Most squamous cell carcinomas of the head and neck (HNSCC) exhibit a persistent activation of the PI3K-mTOR signaling pathway. We have recently shown that metformin, an oral antidiabetic drug that is also used to treat lipodystrophy in HIV-infected (HIV(+)) individuals, diminishes mTOR activity and prevents the progression of chemically induced experimental(More)
Presenilins (PS1 and PS2) are supposed to be unusual aspartic proteases and components of the gamma-secretase complex regulating cleavage of type I proteins. Multiple mutations in PS1 are a major cause of familial early-onset Alzheimer's disease (AD). We and others recently identified PS-related families of proteins (IMPAS/PSH/signal peptide peptidases(More)
The Human Genome Project stimulated the development of efficient strategies and relevant hardware for complete genome sequencing. The comparative genomic approach extends the possibilities of using the sequencing data to identify new genes or conserved regulatory regions by means of nucleotide sequence alignment of the particular regions of the mouse and(More)
