Human ESC-derived vascular cells promote vascular regeneration in a HIF-1α dependent manner

Hypoxia-inducible factor (HIF-1α), a core transcription factor responding to changes in cellular oxygen levels, is closely associated with a wide range of physiological and pathological conditions. However, its differential impacts on vascular cell types and molecular programs modulating human vascular homeostasis and regeneration remain largely elusive. Here, we applied CRISPR/Cas9-mediated gene editing of human embryonic stem cells and directed differentiation to generate HIF-1α-deficient human vascular cells including vascular endothelial cells, vascular smooth muscle cells, and mesenchymal stem cells (MSCs), as a platform for discovering cell type-specific hypoxia-induced response mechanisms. Through comparative molecular profiling across cell types under normoxic and hypoxic conditions, we provide insight into the indispensable role of HIF-1α in the promotion of ischemic vascular regeneration. We found human MSCs to be the vascular cell type most susceptible to HIF-1α deficiency, and that transcriptional inactivation of ANKZF1, an effector of HIF-1α, impaired pro-angiogenic processes. Altogether, our findings deepen the understanding of HIF-1α in human angiogenesis and support further explorations of novel therapeutic strategies of vascular regeneration against ischemic damage.

Research progress of optic disc tilt in high myopia / 国际眼科杂志(Guoji Yanke Zazhi)

With the prevalence of myopia in Asia, the prevalence of high myopia is gradually increasing, and high myopia has undoubtedly become a public health problem in Asia and even around the globe. As a relatively common pathological change in the eyes of patients with high myopia, optic disc tilt may also become a risk factor for diseases such as glaucoma and macular degeneration, thereby increasing the risk of visual impairment. However, the mechanism of optic disc tilt in high myopia and the role of optic disc tilt in the aggravation of high myopia complications still needs to be further explored. Therefore, this article collects and organizes relevant literatures on optic disc tilt, and makes a comprehensive discussion on the mechanism of optic disc shape changing caused by high myopia and the impact on various complications, so as to provide a certain basis for clinical diagnosis and treatment of high myopia and its complications.

Probing the Impact of Whole Intestinal Microbiota Transplantation from Alzheimer's Disease Model Mice on the Ileal Microenvironment Based on the “Interior-Exterior Relationship Exists Between Heart and Small Intestine” / 中山大学学报(医学科学版)

ObjectiveTo investigate whether the whole intestinal microbiota transplantation in Alzheimer's disease （AD） model mice has more significant effects on ileum intestinal microenvironment in normal mice under the guidance of the theory of traditional Chinese medicine that "interior-exterior relationship exists between the heart and small intestine". MethodsThe whole intestinal microbiota of fourteen 6-month-old specific pathogen free male APP/PS1 double-transgenic AD model mice was transplanted into the gut of six normal C57BL/6J mice of the same age and background treated with mixed antibiotics for 14 days. Then， after 14 days of normal rearing， the mice were sacrificed. Next， the pathological changes in the ileum and colon were observed， and the composition and diversity of the ileal and colonic microbiota was analyzed by sequencing. ResultsAfter the whole intestinal microbiota of AD mice was transplanted into normal mice， pathological analysis showed that only the ileum tissue had mucosal damage and crypt gland epithelial cell degeneration， necrosis， and shedding. Moreover， the microbiota analysis found that only the number of genera （P<0.01）， Chao1 index （P<0.01） and Simpson index of ileal microbiota in normal mice decreased （P<0.01）， and the composition of intestinal microbiota was quite similar to that of AD model mice. ConclusionUnder the effect of whole gut microbiota transplantation in AD mice， the diversity and composition of ileal microbiota change more than that of colonic microbiota in normal mice， and at the same time， it results in pathological damage to the ileal mucosa， indicating that the ileal microenvironment may be more closely related to the occurrence and development of AD， which is highly consistent with the traditional Chinese medicine theory of "interior-exterior relationship between heart and small intestine".

