BANF1 is a novel prognostic biomarker linked to immune infiltration in head and neck squamous cell carcinoma.

Background: Barrier-to-autointegration factor 1 (BANF1) is an abundant and ubiquitously expressed postnatal mammalian protein that is overexpressed in numerous human cancers and can promote cancer cell proliferation. However, the role of BANF1 in prognosis remains unclear in head and neck squamous cell carcinoma (HNSCC).

Methods: BANF1 expression data were obtained from the GEO and TCGA databases.

Co-expression of Dsb proteins enables soluble expression of a single-chain variable fragment (scFv) against human type 1 insulin-like growth factor receptor (IGF-1R) in E. coli.

Type 1 insulin-like growth factor receptor (IGF-1R) is a promising therapeutic target for cancer treatment. A single-chain variable fragment (scFv) against human IGF-1R forms inclusion body when expressed in periplasmic space of E. coli routinely.
