Abstract
The lysophosphatidic acid 3 receptor (LPA3) participates in different physiological actions and in the pathogenesis of many diseases through the activation of different signal pathways. Knowledge of the regulation of the function of the LPA3 receptor is a crucial element for defining its roles in health and disease. This review describes what is known about the signaling pathways activated in terms of its various actions. Next, we review knowledge on the structure of the LPA3 receptor, the domains found, and the roles that the latter might play in ligand recognition, signaling, and cellular localization. Currently, there is some information on the action of LPA3 in different cells and whole organisms, but very little is known about the regulation of its function. Areas in which there is a gap in our knowledge are indicated in order to further stimulate experimental work on this receptor and on other members of the LPA receptor family. We are convinced that knowledge on how this receptor is activated, the signaling pathways employed and how the receptor internalization and desensitization are controlled will help design new therapeutic interventions for treating diseases in which the LPA3 receptor is implicated.

Abstract
Lysophosphatidic acid (LPA, 1-acyl-2-hemolytic-sn-glycerol-3-phosphate) extracted from membrane phospholipid is a kind of simple bioactive glycophospholipid, which has many biological functions such as stimulating cell multiplication, cytoskeleton recombination, cell survival, drug-fast, synthesis of DNA and ion transport. Current studies have shown that six G-coupled protein receptors (LPAR1-6) can be activated by LPA. They stimulate a variety of signal transduction pathways through heterotrimeric G-proteins (such as Gα12/13, Gαq/11, Gαi/o and GαS). LPA and its receptors play vital roles in cancers, nervous system diseases, cardiovascular diseases, liver diseases, metabolic diseases, etc. In this article, we discussed the structure of LPA receptors and elucidated their functions in various diseases, in order to better understand them and point out new therapeutic schemes for them.

Abstract
G-protein-coupled receptor 120 (GPR120) and GPR40 exhibit a variety of biological responses by the binding of free fatty acids. 12-O-Tetradecanoylphorbol-13-acetate (TPA) is a tumor promoting agent of skin carcinogenesis. It is known that TPA treatment stimulates cell motile activity of cancer cells, including melanoma cells. In the present study, we investigated whether GRP120 and GPR40 are involved in regulation of cell motile activity induced by TPA in two melanoma cell lines. A375 and G361 cells were treated with TPA at a concentration of 10 nM for 24 h. The cell motile activity of A375 cells was significantly increased by TPA, correlating with GPR40 expression. In contrast, TPA suppressed the cell motile activity of G361 cells, while GPR120 and GPR40 expressions were increased. The cell motile activity of A375 cells treated with TPA was markedly increased by GPR120 knockdown. In addition, to assess roles of GPR120 and GPR40 in cellular functions of A375 cells by the long-term TPA treatment, cells were treated with TPA (1 nM) for at least 3 months. The long-term TPA treatment induced the high cell motile activity and elevated GPR120 and GPR40 expressions. The high cell motile activity of A375 cells stimulated by the long-term TPA treatment was enhanced by GPR120 knockdown. These results suggest that GPR120 negatively and GPR40 positively regulate cell motile activities induce by TPA in melanoma cells.

Abstract
Euphorbia tirucalli (L.), commonly known as aveloz, has been indiscriminately used in popular medicine to treat various illnesses. However, some components can have devastating consequences. Injury to a cell's genetic material can cause mutations, cancer, and cell death. Our main goal in this work was to evaluate the genotoxic and cytotoxic effects of E. tirucalli extract on human leukocytes. For this purpose, we performed a phytochemical analysis to evaluate the plant's components. In the second step, we treated cultured human leukocytes with different concentrations of the dry extract of the plant and then evaluated the oxidative and genotoxic profiles of these leukocytes. We found that at 1% and 10% concentrations, the aveloz extract acted as a genotoxic agent that could damage DNA and increase oxidative damage. We conclude that despite its popular use, aveloz can act as a genotoxic agent, especially when it contains phorbol ester. Aveloz's indiscriminate use might actually promote tumors and therefore carry a considerable genetic risk for its users.

