Germline sequencing in men with metastatic castration-resistant prostate cancer from the BARCODE2 study reveals a wide range of pathogenic variants in DNA repair genes.

Background: The presence of germline mutations plays an increasingly important role in risk assessment and treatment of prostate cancer (PrCa). Screening for high-risk mutations in subsets of patients is becoming routine. We explore the prevalence of germline genetic mutations in men with metastatic castration-resistant prostate cancer (mCRPC) recruited to the BARCODE2 trial.

How can we recruit more men of African or African-Caribbean ancestry into our research? Co-creating a video to raise awareness of prostate cancer risk and the PROFILE study.

Background: Men of African ancestry are at increased risk of developing prostate cancer (PrCa) compared to men from other backgrounds. The PROFILE study aims to understand whether genetic information can better target who needs PrCa screening. PROFILE has so far had difficulty reaching men of African or African -Caribbean ancestry to take part.

Prostate cancer risk in men of differing genetic ancestry and approaches to disease screening and management in these groups.

Prostate cancer is the second most common solid tumour in men worldwide and it is also the most common cancer affecting men of African descent. Prostate cancer incidence and mortality vary across regions and populations. Some of this is explained by a large heritable component of this disease.

The BARCODE1 Pilot: a feasibility study of using germline single nucleotide polymorphisms to target prostate cancer screening.

Objectives: To assess the feasibility and uptake of a community-based prostate cancer (PCa) screening programme selecting men according to their genetic risk of PCa. To assess the uptake of PCa screening investigations by men invited for screening. The uptake of the pilot study would guide the opening of the larger BARCODE1 study recruiting 5000 men.

A synergistic interaction between lapatinib and chemotherapy agents in a panel of cell lines is due to the inhibition of the efflux pump BCRP.

Lapatinib is a specific HER1 and 2 targeted tyrosine kinase inhibitor now widely used in combination with chemotherapy in the clinical setting. In this work, we investigated the interactions between lapatinib and specific chemotherapy agents (cisplatin, SN-38, topotecan) in a panel of cell lines [breast (n = 2), lung (n = 2), testis (n = 4)]. A high-sensitivity cell proliferation/cytotoxicity ATP assay and flow cytometry were used to determine cell viability, apoptosis, and the effect of the drugs on cell-cycle distribution.

The relative activity of cisplatin, oxaliplatin and satraplatin in testicular germ cell tumour sensitive and resistant cell lines.

Background: Germ cell tumours (GCT) can become resistant to cisplatin, which is associated with a relatively poor prognosis. Oxaliplatin and satraplatin have been developed to overcome cisplatin resistance in other cancers, but their effect in cisplatin resistant (cisR) GCTs is unclear. In this work we address this issue by comparing their efficacy in three paired sensitive and cisR GCT cell lines.
