Induced collagen type-I secretion by hepatocytes of the melanoma liver metastasis is associated with a reduction in tumour-infiltrating lymphocytes.

Background: Overall patients with melanoma liver metastasis (MLiM) have a dismal prognosis and poor responses to the standard of care treatment. Understanding the role of the tumour microenvironment (TME) is critical for discovering better strategies to overcome intrinsic therapy resistance in MLiM. The aim was to understand the crosstalk signalling pathways between hepatocytes and metastatic melanoma cells in the TME of MLiM.

Interferon-induced factor 16 is essential in metastatic melanoma to maintain STING levels and the immune responses upon IFN-γ response pathway activation.

Background: Immune checkpoint inhibitor (ICIs)-based therapies are the standard of care treatment for patients with metastatic melanoma (MM). The stimulator of interferon genes (STING) signaling pathway is critical in controlling immune responses to ICIs. Interferon (IFN)-γ-inducible protein 16 (IFI16) is a cytosolic DNA sensor that activates the STING signaling pathway.

Purple maize arabinoxylan could protect antioxidant compounds during digestion.

Purple maize is a pigmented variety rich in antioxidants. Arabinoxylans (AX) are prebiotic compounds also found in the grain wall that can form gels. Recently, antioxidants have extensively been studied for their beneficial effects.

Genomic and transcriptomic landscape of HER2-low breast cancer.

Background: Novel agents have expanded the traditional HER2 definitions to include HER2-Low (HER2L) Breast Cancer (BC). We sought to evaluate the distinct molecular characteristics of HER2L BC to understand potential clinical/biologic factors driving resistance and clinical outcomes.

Methods: Retrospective analysis was performed on 13,613 BC samples, tested at Caris Life Sciences via NextGen DNA/RNA Sequencing.
