In the tumor microenvironment, hypoxia and stromal interactions contribute to enhanced malignant behavior in cancer cells. This study aimed to assess whether pancreatic cancer cells with higher malignancy display stronger responses to hypoxia and stromal cells than their less malignant parental cells, and evaluated the underlying mechanisms, focusing on lysophosphatidic acid (LPA) receptor signaling linked to the acquisition of malignant traits. Highly invasive PANC-M10 cells, derived from the parental pancreatic cancer PANC-1 cells, were cultured at 1% O Show less

Lysophosphatidic acid (LPA) receptor-mediated signaling contributes to the pathogenesis of cancer. The tumor microenvironment (TME), composed of cancer cells and surrounding stromal cells, plays a key role in promoting malignant traits, including resistance to anticancer drugs. In this study, we investigated the roles of LPA receptor-1 (LPA Show less

Hypoxia plays a crucial role in driving tumor progression by altering cellular signaling pathways. Lysophosphatidic acid (LPA) receptor signaling regulates malignant properties in cancer cells, including motility and chemoresistance. This study aimed to compare the cellular functions of gastric cancer AGS cells under cobalt chloride (CoCl Show less

In solid tumors, cancer cells adapt to hypoxic and nutrient deprived environments to support malignant progression. This study examined whether hypoxic and low glucose conditions enhance malignant behaviors more strongly in highly migratory MG63-R10 cells, which are derived from osteosarcoma MG-63 cells, compared to parental MG-63 cells, and further investigated whether lysophosphatidic acid (LPA) receptor signaling regulates this adaptation. MG63-R10 and MG-63 cells were cultured under hypoxic (1% O Under 1% O These results suggest that, compared to parental MG-63 cells, highly migratory osteosarcoma MG63-R10 cells adapt their malignant cellular functions to hypoxic and low-glucose conditions through LPA receptor signaling, highlighting this pathway as a potential therapeutic target in aggressive osteosarcomas.
