Μελέτες διασταυρούμενης μετάβασης (cross over studies)

open access: yes, 2010
Η πλειοψηφία των μελετών που χρησιμοποιούνται στις μετα-αναλύσεις είναι τυχαιοποιημένες δοκιμές παράλληλων ομάδων. Υπάρχει όμως και μια άλλη κατηγορία τυχαιοποιημένων μελετών που είναι οι μελέτες διασταυρούμενης μετάβασης. Για τις μελέτες αυτές που παρουσιάζουν ιδιαιτερότητες, τόσο μεθοδολογικές όσο και στατιστικής ανάλυσης, δεν υπάρχει καθιερωμένη ...

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Screening for lung cancer: A systematic review of overdiagnosis and its implications

open access: yesMolecular Oncology, EarlyView.
Low‐dose computed tomography (CT) screening for lung cancer may increase overdiagnosis compared to no screening, though the risk is likely low versus chest X‐ray. Our review of 8 trials (84 660 participants) shows added costs. Further research with strict adherence to modern nodule management strategies may help determine the extent to which ...

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

open access: yesMolecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.