Blaps rynchopetera affects proliferation, migration, and invasion of non-small cell lung cancer: a study based on network pharmacology and in vivo and in vitro experiments / 中国中药杂志

Network pharmacology, molecular docking, and in vivo and in vitro experiments were employed to study the molecular mechanism of Blaps rynchopetera Fairmaire in the treatment of non-small cell lung cancer(NSCLC). The components of B. rynchopetera were collected by literature review, and the active components were screened out through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). PharmMapper was used to obtain the targets of the active components. The targets of NSCLC were obtained from DrugBank, GeneCards, OMIM, TTD, and PharmGKB. The Venn diagram was drawn to identify the common targets shared by the active components of B. rynchopetera and NSCLC. The "drug component-target" network and protein-protein interaction(PPI) network were constructed by Cytoscape, and the key targets were screened by Centiscape. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment of the above key targets were performed by DAVID. AutoDock and PyMOL were used for the molecular docking between the key targets and corresponding active components. A total of 31 active components, 72 potential targets, and 11 key targets of B. rynchopetera against NSCLC were obtained. The active components of B. rynchopetera had good binding activity with key targets. Further, the serum containing B. rynchopetera was prepared and used to culture human lung adenocarcinoma A549 cells. The CCK-8 assay was employed to determine the inhibition rates on the growth of A549 cells in blank control group and those exposed to different concentrations of B. rynchopetera-containing serum, cisplatin, and drug combination(B. rynchopetera-containing serum+cisplatin) for different time periods. The cell migration and invasion of A549 cells were detected by cell scratch assay and Transwell assay, respectively. Western blot was employed to determine the expression levels of B-cell lymphoma-2(Bcl-2), Bcl-2-associated X(Bax), caspase-3, cell division cycle 42(CDC42), proto-oncogene tyrosine-protein kinase SRC, and vascular endothelial growth factor(VEGF) in A549 cells. C57BL/6 mice were inoculated with Lewis cells and randomly assigned into a model control group, a B. rynchopetera group, a cisplatin group, and a drug combination(B. rynchopetera+cisplatin) group, with 12 mice per group. The body weight and the long diameter(a) and short diameter(b) of the tumor were monitored every other day during treatment, and the tumor volume(mm~3) was calculated as 0.52ab~2. After 14 days of continuous medication, the mice were sacrificed for the collection of tumor, spleen, and thymus, and the tumor inhibition rate and immune organ indexes were calculated. The tissue morphology of tumors was observed by hematoxylin-eosin(HE) staining, and the positive expression of Bax, Bcl-2, caspase-3, CDC42, SRC, and VEGF in the tumor tissue was detected by immunohistochemistry. The results indicated that B. rynchopetera and the drug combination regulated the expression levels of Bax, Bcl-2, caspase-3, CDC42, SRC, and VEGF to inhibit the proliferation, migration, and invasion of A549 cells and Lewis cells, thus playing a role in the treatment of NSCLC via multiple ways.

Single-cell transcriptomic atlas of mouse cochlear aging

Progressive functional deterioration in the cochlea is associated with age-related hearing loss (ARHL). However, the cellular and molecular basis underlying cochlear aging remains largely unknown. Here, we established a dynamic single-cell transcriptomic landscape of mouse cochlear aging, in which we characterized aging-associated transcriptomic changes in 27 different cochlear cell types across five different time points. Overall, our analysis pinpoints loss of proteostasis and elevated apoptosis as the hallmark features of cochlear aging, highlights unexpected age-related transcriptional fluctuations in intermediate cells localized in the stria vascularis (SV) and demonstrates that upregulation of endoplasmic reticulum (ER) chaperon protein HSP90AA1 mitigates ER stress-induced damages associated with aging. Our work suggests that targeting unfolded protein response pathways may help alleviate aging-related SV atrophy and hence delay the progression of ARHL.

ObjectiveTo investigate the effect of Huangqisan pellets （HQS） on the phosphatidylinositol-3 kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） signaling pathway and autophagy in the kidney of diabetic nephropathy （DN） rats. MethodDN rat model was established through high-fat diet combined with intraperitoneal injection of streptozotocin （35 mg·kg-1）. DN rats were randomly assigned into model group， irbesartan （0.027 g·kg-1） group， low-dose HQS （0.54 g·kg-1） group and high-dose HQS （1.08 g·kg-1） group. The levels of 24 h urinary total protein （UTP）， serum albumin （Alb）， serum creatinine （SCr）， urea nitrogen （BUN）， triglyceride （TG） and total cholesterol （TC） were measured after 12 weeks of continuous administration. The pathological changes of renal tissue were observed via hematoxylin-eosin （HE） staining. The expression of podocyte split diaphragm proteins nephrin and podocin in the renal tissue were detected by immunohistochemistry. The protein levels and phosphorylation of key proteins in PI3K/Akt/mTOR signaling pathway， as well as the expression of yeast Atg6 homolog （Beclin1） and microtubule-associated protein 1 light chain 3 （LC3） in the renal tissue were analyzed by Western blot. ResultCompared with the control group， the model group showcased increased 24 h UTP， SCr， BUN， TG， and TC levels and decreased Alb level （P<0.01）. After modeling， the rats showed granulosity of epithelial cells of renal tubules， thickening of capillary basement membrane， proliferation of mesangial cells， and sclerosis of glomerulus. Furthermore， modeling down-regulated the expression of nephrin and podocin in the podocyte hiatus of glomerulus （P<0.01） as well as the protein levels of p-PI3K， p-Akt， and p-mTOR and the autophagy markers LC3 and Beclin1 in renal tissue （P<0.01）. Compared with model group， irbesartan and HQS decreased the 24 h UTP， Cr， BUN， TG， and TC levels， increased the Alb level， and alleviated the pathological damage of kidney. Moreover， they up-regulated the expression of Nephrin and Podocin in the podocyte hiatus of glomerulus， as well as the protein levels of p-PI3K， p-Akt， p-mTOR， LC3， and Beclin1 in renal tissue （P<0.05， P<0.01）. ConclusionHQS may inhibit the PI3K/Akt/mTOR signaling pathway to enhance podocyte autophagy and protect the glomerulus， thus slowing down the development of DN.

