RESUMO
Little is known about how insecure attachment affects aggressive behavior and well-being among Vietnamese youth. Using structural equation modeling, we investigate the mediating role of subjective social status (SSS) on the paths from insecure attachment to overt aggressive behavior (OAB) and psychological well-being (PW) in a sample of 1753 Vietnamese adolescents (Mage = 16.136, SD = 0.784) and test whether the results will be replicated in another sample of 601 Vietnamese young adults (Mage = 19.93, SD = 1.35). Participants complete a survey comprising demographic information, attachment styles, SSS, OAB, and PW questionnaires. Our main findings include: (a) anxious attachment positively related to OAB in both samples, (b) anxious attachment was only negatively associated with adolescents' PW, (c) avoidant attachment was positively correlated to OAB in adolescents but negatively correlated in young adults, and (d) avoidant attachment was negatively related to PW in both samples. In addition, (e) in adolescents, the mediation role of SSS was significant in all paths, but (f) SSS only mediated the link from avoidant attachment to PW of young adults. The present study suggests that aggressive behavior might not be associated with social status or attachment in the same way in adolescents compared to young adult Vietnamese samples.
RESUMO
Current approaches to define chemical-genetic interactions (CGIs) in human cell lines are resource-intensive. We designed a scalable chemical-genetic screening platform by generating a DNA damage response (DDR)-focused custom sgRNA library targeting 1011 genes with 3033 sgRNAs. We performed five proof-of-principle compound screens and found that the compounds' known modes-of-action (MoA) were enriched among the compounds' CGIs. These scalable screens recapitulated expected CGIs at a comparable signal-to-noise ratio (SNR) relative to genome-wide screens. Furthermore, time-resolved CGIs, captured by sequencing screens at various time points, suggested an unexpected, late interstrand-crosslinking (ICL) repair pathway response to camptothecin-induced DNA damage. Our approach can facilitate screening compounds at scale with 20-fold fewer resources than commonly used genome-wide libraries and produce biologically informative CGI profiles.