Abstract
Lysophosphatidic acid (LPA) signaling via LPA receptors provides a variety of cellular functions, including angiogenesis. In this study, to assess an involvement of LPA receptors in cell motile activities of endothelial cells during chemotherapy, F-2 cells were treated with cisplatin (CDDP) and doxorubicin (DOX) at a concentration of 0.01 μM every 24 h for at least 1 month. The treatment of CDDP and DOX inhibited the expression levels of the LPA receptor-1 (Lpar1), Lpar2, and Lpar3 genes in F-2 cells. The cell motile activities of CDDP and DOX treated cells were relatively lower than those of untreated cells. Next, we investigated whether cancer cells could stimulate the cell motile activities of F-2 cells treated with CDDP and DOX. For cell motility assay, CDDP- and DOX-treated cells were co-cultured with pancreatic cancer PANC-1 cells. The cell motile activities of CDDP- and DOX-treated cells were significantly enhanced by the existence of PANC-1 cells, correlating with the LPA receptor expressions. In addition, the elevated cell motile activities were suppressed by the pretreatment of an autotaxin inhibitor S32826. These results suggest that LPA signaling via LPA receptors may regulate the cell motile activities of F-2 cells treated with anticancer drugs.

Abstract
Lysophosphatidic acid (LPA) is a bioactive lipid that interacts with G protein-coupled LPA receptors (LPA receptor-1 (LPA1) to LPA6). Here, we investigated the effects of LPA signaling via LPA5 on cellular functions of sarcoma cells by generating Lpar5 overexpressing and Lpar5 knockdown cells from rat osteosarcoma and malignant fibrous histiocytoma cells, respectively. The cell motility activity of Lpar5 overexpressing cells was significantly lower, while Lpar5 knockdown cells showed high cell motility, compared with respective controls. Gelatin zymography showed that LPA5 suppressed the activation of matrix metalloproteinase-2. LPA5 also inhibited the cell motility activity of endothelial cells, correlating with the expression levels of vascular endothelial growth factor genes. These results suggest that LPA signaling via LPA5 negatively regulates the cellular functions of rat sarcoma cells.

Abstract
Lysophosphatidic acid (LPA) signaling via G protein-coupled transmembrane LPA receptors (LPA1 to LPA6) mediates a variety of cellular functions, including cell proliferation, migration, morphogenesis, and differentiation. Recently, we demonstrated that the different induction of LPA receptors by estrogens regulates cell motile activity of rat liver epithelial WB-F344 cells. In the present study, to assess whether endocrine disruptors (EDs) are involved in cellular functions through LPA signaling, we measured cell motile activity and LPA receptor expressions in WB-F344 cells treated with bisphenol A (BPA) and 4-nonylphenol (4-NP). Using quantitative real time RT-PCR analysis, the Lpar1 expression was elevated in BPA-treated cells, whereas the Lpar3 expression was decreased. In contrast, 4-NP increased the Lpar3 expression, but not the Lpar1 and Lpar2. For cell motility assay with a Cell Culture Insert, cell motile activity of BPA-treated cells was significantly lower than that of untreated cells. In contrast, 4-NP markedly enhanced cell motile activity. The effects of BPA and 4-NP on cell motility were inhibited by the Lpar1 or Lpar3 knockdown. These results suggest that BPA and 4-NP may regulate cell motile activity through the different induction of LPA receptors in WB-F344 cells.

Abstract
Matrix metalloproteinases (MMPs) play an important role in cancer metastasis, cell migration and invasion. Herein, we investigated the effects of silibinin on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced cell migration and MMP-9 expression in thyroid and breast cancer cells. Our results revealed that the levels of MMP-9 mRNA and protein expression were significantly increased by TPA but not MMP-2 in TPC-1 and MCF7 cells. To verify the regulatory mechanism of TPA-induced MMP-9 expression, we treated TPC-1 and MCF7 cells with the MEK1/2 inhibitor, UO126, and TPA-induced MMP-9 expression was significantly decreased. We also found that TPA-induced cell migration and MMP-9 expression was significantly decreased by silibinin. In addition, TPA-induced phosphorylation of MEK and ERK was also inhibited by silibinin. Taken together, we suggest that silibinin suppresses TPA-induced cell migration and MMP-9 expression through the MEK/ERK-dependent pathway in thyroid and breast cancer cells.

