immune system to a point where the rhizosphere immunity can fulfil all four core functions of a full immune system: pathogen prevention, recognition, response and homeostasis. We suggest that considering plant health from a meta-organism perspective will help in developing multidisciplinary pathogen management strategies that focus on steering the whole plant-microbe-soil networks instead of individual components. This might be achieved by bringing together the latest discoveries in phytopathology, microbiome research, soil science and agronomy to pave the way toward more sustainable and productive agriculture.

Mechanistic and therapeutic advances in non-alcoholic fatty liver disease by targeting the gut microbiota

Ruiting Han, Junli Ma, Houkai Li

Frontiers of Medicine 2018, Volume 12, Issue 6,   Pages 645-657 doi: 10.1007/s11684-018-0645-9

Abstract: Non-alcoholic fatty liver disease (NAFLD) is one of the most common metabolic diseases currently in the context of obesity worldwide, which contains a spectrum of chronic liver diseases, including hepatic steatosis, non-alcoholic steatohepatitis and hepatic carcinoma. In addition to the classical “Two-hit” theory, NAFLD has been recognized as a typical gut microbiota-related disease because of the intricate role of gut microbiota in maintaining human health and disease formation. Moreover, gut microbiota is even regarded as a “metabolic organ” that play complementary roles to that of liver in many aspects. The mechanisms underlying gut microbiota-mediated development of NAFLD include modulation of host energy metabolism, insulin sensitivity, and bile acid and choline metabolism. As a result, gut microbiota have been emerging as a novel therapeutic target for NAFLD by manipulating it in various ways, including probiotics, prebiotics, synbiotics, antibiotics, fecal microbiota transplantation, and herbal components. In this review, we summarized the most recent advances in gut microbiota-mediated mechanisms, as well as gut microbiota-targeted therapies on NAFLD.

Frontiers of Agricultural Science and Engineering 2019, Volume 6, Issue 1,   Pages 66-72 doi: 10.15302/J-FASE-2018229

Abstract:

Porcine viral diarrhea is an acute and highly contagious enteric disease of pigs that causes huge economic losses worldwide. Porcine epidemic diarrhea virus (PEDV) and transmissible gastroenteritis virus (TGEV) are the main pathogens responsible for piglet viral diarrhea. However, currently there is no specific drug available for the effective treatment of viral diarrhea. Therefore, it is necessary to seek an effective method to diminish PEDV and TGEV infection rates. RNA interference has been applied successfully to inhibit the virus replication. It provides a potential strategy for breeding resistant pigs. In this study, four promoters and four short hairpin RNA (shRNA) vectors with LoxP sites at each end of the selectable marker genes were constructed to target PEDV and TGEV. These vectors were then transfected into porcine fetal fibroblasts, G418 resistant transfectants were confirmed by PCR and transgenic SCNT porcine blastocysts were obtained. These results have paved the way for future production of marker-free transgenic resistant to PEDV and TEGV pigs by SCNT.

Frontiers of Medicine 2017, Volume 11, Issue 4,   Pages 449-461 doi: 10.1007/s11684-017-0589-5

Abstract:

In recent years, unexpected outbreaks of infectious diseases caused by emerging and re-emerging viruses have become more frequent, which is possibly due to environmental changes. These outbreaks result in the loss of life and economic hardship. Vaccines and therapeutics should be developed for the prevention and treatment of infectious diseases. In this review, we summarize and discuss the latest progress in the development of small-molecule viral inhibitors against highly pathogenic coronaviruses, including severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus, Ebola virus, and Zika virus. These viruses can interfere with the specific steps of viral life cycle by blocking the binding between virus and host cells, disrupting viral endocytosis, disturbing membrane fusion, and interrupting viral RNA replication and translation, thereby demonstrating potent therapeutic effect against various emerging and re-emerging viruses. We also discuss some general strategies for developing small-molecule viral inhibitors.

Frontiers of Medicine 2007, Volume 1, Issue 4,   Pages 359-363 doi: 10.1007/s11684-007-0069-4

Abstract: The aim of this study was to investigate the role of pirh2 (p53-induced RING-H2) protein in the proliferation, apoptosis and cell cycle control of the lung cancer cell line A549. Pirh2 expression was detected by immunofluorescence, Western blot analysis and real-time polymerase chain reaction (PCR). Cell proliferation was assessed by cell counting kit-8 (CCK-8). Cell cycle control and apoptosis were analyzed by flow cytometry. The results showed that pirh2 was expressed in the cytoplasm of A549 cells. The inhibition of pirh2 expression by siRNA (psiRNA-pirh2) resulted in reduced cell proliferation and increased apoptosis. In addition, the number of G/G phase cells was increased but G/M cells were not affected significantly. Taken together, the inhibition of pirh2 expression in the lung adenocarcinoma cell line A549 resulted in reduced tumor cell growth via the inhibition of cell proliferation, the activation of apoptosis and the interruption of cell cycle transition.
