Recent genome-wide association studies indicate that a simple alteration of Leucine-rich repeat kinase 2 (LRRK2) gene expression may contribute to the etiology of sporadic Parkinson's disease (PD). However, the expression and regulation of LRRK2 protein in the sporadic PD brains remain to be determined. Here, we found that the expression of LRRK2 protein was enhanced in the sporadic PD patients...
Induction of the Arf tumor suppressor (encoded by the alternate reading frame of the Cdkn2a locus) following oncogene activation engages a p53-dependent transcriptional program that limits the expansion of incipient cancer cells. Although the p19(Arf) protein is not detected in most tissues of fetal or young adult mice, it is physiologically expressed in the fetal yolk sac, a tissue derived fro...
Although various pharmacological activities of the shikonins have been documented, understanding the hierarchical regulation of these diverse bioactivities at the genome level is unsubstantiated. In this study, through cross examination between transcriptome and microRNA array analyses, we predicted that topical treatment of shikonin in vivo affects epithelial-mesenchymal transition (EMT) and t...
Esophageal squamous cell carcinoma (ESCC) is a leading cause of cancer-related deaths worldwide. The high mortality of ESCC is mainly due to late diagnosis. Current detection methods have their own weakness, including high costs and invasive procedures. MicroRNA assays are shown to have great potential to be accurate and noninvasive methods for ESCC screening. In this study, we selected 3 micro...
The majority of non-small cell lung cancer (NSCLC) patients harbor EGFR-activating mutations that can be therapeutically targeted by EGFR tyrosine kinase inhibitors (EGFR-TKI), such as erlotinib and gefitinib. Unfortunately, a subset of patients with EGFR mutations are refractory to EGFR-TKIs. Resistance to EGFR inhibitors reportedly involves SRC activation and induction of epithelial-to-mesenc...
سابقه و هدف: یکی از راه های کنترل فرایند خون سازی, تنظیم به وسیله microrna های مختلف می باشد. این rnaهای کوچک تنظیم کننده با تغییر در بیان ژن ها در مرحله پس از رونویسی, توانایی کنترل مراحل مختلف خون سازی را دارا می باشند. درمان بیماری های مختلف با استفاده از سلول های +cd-133 که از خون بند ناف جدا شده و در محیط آزمایش گاه تکثیر یافته اند در حال گسترش می باشد. هدف این مطالعه بررسی تغییرات ایجاد ش...
