GRIN3A: A biomarker associated with a cribriform pattern and poor prognosis in prostate cancer.

Prostate cancer with a cribriform pattern, including invasive cribriform carcinoma (ICC) and/or intraductal carcinoma (IDC) is associated with a poor prognosis, and the underlying mechanisms are unclear. Therefore, we aimed to identify biomarkers for this feature. Using a radical prostatectomy cohort, we performed within-patient differential expression analyses with RNA sequencing data to compare samples with a cribriform pattern to those with non-cribriform Gleason pattern 4 (NcGP4; n=13).

Prostate cancer: Molecular aspects, consequences, and opportunities of the multifocal nature.

Prostate cancer is unique compared to other major cancers due to the presence of multiple primary malignant foci in the majority of patients at the time of diagnosis. Each malignant focus has distinct somatic mutations and gene expression patterns, which represents a challenge for the development of prognostic tests for localized prostate cancer. Additionally, the molecular heterogeneity of advanced prostate cancer has important implications for management, particularly for patients with metastatic and locally recurrent cancer.

Contribution of SARS-CoV-2 infection preceding COVID-19 mRNA vaccination to generation of cellular and humoral immune responses in children.

Primary COVID-19 vaccination for children, 5-17 years of age, was offered in the Netherlands at a time when a substantial part of this population had already experienced a SARS-CoV-2 infection. While vaccination has been shown effective, underlying immune responses have not been extensively studied. We studied immune responsiveness to one and/or two doses of primary BNT162b2 mRNA vaccination and compared the humoral and cellular immune response in children with and without a preceding infection.

Changing colors and understanding: the use of mutant chromogenic protein and informational suppressor strains of to explore the central dogma of molecular biology.

The central dogma of molecular biology is a key concept for undergraduate students in the life sciences as it describes the flow of information in living systems from gene-to-gene product. However, despite often being covered in many introductory life science courses, students may still have misconceptions surrounding the central dogma even as they move on to advanced courses. Active learning strategies such as laboratory activities can be useful in addressing such misconceptions.
