Circulating cell-free microRNAs (miRNAs) are stable in many biological fluids and their expression profiles can suffer changes under different physiological and pathological conditions. In the last few years, miRNAs have been proposed as putative noninvasive biomarkers in diagnosis, prognosis and response to treatment for several diseases, including(More)
Alzheimer's disease (AD) is a neurodegenerative disorder in which there is a decline of cholinergic function. The symptomatic AD treatment involves the use of ChEIs (cholinesterase inhibitors) as rivastigimine, a dual inhibitor. The human butyrylcholinesterase (BChE) is an enzyme that has specific roles in cholinergic neurotransmission and it has been(More)
Gene amplifications and deletions are common changes in human cancer cells. Previous studies indicate that the regions, where the ACHE (7q22) and BCHE (3q26.1-q26.2) genes are localized, are suffering such structural modifications in breast cancer. Therefore, the products of these genes, acetylcholinesterase and butyrylcholinesterase, respectively, are(More)
The human butyrylcholinesterase (BChE) is a serum esterase that has been associated with body mass index (BMI) and obesity. Its activity is conditioned by alleles of BCHE gene and the CHE2 locus that codifies an unknown BChE-binding protein (C5 complex). The hypothesis that the CHE2 locus is the RAPH1 gene, which encodes lamellipodin (Lpd), was raised in a(More)
Here, we report the first case of V180I rare mutation in a Brazilian woman whose clinical condition started with memory impairment for recent events and insomnia with 2 months of evolution, without any other alterations in neurological examination. Both the electroencephalogram (EEG) and the routine biochemical examination of cerebrospinal fluid (CSF) were(More)
Lamellipodin protein (Lpd), encoded by the RAPH1 gene, modulates the assembly of actin cytoskeleton through its binding to the Ena/VASPs proteins, and acts in cellular motility and lamelipodial protrusion. The region where RAPH1 gene is located (2q33) is deleted in various types of cancer and the gene expression changes in tumors when compared to normal(More)
Butyrylcholinesterase (BChE) is an enzyme encoded by BCHE gene, responsible for secondary hydrolysis of the acetylcholine. K and -116A BCHE variants were associated with decrease in plasma BChE activity, and their influence has been investigated in diseases with a cholinergic deficit such as Alzheimer's disease (AD) and dementia with Lewy bodies (DLB).
