EP300/CBP are histone acetyltransferases recruited onto chromatin by oncogenic transcription factors and control the transcriptional program via their activity in enhancer areas. In the December issue of Cancer Cell, Nicosia et al. offer new promise in targeting EP300/CBP using the small-molecule inhibitor CSS1477 in patients with blood tumors and no other therapeutic options.

Background: Thyroid Hormones (THs) critically impact human cancer. Although endowed with both tumor-promoting and inhibiting effects in different cancer types, excess of THs has been linked to enhanced tumor growth and progression. Breast cancer depends on the interaction between bulk tumor cells and the surrounding microenvironment in which mesenchymal stem cells (MSCs) exert powerful pro-tumorigenic activities.

Tumor-associated macrophages (TAMs) are one of the most abundant cell types in the colorectal cancer (CRC) tumor microenvironment (TME). CRC cell-derived exosomes support macrophage polarization toward an M2-like phenotype, which leads to tumor growth and metastasis. Neuroligin 1 (NLG1) is a transmembrane protein critical in synaptic function.

Background/objectives: S100A4, a small calcium-binding protein, promotes metastasis in a variety of human malignancies, but little is known about its involvement in ovarian clear cell carcinoma (OCCC). Herein, we characterized the functional role of S100A4 in this tumor type.
Methods: We analyzed immunohistochemical sections from 120 OCCC patients.

: GFI1-36N represents a single-nucleotide polymorphism (SNP) of the zinc finger protein Growth Factor Independence 1 (GFI1), in which the amino acid serine (S) is replaced by asparagine (N). The presence of the gene variant is associated with a reduced DNA repair capacity favoring myeloid leukemogenesis and leads to an inferior prognosis of acute myeloid leukemia (AML) patients. However, the underlying reasons for the reduced DNA repair capacity in leukemic cells are largely unknown.

NKp46 is a critical regulator of natural killer (NK) cell immunity, but its function in non-NK innate immune cells remains unclear. Here, we show that NKp46 is indispensable for expressing IL-2 receptor-α (IL-2Rα) by non-NK liver-resident type-1 innate lymphoid cells (ILC1s). Deletion of NKp46 reduces IL-2Rα on ILC1s by downregulating NF-κB signaling, thus impairing ILC1 proliferation and cytotoxicity in vitro and in vivo.
