Novel method of paraffin embedding cultured cells and organoids using silicone molds.

A major issue facing the field of cellular imaging, immunofluorescence (IF), and immunohistochemistry (IHC) microscopy is antibody quality. One of the main methods of antibody validation is testing on positive and negative control tissues with known expression levels of a given antigen. However, this approach is reliant on availability of tissues and reliable protein expression datasets, which are not always available.

Multispectral Imaging of Intrinsic Metabolic Fluorophores: Detection of Human Breast Cancer in Fresh Ex Vivo Specimens.

A growing number of women develop breast cancer and require surgery. Many lumpectomies lead to follow-up procedures after the initial surgery. Advanced scanning technologies have reduced the number of second and third surgeries, but only by about 50%.

OLIG2 mediates a rare targetable stem cell fate transition in sonic hedgehog medulloblastoma.

Functional cellular heterogeneity in tumours often underlies incomplete response to therapy and relapse. Previously, we demonstrated that the growth of the paediatric brain malignancy, sonic hedgehog subgroup medulloblastoma, is rooted in a dysregulated developmental hierarchy, the apex of which is defined by characteristically quiescent SOX2 stem-like cells. Integrating gene expression and chromatin accessibility patterns in distinct cellular compartments, we identify the transcription factor Olig2 as regulating the stem cell fate transition from quiescence to activation, driving the generation of downstream neoplastic progenitors.

Suppressing recurrence in Sonic Hedgehog subgroup medulloblastoma using the OLIG2 inhibitor CT-179.

OLIG2-expressing tumor stem cells have been shown to drive recurrence in Sonic Hedgehog (SHH)-subgroup medulloblastoma (MB) and patients urgently need specific therapies to target this tumor cell population. Here, we investigate the therapeutic potential of the brain-penetrant orally bioavailable, OLIG2 inhibitor CT-179, using SHH-MB explant organoids, PDX and GEM SHH-MB models. We find that CT-179 disrupts OLIG2 dimerization, phosphorylation and DNA binding and alters tumor cell-cycle kinetics, increasing differentiation and apoptosis.

The talk and walk in Black families: Exploring racial socialization content and competency in the context of parental worries about racial profiling and adolescents' internalizing outcomes.

Although many parents worry that their child will be the target of racial profiling, there is a dearth of literature on how parental worries about children facing racism are linked to racial socialization (RS) practices and youth internalizing symptoms. Additionally, it is unclear how RS content relative to competency may uniquely influence whether and how parental worries influence youth internalizing outcomes. Using data from 203 Black parents (M = 44.
