To evaluate local inflammation in skeletal muscle from PDAC patients with or without cachexia, we performed qRT‐PCR to examine mRNA expression of inflammatory cytokines tumour necrosis factor‐alpha (TNF‐α), interleukin‐6 (IL‐6), and interleukin‐1beta (IL‐1β). The gene discussed is IL1B; the disease is Cachexia.
