Current models of aggression suggest that in addition to personality traits and environmental factors, biological vulnerability associated with genetics substantially impacts aggressive behavior. In a functional imaging study, we investigated the influence of the single nucleotide polymorphism of the mu 1 subtype opioid receptor gene (OPRM1), implicated in sociability, on correlates of trait and state aggression to delineate the function of these influences in aggression. A key aim was further to differentiate different aspects of aggressive reactions - namely, the reaction to provocation and the decision to punish an opponent. Read More

The PPP1R1B gene is located on chromosome 17q12 (39,626,208-39,636,626[GRCh38/hg38]), which codes for multiple transcripts and two experimentally-documented proteins Darpp-32 and t-Darpp. Darpp-32 (Dopamine and cAMP Regulated Phosphoprotein), discovered in the early 1980s, is a protein whose phosphorylation is upregulated in response to cAMP in dopamine-responsive tissues in the brain. It's phosphorylation profile modulates its ability to bind and inhibit Protein Phosphatase 1 activity, which, in turn, controls the activity of hundreds of phosphorylated proteins. Read More

NUTM1-rearranged tumors are defined by the presence of a gene fusion between NUTM1 and various gene partners, and typically follow a clinically aggressive disease course with poor outcomes despite conventional multi-modality therapy. NUTM1-rearranged tumors display histologic features of a poorly differentiated carcinoma with areas of focal squamous differentiation and typically express the NUTM1-BRD4 fusion gene defining a distinct clinico-pathologic entity - NUT carcinoma (NC). NC with mesenchymal differentiation have rarely been described in the literature. Read More

Serrated adenocarcinoma, an alternative pathway for colorectal cancer (CRC) development, accounts for 15%-30% of all CRCs and is aggressive and treatment resistant. We show that the expression of atypical protein kinase C ζ (PKCζ) and PKCλ/ι was reduced in human serrated tumors. Simultaneous inactivation of the encoding genes in the mouse intestinal epithelium resulted in spontaneous serrated tumorigenesis that progressed to advanced cancer with a strongly reactive and immunosuppressive stroma.

For species that form dominance hierarchies, such as group-living ungulates, aggressive interactions can pose a challenge to successful captive management. For example, Jackson's hartebeest (Alcelaphus buselaphus), a rare antelope of east Africa, can be difficult to maintain in captivity because aggression within female dominance hierarchies can lead to injury and death. We quantified behavioral and endocrine correlates of dominance in a captive herd of ten female hartebeest with the goal of understanding how to minimize dangerous interactions. Read More
