Four researchers from UCLA’s Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have received Early Translational Research Awards totaling approximately $13 million from the California Institute for Regenerative Medicine, the state's stem cell agency. The UCLA researchers received four of the 12 total awards; no other institution received more than one.
The Independent Citizens Oversight Committee, CIRM’s governing body, announced at its Aug. 28 meeting in La Jolla, Calif., that grant recipients included Dr. Jerome Zack, professor of medicine and microbiology, immunology and molecular genetics; Dr. Robert Reiter, Bing Professor of Urologic Research; Dr. Donald Kohn, professor of pediatrics and microbiology, immunology and molecular genetics in th...

Abstract
Few options are available for treating patients with advanced prostate cancer (PC). As PC is a slow growing disease and accessible by ultrasound, gene therapy could provide a viable option for this neoplasm. Conditionally replication?competent adenoviruses (CRCAs) represent potentially useful reagents for treating prostate cancer (PC). We previously constructed a CRCA, Cancer Terminator Virus (CTV), which showed efficacy both in vitro and in vivo for PC. The CTV was generated on a serotype 5?background (Ad.5?CTV) with infectivity depending on Coxsackie?Adenovirus Receptors (CARs). CARs are frequently reduced in many tumor types, including PCs thereby limiting effective Ad?mediated therapy. Using serotype chimerism, a novel CTV (Ad.5/3?CTV) was created by replacing the ...

'Grinder' can listen to music player by wearing a loose wire coil around his neckDon't offer Rich Lee a pair of headphones to listen to music: he's already got a pair, even though you can't see them. They're implanted in his ears – a procedure carried out by a "body modification" expert.Now, by connecting his music player to a loose wire coil around his neck (which he can tuck under his shirt), Lee can listen to music without blocking out the outside world. The tiny magnets implanted invisibly in his outer ears pick up the signal and generate sound.But that's only the beginning. Lee, 34, who works as a salesman, intends to hook it up to an ultrasonic rangefinder – effectively giving himself bat-like echolocation. And he would like to have X-ray vision, super-strength, and anything else...

Abstract
Hepatitis C virus (HCV) is a hepatotropic member of the Flaviviridae family and contains a 9.6 kb positive-sense RNA genome. Approximately 170-million people are infected with HCV worldwide. These people face increased risks of chronic hepatitis, cirrhosis and hepatocellular carcinoma compared with the general population. Transduction of the HCV genome into hepatocytes is essential for understanding the mode of action of HCV infection, and for preparing HCV, evaluating HCV replication, and screening anti-HCV drugs. Although electroporation of in vitro-synthesized HCV genome and transduction of plasmid vectors containing the HCV genome are widely used in HCV research, a more convenient system with higher transduction efficie...

Muscle stiffness is a major clinical feature in Duchenne muscular dystrophy (DMD). DMD is the most common lethal inherited muscle-wasting disease in boys, and it is caused by the lack of the dystrophin protein. We recently showed that the extensor digitorum longus (EDL) muscle of mdx mice (a DMD mouse model) exhibits disease-associated muscle stiffness. Truncated micro- and mini-dystrophins are the leading candidates for DMD gene therapy. Unfortunately, it has never been clear whether these truncated genes can mitigate muscle stiffness. To address this question, we examined the passive properties of the EDL muscle in transgenic mdx mice that expressed a representative mini- or micro-gene (H2-R15, R2-15/R18-23/C, or R4-23/C). The passive properties were measured at the ages of 6 and 20 mo a...

Potent growth-inhibitory effect of a dual cancer-specific oncolytic adenovirus expressing apoptin on prostate carcinoma.
Int J Oncol. 2013 Mar;42(3):1052-60
Authors: Zhang M, Wang J, Li C, Hu N, Wang K, Ji H, He D, Quan C, Li X, Jin N, Li Y
Abstract
Apoptin is a chicken anemia virus-derived, p53-independent, bcl-2-insensitive apoptotic protein with the ability to specifically induce apoptosis in various human tumor cells, but not in normal cells. To explore the use of apoptin in tumor gene therapy, we assessed a recombinant adenovirus expressing the apoptin protein (Ad-hTERTp-E1a-Apoptin) in order to determine its lethal and growth-inhibitory effects on PC-3 and RM-1 cells in vitro and its antitumor effect on solid tumors in vivo....

Abstract
In this experiment, we developed anionic ternary complexes for effective and safe ocular gene delivery. Ternary complexes were constructed by coating plasmid DNA (pDNA)/polyethylenimine (PEI) complex with anionic polymers such as ?-polyglutamic acid (?-PGA) and chondroitin sulfate (CS). The cationic pDNA/PEI complex showed high gene expression on the human retinal pigment epithelial cell line, ARPE-19 cells. The pDNA/PEI complexes, however, also showed high cytotoxicity on the cells and aggregated strongly in the vitreous body. On the other hand, the anionic ternary complexes showed high gene expression on ARPE-19 cells without such cytotoxicity and aggregation. Afte...

Research on human beings has expanded greatly due to progress and the evolution of society as well as customs. Not only the unceasing development of research on human beings, but also interference in the beginning and end of life with homologous and heterogonous human reproduction, surrogate motherhood, cloning, gene therapies, eugenics,euthanasia, dysthanasia, orthothanasia, assisted suicide, genetic engineering, reassignment surgery in cases of transsexuality, the use of recombinant DNA technology and embryonic stem cells, transplantation of human organs and tissues, biotechnology and many other scientific advances. Scientific progress goes faster than the real needs of human beings, who are the final recipient of the entire evolutionary progress. Hence, there is the need to scrutinize w...

After the first description of a patient recognized as a MPS case was made in 1917, several similar cases were described and identified. Observations reported in the middle of the twentieth century concerning the presence of acid mucopolysaccharides (later called glycosaminoglycans, or GAGs) in tissues and especially in urine of patients were instrumental in providing an identity for these diseases, which became referred as "mucopolysaccharidoses" (MPS). In the late 1960's it was demonstrated that MPS were caused by defects in the breakdown of GAGs, and the specific enzyme deficiencies for the 11 types and subtypes of MPS were identified thereafter. Genes involved in the MPS were subsequently identified, and a large number of disease-causing mutations were identified in each one. Although ...

In this study, we sought to examine whether this attribute could be exploited in cancer suicide gene therapy by using a lentiviral (LV) vector expressing herpes simplex virus thymidine kinase (HSV-TK/GCV) under the regulation of antioxidant response element (ARE), a cis-acting enhancer sequence that binds Nrf2. In human lung adenocarcinoma cells in which Nrf2 is constitutively overexpressed, ARE activity was found to be high under basal conditions. In this setting, ARE-HSV-TK was more effective than a vector in which HSV-TK expression was driven by a constitutively active promoter. In a mouse xenograft model of lung cancer, suicide gene therapy with LV-ARE-TK/GCV was effective compared with LV-PGK-TK/GCV in reducing tumor size. We conclude that ARE-regulated HSV-TK/GCV therapy offers a pro...

MicroRNAs are short non-coding RNAs that can regulate gene expression in cancer development, which makes them valuable targets for therapeutic intervention. Here we report on an approach that can not only arrest the functions of mature miRNAs by binding to them but it can also induce the “mis-processing” of the target miRNA producing a non-functional truncated miRNA. This approach involves generating an expression construct that produces a RNA fragment with sixteen repeat sequences. The construct is named miR-Pirate or microRNA-interacting RNA—producing imperfect RNA and tangling endogenous miRNA. The transcript of the construct contained mismatches to the seed region, and thus it would not target the potential targets of the miRNA under study. The homology of the cons...
