Genome-Wide Epigenomic Analyses in Patients With Nociceptive and Neuropathic Chronic Pain Subtypes Reveals Alterations in Methylation of Genes Involved in the Neuro-Musculoskeletal System
Published: September, 2021
Abstract: Nociceptive pain involves the activation of nociceptors without damage to the nervous system, whereas neuropathic pain is related to an alteration in the central or peripheral nervous system. Chronic pain itself and the transition from acute to ch...

Muscle allele-specific expression QTLs may affect meat quality traitsin Bos indicus.
Published: April, 2021
Abstract: Single nucleotide polymorphisms (SNPs) located in transcript sequences showing allele-specific expression (ASE SNPs) were previously identified in the Longissimus thoracis muscle of a Nelore (Bos indicus) population consisting of 190 steers. Given...

Developmental cannabidiol exposure increases anxiety and modifiesgenome-wide brain DNA methylation in adult female mice.
Published: January, 2021
Abstract: BACKGROUND: Use of cannabidiol (CBD), the primary non-psychoactive compound found in cannabis, has recently risen dramatically, while relatively little is known about the underlying molecular mechanisms of its effects. Previous work indicates that...

IGFBP2 protects against pulmonary fibrosis through inhibiting P21-mediated senescence
Published: January, 2021
Abstract: Accumulation of senescent cells contributes to age related diseases including idiopathic pulmonary fibrosis (IPF). Insulin-like growth factor binding proteins (IGFBPs) are evolutionarily conserved proteins that play a vital role in many biological...
