Pregnancy promotes tumor metastasis through adenosine-induced immunosuppressive neutrophils in pre-metastatic microenvironment
Abstract Tumor metastasis is the primary cause of cancer treatment failure and mortality. Pregnant patients with cancer sometimes experience a poor prognosis and accelerated disease progression, yet the underlying mechanisms remain poorly understood. Here we show that pregnancy enhances tumor metastasis in female mice by elevating adenosine levels, which drives pre-metastatic niche remodeling.
TUFT1 stabilizes TGF-β receptor II protein and facilitates activation of hepatic stellate cells into metastasis-promoting myofibroblasts - Cell Death & Differentiation
Abstract Cancer-associated fibroblasts (CAFs) transdifferentiated from hepatic stellate cells (HSCs) are a critical determinant of liver metastasis of colorectal cancer (CRC). However, the mechanisms behind transforming growth factor β (TGF-β)-stimulated activation of HSCs into CAFs remain poorly understood. Immunoprecipitation coupled with mass spectrometry identified tuftelin 1 (TUFT1) as a novel TGF-β receptor II (TβRII) binding protein in primary human HSCs and immortalized LX2 cells.
Calcium-sensitive synaptotagmin 11-lipid interaction modulates exo-endocytosis - Nature Communications
Abstract Synaptotagmins (Syts) are the primary Ca2+-sensors for synaptic vesicle exocytosis, while most mammalian Syts are non-Ca2+-affinitive and play critical roles in neurotransmission and synaptic plasticity with unclear mechanisms. Here, we show that high-alkaline non-Ca2+-binding Syt11 exhibits higher affinity for acidic phospholipids and Ca2+-inhibited liposome-binding, thereby competing with the Ca2+-binding Syt1.
