Caveolins are vital structural proteins of Caveolae, small invaginations of the membrane. they've been proven to play an incredible function within the pathogenesis of a number of cancers. during this quantity, we'll generally specialise in the significance of Caveolin-1 in breast, prostate, lung, epidermis, colon, pancreatic and mind cancers with additionally a point out of the radical function of Caveolin-3 in breast melanoma.

Cancer Cell Culture: Methods and Protocols

With many fresh advances, melanoma mobile tradition learn is extra vital than ever ahead of. This well timed variation of melanoma telephone tradition: tools and Protocols covers the fundamental innovations of melanoma mobile biology and tradition whereas increasing upon the hot shift in mobilephone tradition tools from the iteration of recent telephone strains to using basic cells.

Die tierische Zelle in Zellkultur

Die ersten erfolgreichen Versuche zur Züchtung tierischer Zellen außerhalb des Organismus reichen zurück in den Beginn unseres Jahrhunderts. 1907 gelang HARRI­ SON durch Explantation von Gewebsstücken aus Froschembryonen der Nachweis, daß in der Embryonalentwicklung die Neuriten als Fortsätze der Nervenzelle ohne Be­ teiligung anderer Zellen gebildet werden, und daß damit eine spezifische celluläre Funktion auch außerhalb des Gesamtorganismus zu beobachten ist [310,311].

Port-Site and Wound Recurrences in Cancer Surgery: Incidence - Pathogenesis - Prevention

Up to now nine years, experiences of 'port-site' deposits following laparoscopic surgical procedure for malignancy, particularly laparoscopic resection of colonic melanoma, have solid a shadow at the knowledge of the laparoscopic technique within the surgical guy­ agement in sufferers with melanoma. these experiences of port-site deposits, a few ninety circumstances stated within the literature as much as 1999, have opened a 'can of worms' and highlighted the shortage of our wisdom on melanoma telephone migration from strong tu­ mors and the criteria that underlie their profitable implantation in surgical wounds either within the presence and shortage of a good strain pneumoperito­ neum.

A key objective of this chapter will be to highlight important aspects of this ongoing discussion and reconcile in a working model (see Fig. 3) these different and opposing functions of caveolin-1. In doing so, we will focus our attention mostly on studies dealing with the role of caveolin-1 in colorectal cancer. There, as will be eluded to in the next section, alterations in the so-called canonical Wnt signaling pathway are particularly important. 2 Caveolin-1 in Colon Cancer: The Flexible Connection to Wnt Signaling 19 Canonical Wnt Signaling in Colorectal Cancer: The Role of b-Catenin Colorectal cancer is one of the most common cancers and a leading cause of cancer death worldwide.

The lifetime risk of developing cancer in this population is estimated to be 5% [65]. Despite the fact that the incidence of this cancer has decreased in recent years as a result of the introduction of preventive measures, including the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and changes in life-style and nutrition, the disease still remains a major threat. Every year, some 550,000 patients worldwide continue to succumb to the disease [49]. In molecular and genetic terms, colorectal cancer is likely to be one of the bestunderstood solid malignancies.
