Struggling for breath: the ongoing decline of the right-wing press
I have lost countless hours of my life to football management simulation games. The artificial reality wherein you pit yourself against the tactical genius of Jose Mourinho and Jurgen Klopp whilst splashing millions with wanton caprice on some grossly overrated midfield primadonna I find, for some unexplained reason, compelling. Every so often however, a game goes awry. Despite playing a tiki-taca style which would envy even Josep Guardiola, you face the ignominy of losing 1-0 to Shrewsbury Town
Survivin phosphorylation and M-phase promoting factor in oral carcinogenesis
Survivin is a recently described inhibitor of
apoptosis and mitotic regulator which is selectively overexpressed
in human tumors. Its expression rate is
predictive of disease progression, early recurrences and
resistance to therapy. Up-regulation of survivin in oral
pre-malignant lesions (OPL) and in oral squamous cell
carcinoma (OSCC) has already been demonstrated in
previous studies. A critical step for activation of survivin
has been identified in the phosphorylation on Thr34 by
the main mitotic kinase p34cdc2–cyclin B1. The aim of
this work was to investigate the relationship between
survivin, its phosphorylated active form (p-survivin) and
M-phase promoting factor (MPF), p34cdc2-cyclin B1 in
oral carcinogenesis. 32 OSCCs and 17 OPLs from
surgical specimens were studied for cyclin B1, psurvivin,
survivin, and p34cdc2 expression by
immunohistochemistry. All cases of OSCC expressed
survivin and its expression rate was correlated to psurvivin
levels (P<0.05). Cyclin B1 was positive in 80%
of cases, while p-34cdc2 was over-expressed in all
OSCCs. All OPLs associated with OSCC expressed
survivin and its levels were correlated to p-survivin
levels (P<0.05). Cyclin B1 was positive in 70% of cases,
while p-34cdc2 was positive in all OPLs. In conclusion,
this study demonstrated that MPF, survivin and psurvivin
are expressed during early and late phase of oral carcinogenesis. MPF proteins, which are co-expressed
on mitotic apparatus, could represent a potential target
for therapies based on manipulation of survivin
phosphorylation, which would induce apoptosis in
cancer cells