Recently, we demonstrated that each LPA receptor acts as a positive or negative regulator of cell migration ability. It is known that estrogens indicate a variety of biological functions, including cell motility. In the present study, to assess whether LPA signaling is involved in cell motile activity stimulated by estrogens, we measured cell motile activity and LPA receptor expressions of rat liver epithelial WB-F344 cells treated with 17β-estradiol (E(2)), ethinyl estradiol (EE) and diethylstilbestrol (DES) at concentrations of 0.1 and 1.0 μM for 48 h. The cell motility of E(2) and EE treated cells was significantly higher than that of untreated cells. By contrast, DES markedly inhibited cell motile activity. Using quantitative real time RT-PCR analysis, Lpar1 and Lpar3 expressions in E(2) treated cells were significantly higher than those in untreated cells. In EE treated cells, Lpar3 expression was markedly elevated, whereas Lpar1 expression was decreased. On the other hand, Lpar1 expression was significantly increased in DES treated cells. Interestingly, the effects of E(2), EE and DES on cell motility were suppressed by Lpar1 or Lpar3 knockdown. These results suggest that the different induction of LPA receptors by estrogens may regulate cell motile activity of WB-F344 cells.

Abstract
Lysophosphatidic acid (LPA) mediates a variety of cellular responses with atleast six G protein-coupled transmembrane receptors (LPA receptor-1 (LPA(1)-LPA(6))). The interaction between LPA receptors and other cellular molecules on the biological function is not fully understood. Recently, we have reported that LPA(1) suppressed and LPA(3) stimulated cell migration of pancreatic cancer cells. In the present study, to evaluate the function of LPA(2) on motile and invasive activities of pancreatic cancer cells, we generated Lpar2 knockdown (HPD-sh2) cells from hamster pancreatic cancer cells and measured their cell migration ability. In cell motility and invasive assays with an uncoated Cell Culture Insert, HPD-sh2 cells showed significantly lower intrinsic activity than control (HPD-GFP) cells. Since K-ras mutations were frequently detected in pancreatic cancer, we next investigated whether oncogenic K-ras is involved in cell migration induced by LPA(2) using K-ras knockdown (HPD-K2) cells. The cell motile ability of HPD-K2 cells was significantly lower than that of control cells. To confirm LPA(2) increases cell migration activity, cells were pretreated with dioctylglycerol pyrophosphate (DGPP) which is the antagonist of LPA(1)/LPA(3). The cell motile and invasive abilities of DGPP -treated HPD-GFP cells were markedly higher than those of untreated cells, but DGPP did not stimulate cell migration of HPD-K2 cells. These results suggest that cell migration activity of pancreatic cancer cells stimulated by LPA(2) may be enhanced by oncogenic K-ras.

Abstract
Lysophosphatidic acid (LPA) acts as a simple phospholipid that interacts with G protein-coupled transmembrane LPA receptors. Recently, it has been reported that each LPA receptor plays different biological roles in acquisition of the malignant property of tumor cells. In this study, to assess the involvement of LPA receptor-3 (LPA(3)) in cell survival after treatment with anticancer drugs, we generated Lpar3-expressing FM3A-a3A9 cells from mouse mammary tumor FM3A cells and examined the cell survival rate after treatment with anticancer drugs compared with Lpar3-unexpressing cells. Cells were treated with 0.005 to 10 μM of cisplatin (CDDP) or doxorubicin (DOX) for 3 days. For the CDDP and DOX treatments, the cell survival rate of FM3A-a3A9 cells was significantly higher than that of Lpar3-unexpressing cells. The expression level of the Mdr1a gene in FM3A-a3A9 cells was higher than that of Lpar3-unexpressing cells, whereas no significant difference in multidrug resistance 1b (Mdr1b) and glutathione S-transferase mu1 (Gstm1) expressions was found. These results suggest that LPA(3) may enhance the cell survival rate after treatment with anticancer drugs in mouse mammary tumor cells, correlating with increased expression of the Mdr1 gene.