Research Progress of Gypsum Ustum and Application of Calcium-containing Hemostatic Materials / 中国实验方剂学杂志

Mineral medicine is an indispensable part of traditional Chinese medicine and has a long history of application. Among them， mineral-based hemostatics have been widely applied for the treatment of various hemorrhagic diseases with extensive clinical experience and established efficacy. Gypsum Fibrosum （GF）， a commonly used mineral medicine in clinical， can clear away heat， and relieve anxiety and thirst. Gypsum Ustum （GU） is the processed product of GF after calcining at high temperature. It is mainly composed of anhydrous calcium sulfate （CaSO4） with the functions of moisturizing， promoting muscle growth， astringent sores and hemostasis. GU is often used externally to treat ulcer， itching， eczema， water and fire scalds， trauma bleeding， etc. Studies on the mechanism of hemostasis have shown that Ca2+ （coagulation factor Ⅳ） is involved in many key processes of the internal and external coagulation cascades and can prevent bleeding by regulating platelet activation and aggregation， and promoting the production of insoluble fibrin and the ultimate formation of a blood clot. GF and GU both contain Ca2+ which provide an important material basis of hemostatic effect for both compounds， but GU has a significant hemostatic effect， while GF has no hemostatic effect. After processing， the taste and efficacy of the GF have been obviously changed which reflects the characteristics of processing， but the processing mechanism of GU has not been fully clarified. Therefore， based on studies of GF before and after calcining， this paper focused on these aspects including calcining process， crystal form comparison， element content， efficacy comparison， and summarized various aspects of Ca2+ involved in hemostasis. In addition， the hemostatic properties of other calcium-containing mineral medicines and new calcium-containing hemostatic materials such as calcium alginate， mesoporous calcium silicate and nanogel hemostatic materials were also discussed. The paper aimed to provide a reference for elucidating processing mechanism and clinical dialectical use of GU， also to promote development of new calcium-containing hemostatic materials.

Ovarian cancer risk score predicts chemo-response and outcome in epithelial ovarian carcinoma patients / 부인종양

Objective@#Cytoreductive surgery followed by adjuvant chemotherapy is a standard frontline treatment for epithelial ovarian cancer (EOC). We aimed to develop an ovarian cancer risk score (OVRS) based on the expression of 10 ovarian-cancer-related genes to predict the chemoresistance, and outcomes of EOC patients. @*Methods@#We designed a case-control study with total 149 EOC women including 75 chemosensitives and 74 chemoresistants. Gene expression was measured using the quantitative real-time polymerase chain reaction. We tested for correlation between the OVRS and chemosensitivity or chemoresistance, disease-free survival (DFS), and overall survival (OS), and validated the OVRS by analyzing patients from the TCGA database. @*Results@#The chemosensitive group had lower OVRS than the chemoresistant group (5 vs.15, p≤0.001, Mann-Whitney U test). Patients with disease relapse (13 vs. 5, p60 months) of patients with OVRS ≥10 were significantly shorter than those of patients with OVRS <9). The high OVRS group also had significantly shorter median OS than the low OVRS group in 255 patients in the TCGA database (39 vs. 49 months, p=0.046). @*Conclusions@#Specific genes panel can be clinically applied in predicting the chemoresistance and outcome, and decision-making of epithelial ovarian cancer.
