Increased expression of CEA and MHC class I in colorectal cancer cell lines exposed to chemotherapy drugs
Purpose Cancer-specific immunotherapy holds great promise as an emerging treatment for advanced colorectal cancer and may be combined with standard chemotherapy to provide a synergistic inhibitory action against tumor cells. To examine the interrelationship between the immune system and chemotherapy...

| 520 | |a Purpose Cancer-specific immunotherapy holds great promise as an emerging treatment for advanced colorectal cancer and may be combined with standard chemotherapy to provide a synergistic inhibitory action against tumor cells. To examine the interrelationship between the immune system and chemotherapy, we studied the induction of both CEA, a tumor-associated antigen, and MHC class I, a major component of the antigen presenting system, in response to a number of chemotherapeutic agents. Methods The effect of a selection of standard chemotherapeutics on MHC class I and CEA expression in human colorectal cancer cell lines was determined by flow cytometry and semi-quantitative RT-PCR. In addition, studies using mice bearing tumors derived from an injected murine colon cancer cell line were performed to determine if alteration in MHC class I expression occurs in vivo following continuous infusion of chemotherapeutic agents into the peritoneal cavity, as well as to facilitate correlations between expression of this factor and therapeutic effectiveness. Results All anti-cancer drugs examined, when given at $ IC_{50} $ values, induced expression of MHC class I protein in the human colon cancer cell line, COLO201. However, expression of CEA mRNA was only induced upon exposure to 5-FU, in contrast to obscure induction following CDDP and SN-38 treatment. Combined treatment with 5-FU and CDDP gave additional effect on CEA expression in COLO201 cells. Regarding the in vivo studies in mice, the size of the murine colon cancer cell-derived tumors was reduced only in response to treatment with CDDP, which also mediated the highest induction of MHC class I expression. Conclusion These results suggest that chemotherapeutic agents trigger the immune system and cancer-specific immunotherapy may be effective when used in combination with systemic chemotherapy. | ||

To examine the interrelationship between the immune system and chemotherapy, we studied the induction of both CEA, a tumor-associated antigen, and MHC class I, a major component of the antigen presenting system, in response to a number of chemotherapeutic agents. Methods The effect of a selection of standard chemotherapeutics on MHC class I and CEA expression in human colorectal cancer cell lines was determined by flow cytometry and semi-quantitative RT-PCR. In addition, studies using mice bearing tumors derived from an injected murine colon cancer cell line were performed to determine if alteration in MHC class I expression occurs in vivo following continuous infusion of chemotherapeutic agents into the peritoneal cavity, as well as to facilitate correlations between expression of this factor and therapeutic effectiveness. Results All anti-cancer drugs examined, when given at $ IC_{50} $ values, induced expression of MHC class I protein in the human colon cancer cell line, COLO201.

To examine the interrelationship between the immune system and chemotherapy, we studied the induction of both CEA, a tumor-associated antigen, and MHC class I, a major component of the antigen presenting system, in response to a number of chemotherapeutic agents. Methods The effect of a selection of standard chemotherapeutics on MHC class I and CEA expression in human colorectal cancer cell lines was determined by flow cytometry and semi-quantitative RT-PCR. In addition, studies using mice bearing tumors derived from an injected murine colon cancer cell line were performed to determine if alteration in MHC class I expression occurs in vivo following continuous infusion of chemotherapeutic agents into the peritoneal cavity, as well as to facilitate correlations between expression of this factor and therapeutic effectiveness. Results All anti-cancer drugs examined, when given at $ IC_{50} $ values, induced expression of MHC class I protein in the human colon cancer cell line, COLO201. However, expression of CEA mRNA was only induced upon exposure to 5-FU, in contrast to obscure induction following CDDP and SN-38 treatment. Combined treatment with 5-FU and CDDP gave additional effect on CEA expression in COLO201 cells. Regarding the in vivo studies in mice, the size of the murine colon cancer cell-derived tumors was reduced only in response to treatment with CDDP, which also mediated the highest induction of MHC class I expression. Conclusion These results suggest that chemotherapeutic agents trigger the immune system and cancer-specific immunotherapy may be effective when used in combination with systemic chemotherapy.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">5-FU</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">SN-38</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CDDP</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">FACS</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">RT-PCR</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Okabe, Satoshi</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yamashita, Hironori</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Iwai, Takehisa</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sugihara, Kenichi</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of cancer research and clinical oncology</subfield><subfield code="d">Berlin : Springer, 1904</subfield><subfield code="g">129(2003), 12 vom: 15.

Increased expression of CEA and MHC class I in colorectal cancer cell lines exposed to chemotherapy drugs |
| abstract |
Purpose Cancer-specific immunotherapy holds great promise as an emerging treatment for advanced colorectal cancer and may be combined with standard chemotherapy to provide a synergistic inhibitory action against tumor cells. To examine the interrelationship between the immune system and chemotherapy, we studied the induction of both CEA, a tumor-associated antigen, and MHC class I, a major component of the antigen presenting system, in response to a number of chemotherapeutic agents. Methods The effect of a selection of standard chemotherapeutics on MHC class I and CEA expression in human colorectal cancer cell lines was determined by flow cytometry and semi-quantitative RT-PCR. In addition, studies using mice bearing tumors derived from an injected murine colon cancer cell line were performed to determine if alteration in MHC class I expression occurs in vivo following continuous infusion of chemotherapeutic agents into the peritoneal cavity, as well as to facilitate correlations between expression of this factor and therapeutic effectiveness. Results All anti-cancer drugs examined, when given at $ IC_{50} $ values, induced expression of MHC class I protein in the human colon cancer cell line, COLO201. However, expression of CEA mRNA was only induced upon exposure to 5-FU, in contrast to obscure induction following CDDP and SN-38 treatment. Combined treatment with 5-FU and CDDP gave additional effect on CEA expression in COLO201 cells. Regarding the in vivo studies in mice, the size of the murine colon cancer cell-derived tumors was reduced only in response to treatment with CDDP, which also mediated the highest induction of MHC class I expression. Conclusion These results suggest that chemotherapeutic agents trigger the immune system and cancer-specific immunotherapy may be effective when used in combination with systemic chemotherapy. |
