COX5A promotes cell progression and cisplatin‐resistance by alleviating mitochondrial dysfunction in head and neck squamous cell carcinoma

Precision Medical Sciences, EarlyView.
COX5A promotes cell progression and cisplatin‐resistance and alleviates mitochondrial dysfunction. ISG15 shows a reversing role with COX5A. Targeting the COX5A‐mediated mitochondrial metabolic pathway may offer a novel therapeutic approach to enhance cisplatin sensitivity in HNSCC.

The Yolk Sac Feeds Pancreatic Tumors [PDF]

Immunity, 2017
In this issue of Immunity, Zhu et al. (2017) report that tumor-associated macrophages in a mouse model of pancreatic ductal adenocarcinoma (PDAC) originate from both the yolk sac (YS) and bone marrow. Differential ablation of these populations indicates that only the YS-derived macrophages promote PDAC progression and growth.
