Recurrent mutations in tumor suppressor FBXW7 bypass Wnt/β-catenin addiction in cancer. (PubMed, Sci Adv)

These FBXW7-mutant Wnt/β-catenin-independent tumors are susceptible to multi-cyclin-dependent kinase inhibition. An in-depth understanding of primary resistance to anti-Wnt/β-catenin therapies allows for more appropriate patient selection and use of alternative mechanism-based therapies.

Epidermal growth factor receptor (EGFR) is a target of the tumor-suppressor E3 ligase FBXW7. (PubMed, Proc Natl Acad Sci U S A)

These observations were further strengthened in CRC-derived organoid lines and validated in a cohort of patients treated with panitumumab. Our data imply that FBXW7 mutations reduce EGF dependency by disabling EGFR turnover.

A New t(7; 9)(p12; q34) Involving NOTCH1 and IKZF1 in Pediatric T-Cell Lymphoblastic Lymphoma (ASH 2023)

Summary/perspectivesThis new t(7; 9)(p12; q34) involving ICN1 illustrates the importance to look for ICN1 more extensively in parallel to NOTCH1/FBXW7 mutations in the screening of Notch1 activation pathway in T-ALL/LL specially in the event of a stratification on Notch1 status for treatment. As both NOTCH1 and IKZF1 are major actors of normal T-cell differentiation/proliferation, the oncogenic role of the fusion NOTCH1: : IKZF1 in T-ALL/LL deserves a better understanding in a larger population and will be further explored.

FBXW7-loss sensitizes cells to ATR inhibition through induced mitotic catastrophe. (PubMed, Cancer Res Commun)

ATR-inhibition induces an accelerated S-phase, leading to mitotic catastrophe and cell death caused by the high replication stress present in FBXW7-/- cells. In addition, we provide evidence in cell and organoid studies, and mining of publicly available high throughput drug screening efforts, that this genotype-specific vulnerability extends to multiple types of cancer, providing a rational means of identifying responsive patients for targeted therapy.

Genomic signatures and prognosis of advanced stage Chinese pediatric T cell lymphoblastic lymphoma by whole exome sequencing. (PubMed, Front Pediatr)

Although T-ALL and T-LBL both originate from precursor T-cells and are considered different manifestations of the same disease and the outcome of T-LBL is favorable when using T-ALL-based chemotherapy, there are differences in the gene distribution between T-LBL and T-ALL. It seems that the PI3K-Akt signaling pathway and the USP34 gene play important roles in T-LBL, but medicines targeting the USP34 gene or the PI3K-Akt pathway may be invalid.

Most patients received oxaliplatin- or irinotecan-based regimens in the first two LOTs. In this select patient cohort with KRAS G12C mutated mCRC from US academic centers, outcomes, particularly rwPFS, were poor in later lines of therapy. Frontline OS and rwPFS were longer than in other similar studies, which may be attributable to the young median age and high proportion of surgical resection in the metastatic setting observed in this cohort.
