All of these agents are poorly soluble particles that are weakly toxic, and were chosen for assessment because evidence suggests that they cause cancer in the respiratory tract of rats through mechanisms similar to those

In the present study, we continued to define the underlying mechanisms of the antiadhesive function of HKa. The characterization of the binding interactions to different adhesion receptors as well as to VN-rich matrices revealed that HKa is responsible for the disruption of uPAR and ␣v 3 integrin-dependent cellular contacts.

Ovarian cancer is one of the most common gynaecological neoplasms, especially in industrialised countries. The aetiology of the disease is not well understood, except that inherited mutations in the breast cancer genes BRCA-1 and BRCA-2 account for up to 10% of all cases,[1][1] and child-bearing, oral contraceptive use and breast-feeding reduce the risk.[2][2] Some environmental exposures
