ADSL-generated fumarate binds and inhibits STING to promote tumour immune evasion.

Highly aggressive tumours have evolved to restrain the cGAS-STING pathway for immune evasion, and the mechanisms underlying this hijacking remain unknown. Here we demonstrate that hypoxia induces robust STING activation in normal mammary epithelial cells but not in breast cancer cells. Mechanistically, adenylosuccinate lyase (ADSL), a key metabolic enzyme in de novo purine synthesis, is highly expressed in breast cancer tissues and is phosphorylated at T350 by hypoxia-activated IKKβ.

[Insight into the grading of breast phyllodes tumors].

Phyllodes tumors (PT) of the breast is a rare fibroepithelial tumor, which can be divided into benign, borderline and malignant pathological types according to its histological characteristics. Malignant phyllodes tumor (MPT) accounts for 10%-20% of PT and has the ability of local recurrence and distant metastasis. Therefore, accurate diagnosis and identification of MPT are particularly important for patients to obtain appropriate treatment at the initial diagnosis.

The potential neuro-oncology link of GALR1 protein molecular mechanism in breast cancer: Expression in BT549 and MDA-MB-231 cells and its role in proliferation and migration.
