Characterization of candidate factors associated with the metastasis and progression of high-grade serous ovarian cancer / 中华医学杂志(英文版)

BACKGROUND@#High-grade serous ovarian cancer (HGSOC) is the biggest cause of gynecological cancer-related mortality because of its extremely metastatic nature. This study aimed to explore and evaluate the characteristics of candidate factors associated with the metastasis and progression of HGSOC.@*METHODS@#Transcriptomic data of HGSOC patients' samples collected from primary tumors and matched omental metastatic tumors were obtained from three independent studies in the National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were selected to evaluate the effects on the prognosis and progression of ovarian cancer using data from The Cancer Genome Atlas (TCGA) database. Hub genes' immune landscapes were estimated by the Tumor Immune Estimation Resource (TIMER) database. Finally, using 25 HGSOC patients' cancer tissues and 10 normal fallopian tube tissues, immunohistochemistry (IHC) was performed to quantify the expression levels of hub genes associated with International Federation of Gynecology and Obstetrics (FIGO) stages.@*RESULTS@#Fourteen DEGs, ADIPOQ , ALPK2 , BARX1 , CD37 , CNR2 , COL5A3 , FABP4 , FAP , GPR68 , ITGBL1 , MOXD1 , PODNL1 , SFRP2 , and TRAF3IP3 , were upregulated in metastatic tumors in every database while CADPS , GATA4 , STAR , and TSPAN8 were downregulated. ALPK2 , FAP , SFRP2 , GATA4 , STAR , and TSPAN8 were selected as hub genes significantly associated with survival and recurrence. All hub genes were correlated with tumor microenvironment infiltration, especially cancer-associated fibroblasts and natural killer (NK) cells. Furthermore, the expression of FAP and SFRP2 was positively correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage, and their increased protein expression levels in metastatic samples compared with primary tumor samples and normal tissues were confirmed by IHC ( P = 0.0002 and P = 0.0001, respectively).@*CONCLUSIONS@#This study describes screening for DEGs in HGSOC primary tumors and matched metastasis tumors using integrated bioinformatics analyses. We identified six hub genes that were correlated with the progression of HGSOC, particularly FAP and SFRP2 , which might provide effective targets to predict prognosis and provide novel insights into individual therapeutic strategies for HGSOC.

Research advances in the role of MAPK cascade in regulation of cell growth, immunity, inflammation, and cancer / 中南大学学报(医学版)

Mitogen-activated protein kinase (MAPK) cascade system is one of the highly conserved signal systems in eukaryotic cells, which participates in the regulation of many biological processes. Under the stimulation of different signals (such as cytokines, neurotransmitters, and hormones), MAPK cascade activates downstream targets and controls a variety of cellular processes, including growth, immunity, inflammation, and stress response. In different cells, the effects of MAPK cascade on cells vary with the stimuli and the duration of stimulation. MAPK cascade induces Th differentiation and participates in T cell receptor signal pathway and B cell receptor signal pathway. MAPK cascades regulate various cellular activities related to the occurrence and development of cancer. A thorough and systematic understanding of the specific regulatory effects of MAPK cascade on various cellular processes will provide theoretical guidance for treating various diseases.

Application of single-cell sequencing technology in malignant tumor research / 中国肿瘤临床

Currently, malignant tumors are a major public health problem and pose a serious threat to human health. Because of the diversity and complexity and the high mortality rates, they have been a popular but complicated research topic for several years. Heterogeneity is one of the main characteristics of malignant tumors, and thus, this characteristic may affect many other aspects, such as tumorigenesis, development, metastasis, and therapeutic effects. With the completion of the Human Genome Project and the continuous advancement in sequencing technology, single-cell sequencing technology has been applied in many medical research fields; in particular, it is useful for analyzing tumor cell subpopulations, cell heterogeneity, tumor occurrence, evolution, and drug resistance. Therefore, this technology has provided us with a new tool for clinical diagnosis and treatment of malignant tumors and for estimating the prognosis at an early stage. In this article, we aimed to review the advances in single-cell sequencing technology and its application in malignant tumor research.

