Long noncoding RNA LOC646029 functions as a ceRNA to suppress ovarian cancer progression through the miR-627-3p/SPRED1 axis / 医学前沿

Long noncoding RNAs (lncRNAs) play a crucial regulatory role in the development and progression of multiple cancers. However, the potential mechanism by which lncRNAs affect the recurrence and metastasis of ovarian cancer remains unclear. In the current study, the lncRNA LOC646029 was markedly downregulated in metastatic ovarian tumors compared with primary tumors. Gain- and loss-of-function assays demonstrated that LOC646029 inhibits the proliferation, invasiveness, and metastasis of ovarian cancer cells in vivo and in vitro. Moreover, the downregulation of LOC646029 in metastatic ovarian tumors was strongly correlated with poor prognosis. Mechanistically, LOC646029 served as a miR-627-3p sponge to promote the expression of Sprouty-related EVH1 domain-containing protein 1, which is necessary for suppressing tumor metastasis and inhibiting KRAS signaling. Collectively, our results demonstrated that LOC646029 is involved in the progression and metastasis of ovarian cancer, which may be a potential prognostic biomarker.

Hydrophobicity of the C-terminal GPI-anchor Attachment Signals Determines ER-associated Degradation Pathway of Precursor Proteins / 中国生物化学与分子生物学报

More than 150 glycosylphosphatidylinositol (GPI)-anchored proteins (GPI-APs) are expressed in mammalian cells and involved in various physiological processes such as immune recognition, cell communication and signal transduction. GPI is transferred to proteins in the endoplasmic reticulum (ER). When GPI-anchoring is impaired, precursor proteins are thought to be degraded through ER-associated degradation (ERAD). However, the mechanism of their degradation in ERAD remains unclear. To investigate the impact of ERAD pathways on degradation of GPI precursor proteins, we used series of knockout (KO) human embryonic kidney 293 (HEK293) cells defective in PIGS gene, which encodes a GPI transamidase complex subunit, combined with KO in HRD1 (PIGS-HRD1-KO) or GP78 (PIGSGP78-KO), which encodes the E3 ubiquitin ligases for the ERAD pathways. We compared the stability of 16 GPI precursor proteins in the ERAD-deficient cells with the parental PIGS-KO cells. Western blotting data showed that the GPI precursor proteins were stabilized in either PIGS-HRD1-KO (I

Genome sizes of four important medicinal species in Kadsura by flow cytometry / 中草药·英文版

Objective: Dianjixueteng is a geoherb in Yunnan Province, the source plant of which is Kadsura interior. However, the formation of this geoherb is not clear in genetic mechanism, in which genome size is the first step that should be known on the genomic level. In this study we aimed to estimate the genome sizes of source plants of K. interior and three related herbs K. heteroclita, K. longipedunculata, and K. coccinea by flow cytometry (FCM) and make a comparison. Methods: The genome sizes of K. interior, K. heteroclita, K. longipedunculata and K. coccinea, i.e., the source plants of Dianjixueteng and its relative medicinal materials, were estimated by FCM. The nuclei of K. interior were isolated using modified LB01 buffer, for the rest species, by the Galbraith's buffer. Results: The genome sizes of K. interior, K. heteroclita, K. longipedunculata, and K. coccinea were 7.36, 7.12, 7.01, and 5.15 pg/1C, respectively. Genome size of K. interior had no significant variation with those of K. heteroclita and K. longipedunculata (P = 0.296), which was significantly larger than that of K. coccinea. Conclusion: Genome size can not distinguish K. interior from K. heteroclita and K. longipedunculata, but could distinguish them from K. coccinea, which lays the foundation for future studies on genetic mechanism of the geoherb formation.

