MED4 gene positively affects preadipocyte differentiation in Chinese red steppe cattle

Background:The regulatory genes related to lipid metabolism affect the intramuscular fat(IMF)content and improve meat quality traits.Mediator Complex Subunit 4(MED4),a vitamin D receptor protein,affects vitamin D,livestock growth,carcass traits,and triglyceride deposition.However,the physiological function of the MED4 gene on bovine adipocyte differentiation remains unknown.Methods:This study explored the function of the MED4 gene in preadipocyte differentiation in Chinese Red Steppe cattle.The overexpression plasmid and the interference sequences of the MED4 gene were constructed to detect the effects of the MED4 gene on adipogenesis and biomakers using quantitative polymerase chain reaction and western blotting.Results:The MED4 gene had significantly high expression during preadipocyte differentiation(p<0.05).Overexpression of the MED4 gene increased the expression of the PPARγgene,a preadipocyte differentiation biomarker,improved cellular lipid droplets and triglycerides accumulation,and positively accelerated adipocyte maturation(p<0.05).Interference of the MED4 gene can negatively regulate preadipocyte differentiation.Conclusion:This study showed that the MED4 gene may affect the preadipocyte differentiation and adipogenesis in Chinese Red Steppe cattle by regulating the PPARγgene.

A New Model for Correlation between the Marine Benthic Oxygen Isotope and Red Clay Magnetic Susceptibility on the Chinese Loess Plateau

Objective Aeolian sediments on the Chinese Loess Plateau contain some of the best continental archives of palaeoclimate change in the Late Cenozoic. The consensus that alternating MS in loess-paleosols in China was due to the strengthening and weakening of the East Asian palaeomonsoon provides an excellent climate record when correlated with global ice volume. Significantly, new basal dates from the red clay underlying the loess-paleosol sequence indicate that wind-blown dust began to accumulate on the Chinese Loess Plateau at least 22 million years ago. There are differences of opinion,

Approaches of Realizing Cultural Value of Red Revolutionary Site in Jiangxi Province:A Case Study of Chinese Workers' and Peasants' Red Army in Xiushui County

Red revolutionary site is a significant carrier for inheriting and spreading red culture,a witness of revolutionary history and stones,and also the best place to show connotations and value of red culture.Taking the regiment headquarter and the division headquarter of the First Division of the First Army in Xiushui County,Jiangxi Province for example,this paper explored cultural value of red site,analyzed the existing problems,tried to figure out scientific approaches of realizing cultural value of red site,so as to promote the sharing and inheritance of cultural value of red revolutionary site.

Red Chamber Charm Classic Chinese romance wows New York audience

Nobody would expect an American audience to understand a dance performance that tries to interpret one of China’s most revered, classic and complicated works of literature. They might, however, have been amazed at the enthusiastic response of the crowd at the Rose Theater at New York City’s Lincoln

Adjuvant Effects of Fermented Red Ginseng Extract on Advanced Non-Small Cell Lung Cancer Patients Treated with Chemotherapy

Objective： To investigate the adjuvant therapeutic effects of fermented red ginseng（FRG） extract on non-small cell lung cancer（NSCLC） patients treated with chemotherapy. Methods： A total of 60 patients with advanced NSCLC were assigned to two groups using a random number table, i.e., the gemcitabine plus cisplatin（GP） chemotherapy alone group（26 patients） and the FRG ＋ GP chemotherapy group（34 patients）, for 60-day treatment. Patients were then assessed according to the Fatigue Symptom Inventory, Chinese medicine symptoms score, Self-Rating Anxiety Scale, Self-Rating Depression Scale, Karnofsky Performance Status Scale, and Functional Assessment of Cancer Therapy-Lung. In addition, chemotherapy toxicity and tumor biomarkers were measured. Results： For NSCLC patients after chemotherapy, FRG extract significantly improved the FSI score, CM symptoms score, psychological status, physical conditions, and quality of life and reduced chemotherapy toxicity（P〈0.01）, but the expression levels of carcinoembryonic antigen, cytokeratin-19 fragments, and neuron-specific enolase were not significantly different between the chemotherapy alone and the FRG ＋ chemotherapy groups or between pre-and post-treatments（P〉0.05）. Conclusions： This study demonstrated that FRG extract had an adjuvant effect on advanced NSCLC patients treated with chemotherapy. Further studies with a larger sample size will verify the current findings.