Correlation between blood glucose fluctuation and brain damage in neonates with hypoglycemia / 临床儿科杂志

Objective To explore the correlation between the fluctuation of blood glucose levels and brain damage in neonates with hypoglycemia. Methods The clinical data of 58 cases of neonatal hypoglycemia diagnosed from September 2013 to August 2016 were analyzed retrospectively. According to the results of neonatal cranial MRI and/or amplitude integrated electroencephalogram (aEEG), the neonates were divided into brain injury group and non-brain injury group. The fluctuation index of blood glucose was compared between two groups, and the correlation between the fluctuation of blood glucose level and brain injury was analyzed. Results In these 58 cases, 13 cases were in brain injury group (8 males and 5 females) and 45 cases were in non-brain injury group (27 males and 18 females). The lowest blood glucose (LBG) value in brain injury group was lower than that in non-brain injury group, while the duration of hypoglycemia, maximum blood glucose fluctuations (LAGE), standard deviation of blood glucose (SDBG), and average blood glucose fluctuations (MAGE) were higher than those in non-brain injury group, and they were all significantly different (P all<0.001). Conclusions Whether the hypoglycemia in newborn could lead to the brain injury or not depends not only on the minimum hypoglycaemia level and duration of hypoglycemia, but also on the indicators of glucose variation, such as LAGE, SDBG and MAGE.

Evaluation of CMS50F as a screening test for patients with obstructive sleep apnea hypopnea syndrome / 天津医药

Objective To evaluate the diagnostic accuracy of CMS50F for screening in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Sixty-four volunteers with suspected OSAHS underwent simultaneous noc?turnal polysomnography (PSG), micromovement sensitive mattress sleep monitoring system(MSMSMS)and CMS50F. The ap?nea-hypopnea index (AHI) detected by PSG and MSMSMS was used as the diagnostic standard for OSAHS. The reliability of CMS50F for monitoring sleep was assessed. Results There was no statistic difference in CMS50F-ODI3 and PSG-AHI be?tween normal, mild and moderate OSAHS groups(P>0.05). The CMS50F-ODI3 was smaller than the PSG-AHI in severe OSAHS patients(P 0.05). The value of CMS50F-ODI3 was smaller than MSMSMS-AHI in severe OSAHS patients (P < 0.05). There was also a significant correlation between CMS50F- ODI3 and MSMSMS-AHI (r=0.867,P <0.05). MSMSMS-AHI≥5 events per hour was used as the threshold value to diagnose OSAHS, the sensitivity and specificity of CMS50F were 94.5%and 88.9%. Conclusion CMS50F can be used as a portable and reliable device for screening of pa?tients suspected OSAHS.

Effect of berberine combined with bone marrow mesenchymal stem cells on energy metabolism of HUVECs damaged by high glucose / 中国药理学通报

Aim To investigate the effects of berberine combined with bone marrow mesenchymal stem cells ( BM-MSCs) on the energy metabolism of human um-bilical vein endothelial cells ( HUVECs ) under the condition of high glucose. Methods ①The state of cell reproduction and cell proliferating activity were de-termined by MTT assay. ②The cell cycle was detected by flow cytometry ( FCM ) . ③DNA damage of cells was measured by comet tail assay. ④The contents of ATP, ADP and AMP were determined by high perform-ance liquid chromatography ( HPLC ) and the level of energy charge ( EC) was calculated. ⑤The expression of CCR and COX mRNA was detected by reverse tran-scription-polymerase chain reaction ( RT-PCR) . ⑥The expressions of COX and CCR were detected by Western blot. Results ①The proliferating activity of HUVECs declined apparently and the proliferation decreased af-ter high glucose intervention. Meanwhile, the quantity of cells during S +G2 dropped dramatically and there was certain degree of damage to DNA. The berberine and BM-MSCs respectively improved the proliferating activity and the proliferation in different degrees, in-creased the quantity of cells during S+G2 and promo-ted the repair of DNA ( P <0 . 01 ) , and so did the combination of the two, with a better effect than each of them alone. ②After high glucose intervention and the damage caused, the content of both ATP and ADP of HUVECs was reduced, and EC level also declined significantly, while the content of AMP increased. The berberine and BM-MSCs respectively up-regulated the content of ATP and ADP ( P<0. 01 ) , and so did the combination of the two, with a better effect than each of them alone. ③After high glucose intervention and the damage caused, the expression of COX, CCR mR-NA and protein decreased obviously. Yet, all of the three gained a dramatic increase when the berberine, BM-MSCs or the combination of the two were added ( P<0. 01 or P <0. 05 ) , among which the combination worked more effectively. Conclusions The berber-ine, BM-MSCs and the joint use of the two could im-prove the energy metabolism of HUVECs, which had been damaged by high glucose, probably because the berberine and BM-MSCs could up-regulate the expres-sion of COX, CCR mRNA and protein, which leads to the hydrolyzation of glucose oxide and thus the im-provement of blood environment and the enhancement of glucose's supply and intake of HUVECs. Then, here comes the final result: the improvement of the energy metabolism of damaged vascular endothelial cells by high glucose.

