Signal integration by jnk and p38 mapk pathways in cancer development

Signal integration by JNK and p38 MAPK pathways in cancer developmentErwin F. Wagner and Ángel R. Nebreda Abstract Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK) family members function in a cell context-specific and cell type-specific manner to integrate signals that affect proliferation, differentiation, survival and migration. Consistent with the importance of these events in tumorigenesis, JNK and p38 MAPK signalling is associated with cancers in humans and mice. Studies in mouse models have been essential to better understand how these MAPKs control cancer development, and these models are expected to provide new strategies for the design of improved therapeutic approaches. In this Review we highlight the recent progress made in defining the functions of the JNK and p38 MAPK pathways in different cancers.


Froum.qxd 1/23/06 10:57 AM Page 71 A Retrospective Study of 1,925 Consecutively Placed Immediate Implants From 1988 to 2004 Barry Wagenberg, DMD1/Stuart J. Froum, DDS2 Purpose: The purpose of the present study was to evaluate implant survival rates with immediateimplant placement (IIP) into fresh extraction sockets and to determine risk factors for implant failure.Materials and Methods: A retrospective chart review was conducted of all patients in whom IIP wasperformed between January 1988 and December 31, 2004. Treatment required atraumatic toothextraction, IIP, and mineralized freeze-dried bone allograft with an absorbable barrier to cover exposedimplant threads. Implant failure was documented along with time of failure, age, gender, medical his-tory, medications taken, postsurgical antibiotic usage, site of implant placement, and reason forimplant failure. Statistical analysis was performed using chi-square and logistic regression analysismethods. Results: A total of 1,925 IIPs (1,398 machined-surface and 527 rough-surface implants)occurred in 891 patients. Seventy-one implants failed to achieve integration; a total of 77 implantswere lost in 68 patients. The overall implant survival rate was 96.0% with a failure rate of 3.7% pre-restoration and 0.3% postrestoration. Machined-surface implants were twice as likely to fail as rough-surface implants (4.6% versus 2.3%). Men were 1.65 times more likely to experience implant failure.Implants placed in sites where teeth were removed for periodontal reasons were 2.3 times more likelyto fail than implants placed in other sites. Patients unable to utilize postsurgical amoxicillin were 3.34times as likely to experience implant failure as patients who received amoxicillin. Conclusions: With a1- to 16-year survival rate of 96%, IIP following tooth extraction may be considered to be a predictableprocedure. Factors such as the ability to use postsurgical amoxicillin and reason for tooth extractionshould be considered when treatment planning for IIP. INT J ORAL MAXILLOFAC IMPLANTS 2006;21:71–80
