Incorporating art into a biology course: a student-curated art exhibition about COVID-19.

Incorporating art into science, technology, engineering, and mathematics (STEM) courses can be an effective way to help students understand scientific concepts and think about those concepts more holistically. Additionally, art can be used to inform the public about scientific issues. To explore this topic more fully, we developed an assignment for an upper-level biology course in which students curated an art exhibition focused on the 2019 coronavirus disease, COVID-19. Working in pairs, students identified pieces of art in the College's permanent collection that they felt related to some aspect of the pandemic. Each pair wrote a short curator's statement and a more traditional academic essay. The works of art and the curator's statements were displayed on campus. Visitors to the exhibition were invited to complete a short survey about the exhibition and its relevance to COVID-19. Anecdotal evidence suggests that the students enjoyed and valued the assignment. Limited data from visitors to the exhibition show that they thought the art helped them think more deeply about the pandemic. Based on these results, we conclude that the development of art exhibitions in STEM courses can benefit the students and the public.

The role of PKC and PKD in CXCL12 and CXCL13 directed malignant melanoma and acute monocytic leukemic cancer cell migration.

Cancer metastasis is the leading cause of cancer related mortality. Chemokine receptors and proteins in their downstream signalling axis represent desirable therapeutic targets for the prevention of metastasis. Despite this, current therapeutics have experienced limited success in clinical trials due to a lack of insight into the downstream signalling pathway of specific chemokine receptor cascades in different tumours. In this study, we investigated the role of protein kinase C (PKC) and protein kinase D (PKD) in CXCL12 and CXCL13 stimulated SK-MEL-28 (malignant melanoma) and THP-1 (acute monocytic leukaemia) cell migration. While PKC and PKD had no active role in CXCL12 or CXCL13 stimulated THP-1 cell migration, PKC and PKD inhibition reduced CXCL12 stimulated migration and caused profound effects upon the cytoskeleton of SK-MEL-28 cells. Furthermore, only PKC and not PKD inhibition reduced CXCL13 stimulated migration in SK-MEL-28 cells however PKC inhibition failed to stimulate any changes to the actin cytoskeleton. These findings indicate that PKC inhibitors would be a useful therapeutic for the prevention of both CXCL12 and CXCL13 stimulated migration and PKD inhibitors for CXCL12 stimulated migration in malignant melanoma.