Identification and characterization of DIR gene family in Schisandra chinensis / 中国中药杂志

Dirigent(DIR) proteins are involved in the biosynthesis of lignin, lignans, and gossypol in plants and respond to biotic and abiotic stresses. Based on the full-length transcriptome of Schisandra chinensis, bioinformatics methods were used to preliminarily identify the DIR gene family and analyze the physico-chemical properties, subcellular localization, conserved motifs, phylogeny, and expression patterns of the proteins. The results showed that a total of 34 DIR genes were screened and the encoded proteins were 156-387 aa. The physico-chemical properties of the proteins were different and the secondary structure was mainly random coil. Half of the DIR proteins were located in chloroplast, while the others in extracellular region, endoplasmic reticulum, cytoplasm, etc. Phylogenetic analysis of DIR proteins from S. chinensis and the other 8 species such as Arabidopsis thaliana, Oryza sativa, and Glycine max demonstrated that all DIR proteins were clustered into 5 subfamilies and that DIR proteins from S. chinensis were in 4 subfamilies. DIR-a subfamily has the unique structure of 8 β-sheets, as verified by multiple sequence alignment. Finally, through the analysis of the transcriptome of S. chinensis fruit at different development stages, the expression pattern of DIR was clarified. Combined with the accumulation of lignans in fruits at different stages, DIR might be related to the synthesis of lignans in S. chinensis. This study lays a theoretical basis for exploring the biological functions of DIR genes and elucidating the biosynthesis pathway of lignans in S. chinensis.

The method is simple, accurate and reproducible, and can be used for determining the content of six major bioactive isosteroidal alkaloids.

Cloning and expression analysis of 2-oxoglutarate-dependent dioxygenase from Schisandra chinensis / 药学学报

The 2-oxoglutarate-dependent dioxygenase (2-ODD) gene is regarded as the key enzyme gene involved with aryl naphthalene lignan-podophyllotoxin synthesis. To study the expression pattern and function of the Sc2-ODD gene, a full-length cDNA of the gene was cloned. Bioinformatic analysis, the expression pattern, and prokaryotic expression and purification were implemented. The open reading frame of Sc2-ODD gene was 1 077 bp and encoded 358 amino acids with a molecular weight of 40.16 kD. The Sc2-ODD protein contained the conserved 2OG-FeII-oxy sequence of the 2-ODD protein. The results of phylogenetic analysis revealed that Sc2-ODD is most closely related to Corchorus olitorius 2-ODD. qRT-PCR results showed that Sc2-ODD expression displayed obvious up-regulation at the fruit-swelling stage, then down-regulation in the fruit-coloring period. The Sc2-ODD gene was cloned into the bacterial expression vector pGS21T, the recombinant Sc2-ODD protein was expressed in Escherichia coli Rosetta (DE3) cells and the fusion protein was obtained and purified by GST fusion protein purification technology. This study will lay a foundation for further research on the function and expressional regulation of the Sc2-ODD gene in the aryl naphthalene lignans biosynthesis pathway, and also provides a scientific basis for improving the lignan content and the medicinal quality of Schisandra chinensis using plant genetic engineering.

Research Progress on Application and Mechanism of Traditional Chinese Medicine in Gout / 中国实验方剂学杂志

Gout is the second largest metabolic disease after diabetes, with a high incidence worldwide. Gout is a common and complex arthritic disease that, if left untreated, can damage joints and, in severe cases, lead to kidney stones and even life-threatening kidney failure. Although western medicine has also made significant achievements in the treatment of gout, it is often accompanied by gastrointestinal reactions, liver injury and other adverse reactions, and is prone to relapse after drug withdrawal, making the radical treatment of gout a difficult problem. Traditional Chinese medicine (TCM) used in gout have relatively long history, TCM has the characteristics of multiple ingredients targets, not only can produce related enzyme activity by inhibiting the uric acid(UA) and lowering uric acid generation, also can reduce uric acid by promoting uric acid excretion, except the uric acid reduction most applied in gout neighborhood of TCM can effectively reduce joint inflammation. TCM is mild, and the incidence of adverse reactions in the treatment of gout is significantly lower than that of western medicine. Some TCM can even play a role while protecting the kidney, so TCM is expected to solve the problem of treating gout. In recent years, a large number of studies have been conducted on the application of TCM in the gout neighborhood at home and abroad. By summarizing the studies on the application of TCM in the gout disease in the past 10 years, the mechanism of action and material basis have been summarized and analyzed, in the hope of providing references for the studies on the prevention and treatment of gout by TCM.
