Lung tumor-associated antigens of approximately 32,000 daltons were recognized by the use of sensitive radioimmunoassays and rabbit antisera, one raised against an extract of pooled human malignant lung tissues and another raised against a cell line derived from a human squamous cell carcinoma of the lung. These antigens differ from antigens described previously, including carcinoembryonic antigen and alpha-fetoprotein. The antigens were detected on 13 of 13 lung tumors (of all histologic types), fetal tissue, normal brain, 2 of 8 colon tumors, 2 of 9 prostate tumors, and 2 of 3 breast tumors, as well as on cell lines derived from lung tumors, neuroblastoma, human amnion, colon adenocarcinoma, and bladder tumors. They were not detectable on normal lung, liver, kidney, colon, or prostate tissues or on cell lines derived from osteosarcoma, fetal lung fibroblasts, transitional cell carcinoma, and squamous cell carcinoma of the skin. Lung tumors of different histologic types were concluded to express common, tumor-associated oncofetal antigens that are found less often on tumors of other organs.

A few years ago Everson and I assembled all the examples of spontaneous regression in the world medical literature from 1900 to 1960 and added numerous cases from expriences of our friends. Our figure was 176. We excluded squamous cell carcinoma of the skin, leukemia, Hodgkin's disease, and a large number of cases that did not fulfill the prerequisites of confirmed diagnosis and no significant treatment. The four most common examples of regression were carcinoma of the kidney (31), neuroblastoma (29), malignant melanoma (19), and choriocarcinoma (19); these constituted more than half the group. We did not require that the regression be permanent because it appeared that the explanation of temporary regression would be just as important as the cause of permanent regression. There was no proven specific cause of the regression, but the following mechanisms had a possible relationship: immunologic action, elimination of carcinogens, trauma (altering the antigen-antibody relationship), hormones, irradiation, infection and/or fever, and drugs or chemicals. The most applicable of these is elimination of the carcinogen. Immunologic reactions seem to offer the best explanation, and the potential of humoral immunity is more impressive than that of cellular immunity.

The Grainyhead-like (GRHL) family of transcription factors has three mammalian members, which are currently termed Grainyhead-like 1 (GRHL1), Grainyhead-like 2 (GRHL2), and Grainyhead-like 3 (GRHL3). These factors adopt a DNA-binding immunoglobulin fold homologous to the DNA-binding domain of key tumor suppressor p53. Their patterns of expression are tissue and developmentally specific. Earlier studies of the GRHL proteins focused on their functions in mammalian development. In recent years, these factors have been linked to many different types of cancer: squamous cell carcinoma of the skin, breast cancer, gastric cancer, hepatocellular carcinoma, colorectal cancer, clear cell renal cell carcinoma, neuroblastoma, prostate cancer, and cervical cancer. The roles of GRHL proteins in these various types of cancer are complex, and in some cases appear to be contradictory: they can serve to promote cancer development, or they may act as tumor suppressors, depending on the particular GRHL protein involved and on the cancer type. The reasons for obvious discrepancies in results from different studies remain unclear. At the molecular level, the GRHL transcription factors regulate the expression of genes whose products are involved in cellular proliferation, differentiation, adhesion, and polarity. We herein review the roles of GRHL proteins in cancer development, and we critically examine relevant molecular mechanisms, which were proposed by different authors. We also discuss the significance of recent discoveries implicating the involvement of GRHL transcription factors in cancer and highlight potential future applications of this knowledge in cancer treatment.
