Gastric cancer is an important cancer type worldwide, the anti‑angiogenic agent BC001 can target the vascular endothelial growth factor receptor 2 (VEGFR2), and significantly suppresses the growth of gastric cancer BGC823 cells in vitro and in vivo. However, numerous results indicated that antiangiogenic drugs could induce autophagy, and the inhibition of autophagy enhanced the anticancer effects of antiangiogenic agents. In the present study, hydroxychloroquine (HCQ), an inhibitor of autophagy, enhanced the antiproliferative and proapoptotic effects of BC001 in vitro. Furthermore, HCQ enhanced the antitumor effects of BC001 on BGC823 xenograft tumors in vivo. Of note, BC001 neither induced nor inhibited autophagy. RNA‑sequencing results revealed that HCQ regulated autophagy or lysosomal‑associated genes, such as tumor protein p53‑inducible nuclear protein 1, interleukin (IL)1B, tumor necrosis factor (TNF), Mediterranean fever, ubiquitin specific peptidase 36, IL6, neuraminidase (NEU)1, ATP‑binding cassette subfamily A member 1, proprotein convertase subtilisin/kexin type 9, myelin basic protein and NEU3. Importantly, HCQ was determined to affect multiple pathways, including 'negative regulation of endothelial cell proliferation', 'blood vessel remodeling', 'cell surface receptor signaling pathways' and 'notch receptor processing' associated with 'signal transduction', 'cancers' and 'immune system', through regulating C‑X‑C motif chemokine ligand 8, TNF, IL6, intercellular adhesion molecule 1 and FOS genes. In summary, HCQ was proposed to enhance the anticancer effects of BC001 in gastric cancer via complex mechanisms.

Computable knowledge regarding functions of genes and gene products. GO resources include biomedical ontologies that cover molecular domains of all life forms as well as extensive compilations of gene product annotations to these ontologies that provide largely species-neutral, comprehensive statements about what gene products do. Used to standardize representation of gene and gene product attributes across species and databases.
