Subclonal Complete Loss of CDKN1B as a Common Genomic Alteration in Prostate Cancer: Associations With Race and Prostate Cancer Outcomes. (PubMed, Mod Pathol) - "Overall, subclonal biallelic loss of CDKN1B resulting in complete p27 protein loss is one of the most commonly occurring biallelic tumor suppressor genomic alterations in primary prostate cancer, and could contribute to worse prostate cancer outcomes, specifically in AA individuals. Our findings warrant further exploration into the clinical utility of using IHC for p27 loss as a prognostic biomarker."

Early infliximab use is associated with less disease progression in luminal crohn's disease: a real-world tertiary centre experience (BSG 2025) - "However, in patients with luminal inflammatory CD who started therapy within 2 years of disease onset there was less disease progression, defined as extension in location, behaviour or new perianal disease (2/52 vs 10/65 chi sq 4.18 p=0.04) and a trend towards less systemic steroid use (4/52 vs 13/65 chi sq 3.53 p=0.06).Download figure Open in new tab Download powerpoint Abstract P275 Figure 1 Persistence on therapy, surgery and hospitalisation free survival, categorised by duration from diagnosis until first infliximab dose*luminal = Montreal B1P0Conclusions Early infliximab therapy is associated with less disease progression and less use of systemic steroids. The lack of variation in other outcomes may be due to historical case selection for advanced therapies."

Specific Conformational Dynamics and Expansion Underpin a Multi-Step Mechanism for Specific Binding of p27 with Cdk2/Cyclin A. (PubMed, J Mol Biol) - "In summary, the binding interaction involves three steps: i) D1 initiates binding, ii) p27 wraps around Cdk2/Cyclin A and D2 binds, and iii) the fully-formed fuzzy ternary complex is formed concomitantly with extension of the post-KID region. An understanding of how the IDP nature of p27 underpins its functional interactions with Cdk2/Cyclin A provides insight into the complex binding mechanisms of IDPs and their regulatory mechanisms."
