Making informed clinical decisions based on individualised outcome predictions is the cornerstone of precision psychiatry. Prediction models currently employed in psychiatry rely on algorithms that map a statistical relationship between clinical features (predictors/risk factors) and subsequent clinical outcomes. They rely on associations that overlook the underlying causal structures within the data, including the presence of latent variables, and the evolution of predictors and outcomes over time.

In this study, we explored the intricate relationship between Pannexin 1 (PANX1) and the Hippo signaling pathway effector, Yes-associated protein (YAP). Analysis of The Cancer Genome Atlas (TCGA) data revealed a significant positive correlation between PANX1 mRNA and core Hippo components, Yes-associated protein 1 [YAP], Transcriptional coactivator with PDZ-binding motif [TAZ], and Hippo scaffold, Ras GTPase-activating-like protein IQGAP1 [IQGAP1], in invasive cutaneous melanoma and breast carcinoma. Furthermore, we demonstrated that PANX1 expression is upregulated in invasive melanoma cell lines and is associated with increased YAP protein levels.

Pannexin 1 (PANX1) is upregulated in many cancers, where its activity and signalling promote tumorigenic properties. Here, we report a novel ∼25 kDa isoform of human PANX1 (hPANX1-25K) which lacks the N-terminus and was detected in several human cancer cell lines including melanoma, osteosarcoma, breast cancer and glioblastoma multiforme. This isoform was increased upon CRISPR/Cas9 deletion targeting the first exon near M1, suggesting a potential alternative translation initiation (ATI) site.

Importance: Military members and veterans (hereafter, veterans) with posttraumatic stress disorder (PTSD) increasingly seek psychiatric service dogs as a complementary intervention, yet the effectiveness of service dogs is understudied.

Objective: To estimate the associations between psychiatric service dog partnership and self-reported and clinician-rated PTSD symptom severity, depression, anxiety, and psychosocial functioning after 3 months of intervention among veterans.

Design, Setting, And Participants: This nonrandomized controlled trial used standardized and validated assessment instruments completed by participants and administered by blinded clinicians.