Granulosa cells with stem cell properties in the rat ovary / 中国组织工程研究

BACKGROUND:Human and rat ovarian granulosa cels in dominant folicles have the phenomenon of expressing stem cel characteristics. OBJECTIVE:To investigate the expression of stem cel-related factors in rat ovarian granulosa cels. METHODS: After the paraffin sections of rat ovarian tissue, immunohistochemical method was used to detect CD34, CD133, ABCG2/Bcrp1, Pou5f1/Oct-4 expressions. Granulosa cels culturedin vitro were harvested by folicular puncture method, and then the immunohistochemical method was used to detect the expression of FSHR receptor in order to identify the purity of granule cels. In the cultured granulosa cels, CD44 and C-Kit expressions were detected immunohistochemicaly, RT-PCR was used to detect ABCG2/Bcrp1, Pou5f1/Oct-4, Nanog gene expressions in ovarian tissue and granulosa cels. RESULTS AND CONCLUSION:Immunohistochemistry detection on paraffin sections showed that a part of ovarian granulosa cels expressed CD34, CD133, ABCG2/Bcrp1 and Pou5f1/Oct-4, and the expression of Pou5f1/Oct-4 protein gradualy increased in the development of ovarian folicles, significantly enhanced during the luteal phase, and then disappeared after the formation of corpus albicans, displaying a periodic expression characteristics. FSHR receptor positive identification rate of primary cels harvested by the foliclar puncture method was more than 95%. Granulosa cels culturedin vitrowere mainly long spindle-shaped or diamond, and some cels presented with aggregation growth and expressed CD44 and C-Kit. RT-PCR test results showed that there were no Nanog in the ovarian tissue and cultured granulosa cels, low expression of Pou5f1/Oct-4 in the ovarian tissue, strong expression of ABCG2/Bcrp1 in the ovarian tissue, weak expression of Pou5f1/Oct-4 in the cultured granulosa cels, and strong expression of ABCG2/Bcrp1 in the cultured granulosa cels. These findings suggest that a part of granulosa cels in the rat ovarian have the characteristics of stem cels.

Construction of human telomerase reverse transcriptase-immortalized rat bone marrow mesenchemal stem cell strains / 中国组织工程研究

BACKGROUND:Because of convenient source, multi-lineage differentiation and low immunogenicity, bone marrow mesenchymal stem cels are the ideal cel type to serve as vectors of transgenic cels in pain management. However, the replicative senescence and smal amount of cels obtained from the bone marrow restrict the application of bone marrow mesenchymal stem cels in pain research. OBJECTIVE:To construct human telomerase reverse transcriptase (hTERT)-immortalized rat bone marrow mesenchymal stem cels as transgenic celular vectors for pain therapy. METHODS:Bone marrow mesenchymal stem cels were obtained from whole rat bone marrow, and then transfected with a lentivirus containing the hTERT (pLV-Puro-EF1α-hTERT) folowed by puromycin selection. hTERT expression and telomerase activity in these transfected cels were determined by RT-PCR and TRAP. Morphological changes, capacity of cel growth and multi-lineage differentiation, chromosome karyotype and tumorigenicity were observed in vitro. Moreover, the expression of cel surface molecule, Nestin, MHC-I and MHC-II in transfected cels were also detected by flow cytometry and immunocytochemistry. RESULTS AND CONCLUSION: The bone marrow mesenchymal stem cels geneticaly modified by hTERT could be cultured and passaged through 30 generations in vitro. Compared to the primary and negative transfected cels, the hTERT-modified bone marrow mesenchymal stem cels showed higher expression of hTERT mRNA, telomerase activity and cel proliferation. Most of transfected cels stayed at G2/M and S stages. The proliferation index of the transfected cels were increased dramaticaly. The positive rates of CD29, CD44 and CD90 were over 70%, but the positive rates of CD34 and CD45 were less than 5%. Transfected cels were positive for Nestin in the cytoplasm, but negative for MHC-1 and MHC-11. In addition, this cel line continued to exhibit the characteristics of fibroblastic bone marrow mesenchymal stem cels, including phenotype, differentiation into osteoblasts, adipocytes and neuron-like cels. No chromosome abnormality and tumor formation were observed in this experiment. Taken together, these data suggests that the rat bone marrow mesenchymal stem cels immortalized by hTERT gene are constructed successfuly and stil maintain major stem cels characteristics, which provide safe and stable cel vectors as research base for pain therapy.
