Abstract Text Activating germline mutations of anaplastic lymphoma kinase (ALK) occur in most cases of hereditary neuroblastoma (NB) and the constitutively active kinase activity of ALK promotes cell proliferation and survival in NB. Therefore, ALK kinase is a potential therapeutic target for NB. In this study, we show that the novel ALK inhibitor alectinib effectively suppressed cell proliferation and induces apoptosis in NB cell lines with either wild-type ALK or mutated ALK (F1174L and D1091N) by blocking ALK-mediated PI3K/Akt/mTOR signaling. In addition, alectinib enhanced doxorubicin-induced cytotoxicity and apoptosis in NB cells. Furthermore, alectinib induced apoptosis in an orthotopic xenograft NB mouse model. Also, in the TH-MYCN transgenic mouse model, alectinib resulted in decreased tumor growth and prolonged survival time. These results indicate that alectinib may be a promising therapeutic agent for the treatment of NB.

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

ALK D1091N neuroblastoma sensitive AZD3463 + Doxorubicin Preclinical - Cell culture Actionable In a preclinical study, AZD3463 treatment enhanced the cytotoxic effects of Adriamycin (doxorubicin) in a neuroblastoma cell line harboring ALK D1091N, demonstrating increased apoptotic activity and decreased cell viability in culture (PMID: 28455243). 28455243
ALK D1091N neuroblastoma predicted - sensitive Alectinib Preclinical - Cell culture Actionable In a preclinical study, Alecensa (alectinib) treatment in a neuroblastoma cell line harboring ALK D1091N resulted in decreased cell viability, inhibition of colony formation, and inhibition of Pi3k pathway signaling in culture (PMID: 28455243). 28455243
