Enhanced anti-cancer effects of conditioned medium from hypoxic human adult dermal fibroblasts on cervical cancer cells [dataset 1]
Ontology highlight
ABSTRACT: Hypoxia regulates fibroblast function by changing intracellular signaling and secretion factors, which influences the states of nearby cells. In this work, we investigated the effects of conditioned medium (CM) from human adult dermal fibroblasts (HDFs) cultured in normoxic and hypoxic conditions on cervical cancer (HeLa) cells. The HeLa cells showed decreased cell viability, in-creased apoptosis, and cell cycle arrest in response to CM from hypoxic-cultured HDFs (H-CM) compared with CM from normoxic-cultured HDFs (N-CM). Among the proteins up-regulated (> 2-fold) in H-CM compared with N-CM, LTBR decreased the viability of HeLa cells. Among the intracellular proteins down-regulated (> 2-fold) in HeLa cells treated with H-CM compared with N-CM, the most enriched biological process GO term and KEGG pathway were protein deubiq-uitination and hsa05166:HTLV-I infection, respectively. In the protein–protein interaction net-work of intracellular proteins with altered expression (> 2-fold), 1 up-regulated (TNF) and 8 down-regulated (ESR1, MCL1, TBP, CD19, LCK, PCNA, CHEK1, and POLA1) hub proteins were defined. Among the down-regulated hub proteins, the most enriched biological process GO term and KEGG pathway were leading strand elongation and hsa05166:HTLV-I infection, respectively. This study reveals that H-CM had enhanced anti-cancer effects on cervical cancer cells compared with N-CM, and it induced intracellular signaling patterns related to those enhanced anti-cancer effects.
