Lauroside B, a Megastigmane Glycoside from Laurus Nobilis (Bay Laurel) Leaves, Induces Apoptosis in Human Melanoma Cell Lines by Inhibiting NF-κB Activation
Malignant melanoma is a highly aggressive tumor that frequently resists chemotherapy, so the search for new agents for its treatment is of great importance. In the present study, the antiproliferative propensity against human melanoma cell lines of lauroside B (1), a megastigmane glycoside isolated from Laurus nobilis (bay laurel) leaves, was investigated. This compound suppressed the proliferation of three human melanoma cell lines, namely, A375, WM115, and SK-Mel-28. The 1-induced inhibition of human melanoma cell proliferation was due to the induction of apoptosis, as demonstrated by FACS analysis with annexin V/PI staining and confirmed by activation of caspase-3 and by the cleavage of …
In search of an integrated framework of business longevity
Even if the domain of business longevity has been enriched by the multidisciplinary nature of approaches used to investigate the phenomenon, the lack of a unifying perspective has impeded systematic research and caused definitional ambiguity. The main aim of this special issue is to extend existing knowledge on business longevity by integrating theoretical and empirical studies that adopt different approaches and perspectives. This is essential in order to identify the key factors of long-term success and the effects of longevity on firm performance. The multifaceted nature of business longevity research is mirrored in the five articles included in this special issue, that offer different a…
