Apoptosis promotes early tumorigenesis

One hallmark of cancer is intrinsic or acquired resistance
to apoptosis. Surprisingly, recent studies demonstrate that
CD95/Fas/Apo1 and p53 upregulated mediator of apoptosis/
PUMA (potent inducers of the death receptor and the
mitochondrial apoptotic pathways, respectively) promote
tumorigenesis. These findings provide important insights
into the multifaceted roles of apoptosis in tumorigenesis.

EMT theory for metastases challenged during AACR

It can't be easy to stand in front of hundreds of colleagues and tell them that ten years of research has led them in the wrong direction. But at the annual meeting of the American Association for Cancer Research (AACR) earlier this month, pathologist David Tarin did just that, by challenging a leading hypothesis on how cancers metastasize...

Academic bias & biotech failures

The unspoken rule is that at least 50% of the studies published even in top tier academic journals – Science, Nature, Cell, PNAS, etc… – can’t be repeated with the same conclusions by an industrial lab.

Breast cancer: Luminal cells with an identity crisis

Breast cancer: Luminal cells with an identity crisis

Gemma K. Alderton

Abstract
Inherited mutations in BRCA1 seem to specifically increase the risk of developing basal-like breast cancers; so, Proia and colleagues investigated how BRCA1 might promote the formation of this subtype of breast cancer.Using samples from reduction mammoplasty (BRCA1+/+) and prophylactic mastectomy from individuals with BRCA1 mutations (BRCA1mut/+), Proia and colleagues transformed cell suspensions with four tumorigenic genes (TP53R175H, CCND1, PI3KCA and KRASG12V) that are
Hallmarks of cancer: the next generation. Weinberg, Hanahan. Cell 2011. PDF

Cell. 2011 Mar 4;144(5):646-74.

Los hallmarks del cáncer propuestos desde hace varios años por Weinberg incorporan ahora otras características ya propuestas por otros múltiples veces como la inflamación, la necrosis, las alteraciones metabólicas entre otras.
