Abstract

MCM10 plays a vital role in genome duplication and is crucial for DNA replication initiation, elongation, and termination. It coordinates several proteins to assemble at the fork, form a functional replisome, trigger origin unwinding, and stabilize the replication bubble. MCM10 overexpression is associated with increased aggressiveness in breast, cervical, and several other cancers. Disruption of MCM10 leads to altered replication timing associated with initiation site gains and losses accompanied by genome instability. Knockdown of MCM10 affects the proliferation and migration of cancer cells, manifested by DNA damage and replication fork arrest, and has recently been shown to be associated with clinical conditions like CNKD and RCM. Loss of MCM10 function is associated with impaired telomerase activity, leading to the accumulation of abnormal replication forks and compromised telomere length. MCM10 interacts with histones, aids in nucleosome assembly, binds BRCA2 to maintain genome integrity during DNA damage, prevents lesion skipping, and inhibits PRIMPOL-mediated repriming. It also interacts with the fork reversal enzyme SMARCAL1 and inhibits fork regression. Additionally, MCM10 undergoes several post-translational modifications and contributes to transcriptional silencing by interacting with the SIR proteins. This review explores the mechanism associated with MCM10’s multifaceted role in DNA replication initiation, chromatin organization, transcriptional silencing, replication stress, fork stability, telomere length maintenance, and DNA damage response. Finally, we discuss the role of MCM10 in the early detection of cancer, its prognostic significance, and its potential use in therapeutics for cancer treatment.

Polypen bei nahen Verwandten – erhöhtes Darmkrebsrisiko

Werden bei erstgradigen Verwandten gutartige Darmpolypen identifiziert, ist das Risiko, selbst an einem Kolorektalkarzinom zu erkranken, deutlich erhöht – vor allem das für eine früh beginnende Erkrankung. Hier könnte sich eine frühe Koloskopie besonders lohnen.

KI-gestütztes Mammografiescreening überzeugt im Praxistest

Mit dem Einsatz künstlicher Intelligenz lässt sich die Detektionsrate im Mammografiescreening offenbar deutlich steigern. Mehr unnötige Zusatzuntersuchungen sind laut der Studie aus Deutschland nicht zu befürchten.

Welche Krebserkrankungen bei Zöliakie häufiger auftreten

Eine große Kohortenstudie hat den Zusammenhang zwischen Zöliakie und gastrointestinalen Krebserkrankungen und inflammatorischen Krankheiten untersucht. Neben gastrointestinalen Tumoren ist auch ein nicht solider Krebs häufiger.

Adjuvanter PD-L1-Hemmer verhindert Rezidive bei Hochrisiko-Urothelkarzinom

Sind Menschen mit muskelinvasivem Urothelkarzinom für die neoadjuvante platinbasierte Therapie nicht geeignet oder sprechen sie darauf nicht gut an, ist Pembrolizumab eine adjuvante Alternative: Die krankheitsfreie Lebenszeit wird dadurch mehr als verdoppelt.
