Transcriptional profiling coupled with blood metabolite analyses were used to identify porcine genes and pathways that respond to a fasting treatment or to a D298N missense mutation in the melanocortin-4 receptor (MC4R) gene. Gilts (12 homozygous for D298 and 12 homozygous for N298) were either fed ad libitum or fasted for 3 days. Fasting decreased body weight, backfat, and serum urea concentration and increased serum nonesterified fatty acid. In response to fasting, 7,029 genes in fat and 1,831 genes in liver were differentially expressed (DE). MC4R genotype did not significantly affect gene expression, body weight, backfat depth, or any measured …

Gene Therapy For Amyotrophic Lateral Sclerosis: An Aav Mediated Rnai Approach For Autosomal Dominant C9orf72 Associated Als, Gabriela Toro

Amyotrophic lateral sclerosis (ALS) is a terminal neurodegenerative disease that affects motor neurons causing progressive muscle weakness and respiratory failure. In 2011, the presence of a hexanucleotide repeat expansion within chromosome 9 open reading frame 72(C9ORF72) was identified in ALS patient samples, becoming the major known genetic cause for ALS and frontotemporal dementia (FTD). Carriers of this mutation present reduced levels of C9ORF72 mRNA, RNA foci produced by the aggregating expansion and toxic dipeptides generated through repeat-associated non-ATG translation. These findings have led to multiple hypotheses on the pathogenesis of C9ORF72: 1) Haploinsufficiency, 2) RNA gain-of-function, 3) RAN …
