New marker
substance for cancer cells
Scientists
from ETH Zurich
have developed a new substance that enables certain tumour types to be rendered
visible in high resolution using positron emission tomography. The so-called
tracer has successfully been tested in mice. Now the researchers are planning
clinical trials in humans.

MicroRNA
Drives Both Cancer Onset and Metastasis
A mere 25
years ago, noncoding RNAs were considered nothing more than "background
noise" in the overall genomic landscape. Now, two new studies reveal that
one of these tiny noncoding molecules -- microRNA-22 -- plays an outsized role
in two types of cancer.

Cancer-linked
FAM190A gene found to regulate cell division
Johns
Hopkins cancer scientists have discovered that a little-described gene known as
FAM190A plays a subtle but critical role in regulating the normal cell division
process known as mitosis, and the scientists' research suggests that mutations
in the gene may contribute to commonly found chromosomal instability in cancer.

Gene That
Controls Aggressiveness in Breast Cancer Cells Identified
In
a discovery that sheds new light on the aggressiveness of certain breast
cancers, Whitehead Institute researchers have identified a transcription
factor, known as ZEB1, that is capable of converting non-aggressive basal-type
cancer cells into highly malignant, tumor-forming cancer stem cells (CSCs).
Intriguingly, luminal breast cancer cells, which are associated with a much
better clinical prognosis, carry this gene in a state in which it seems to be
permanently shut down.

Cancer : la radiothérapie entre au
bloc
Radiophysicienne à l'hôpital
Saint-Louis, à Paris, Ramona Itti pousse la console de radiothérapie mobile
jusqu'à l'ascenseur. Direction le deuxième étage. Il est près de midi, ce jour
de mai. La météo en berne n'affecte guère le moral des troupes : dans la salle
aveugle du bloc chirurgical, les murs ont été blindés par vingt centimètres de
béton ; les portes, par une fine couche de plomb. Une sécurité imposée par la
réglementation française, et dûment contrôlée par l'Autorité de sûreté
nucléaire (ASN).

Cancer professionnel : la difficile
question de la reconnaissance
D’après des chiffres parus en 2003,
le travail aurait été responsable de 11.000 à 23.000 cancers en France. Tous ne
sont cependant pas reconnus comme tel. La question de la causalité reste
souvent délicate à déterminer. Mais pourquoi ?
