Profiling drug-protein interactions is critical for understanding a drug's mechanism of action and predicting the possible adverse side effects. However, to comprehensively profile drug-protein interactions remains a challenge. To address this issue, we proposed a strategy that integrates multiple mass spectrometry-based omics analysis to provided global drug-protein interactions, including physical interactions and functional interactions, with rapamycin (Rap) as a model.

The termination of employment is not the end of an organization-employee relationship. As ex-employees can provide various benefits to their former organizations, and a large number of ex-employees have accumulated in enterprises because of increased employee mobility, research on ex-employees' contribution behavior, and how it is generated are significant to organizations in making use of their ex-employees effectively and consequently improving organizational efficiency. Based on the research into organizational citizenship behavior, Study 1 extended the focus of organizational citizenship behavior research to include ex-employees, introducing the concept of ex-employee citizenship behavior.

Target identification is critically important for understanding the mechanism of action of drugs. Here, we reported a new strategy for deconvolution of drug targets (or off-targets) with photoaffinity labeling chemoproteomics in combination with untargeted metabolomics by using doxorubicin (DOX) as a model. The DOX-derived photoaffinity probes were prepared and applied to capture DOX-interacting proteins in living cells.

Article Synopsis
  • Port-wine stains (PWSs) are congenital disorders linked to various genetic mutations affecting blood vessel development, but the specific mutations remain largely unclear.
  • Researchers utilized whole-genome sequencing (WGS) on DNA from four patients to identify genetic variations, uncovering a known GNAQ mutation in one and six novel mutations across three genes in the others.
  • Additionally, two of the newly identified mutations showed frequencies of 60% and 40% in tests on five other sporadic PWS patients, emphasizing the genetic diversity in PWS and paving the way for potential clinical applications.

Boomerang employment has become an increasingly significant third way to obtain employees, yet little research has focused on why does ex-employee want to come back. Drawing from social identity theory, we propose that legacy identification could increase boomerang intention and both perceived corporate prestige and psychological contract violation could affect boomerang intention through legacy identification. The cooperative relationship between the former organization and the current organization could enhance these effects.

Negative feedback plays an important role in employee performance improvement, yet little research has specifically examined the motivational factor that drives employees to seek negative feedback. Drawing from the regulatory mode theory, we propose that assessment orientation could increase negative feedback-seeking by triggering individual self-criticism and participative leadership could enhance this effect. Results from a two-wave lagged survey study obtained from 216 Chinese employees suggested that assessment orientation is positively correlated with negative feedback-seeking via the mediating role of self-criticism.
