How do information strategy and information technology governance influence firm performance?

Organizations today engage in turbulent competition to seize opportunities and cope with challenges by making strategy planning, increasing information technology (IT) investment, and other means. Based on survey data through questionnaires, this paper constructs models to explore the synergistic effects of information strategy (IS) and IT governance (ITG) on firm performance. The results show that, first, ITG and IS as explanatory variables have a significant influence on firm performance. Second, ITG has a positive effect on the relationship between IS and firm performance. This study extends existing research on IS and ITG by exploring the synergistic effects of IS and ITG on firm performance. The conclusion provides management insight and practical guidance for enterprises by actively implementing IS to improve firm performance to transform from the inherent pattern of traditional governance to the new technology governance.

MicroRNA-193b-3p reduces oxidative stress and mitochondrial damage in rats with cerebral ischemia-reperfusion injury via the seven in absentia homolog 1/Jun N-terminal kinase pathway.

Ischemic stroke is one of the major causes of death and disability among adults. This study sought to explore the mechanism of microRNA (miR)-193b-3p in rats with cerebral ischemia-reperfusion (I/R) injury. The cerebral I/R injury models of rats were established using the suture-occluded method. The pathological changes were observed, and oxidative stress (OS) and mitochondrial function indexes in rat brain tissue were examined. The levels of miR-193b-3p and seven in absentia homolog 1 (SIAH1) were detected. miR-193b-3p agomir or antagomir was injected into the lateral ventricle of I/R rats to overexpress or inhibit miR-193b-3p expression. The targeting relationship between miR-193b-3p and SIAH1 was verified. The effect of SIAH1 overexpression on brain injury in I/R rats was investigated by injecting the lentivirus vector into the lateral ventricle. The phosphorylation level of Jun N-terminal kinase (JNK) was identified. miR-193b-3p was lowly expressed in I/R rats. Overexpression of miR-193b-3p alleviated the pathological damage of I/R rats and limited the OS and mitochondrial damage. miR-193b-3p targeted SIAH1. Overexpression of SIAH1 partially reversed the protection of miR-193b-3p overexpression against cerebral I/R injury. p-JNK was up-regulated in I/R rats and overexpression of miR-193b-3p inhibited p-JNK. Overall, overexpression of miR-193b-3p targeted SIAH1 to inhibit the activation of the JNK pathway and protect rats against cerebral I/R injury.

MANCR drives esophageal carcinoma progression by targeting PDE4D.

PURPOSE: To explore the role of lncRNA MANCR in regulating in vitro proliferation and apoptosis in esophageal carcinoma cells and in vivo growth of esophageal carcinoma in nude mice. METHODS: MANCR levels in 15 pairs of esophageal carcinomas and non-tumoral tissues were detected by qRT-PCR. In vitro regulations of MANCR on proliferative and apoptotic potentials in TE-1 and EC-109 cells were explored by CCK-8, colony formation assay and flow cytometry. In addition, dual-luciferase reporter assay and rescue experiments were conducted to clarify the potential mechanisms of MANCR on regulating PDE4D. Finally, in vivo role of MANCR in mediating esophageal carcinoma growth was determined in nude mice implanted with EC-109 cells. RESULTS: MANCR was highly expressed in esophageal carcinomas tissues than non-tumoral ones. MANCR promoted proliferative ability and inhibited apoptosis in TE-1 and EC-109 cells. In nude mice with xenografted esophageal carcinoma, knockdown of MANCR markedly slowed down tumor growth. PDE4D was the target gene binding MANCR, which was downregulated in esophageal carcinoma tissues. Its level was negatively regulated by MANCR. Importantly, PDE4D could abolish the role of MANCR in stimulating the malignant progression of esophageal carcinoma. CONCLUSIONS: LncRNA MANCR is upregulated in esophageal carcinoma cases. Through negatively regulating PDE4D level, MANCR stimulates proliferative ability and inhibits apoptosis in esophageal carcinoma, thus driving the malignant progression.
