Searching for ways to improve the characterization of breast cancer we examined the relationship between the status of the FHIT gene transcript and amplification of c-myc and the c-erbB2 oncogene. Abnormal FHIT transcript was detected in 32 of 79 cancers examined. The presence of Fhit protein estimated by Western blots was evident only in cancers exhibiting a normal-sized FHIT transcript. This indicates that abnormal FHIT transcripts observed in our study did not encode any Fhit protein or the amount of such protein was very low. There was no association between the presence of aberrant FHIT gene transcript with age, tumor size, estrogen and progesterone receptor status, local metastases and histological grading. However, the abnormalities in FHIT gene transcripts were observed with different frequency depending on the histopathological type of the tumor. The aberrant FHIT transcript was detected in 60% of lobular cancers and only in 28% of ductal cancers. Analyzing the occurrence of c-myc and c-erbB2 amplification and the presence of aberrant FHIT gene transcripts we found that the aberrant FHIT transcript more frequently occurred in tissues with c-myc amplification. There was a significant (P < 0.05) correlation between the occurrence of the aberrant FHIT gene transcript with accompanying c-myc amplification and positive lymph node status. However, in order to evaluate the predictive value of these findings in breast cancer, an extended clinical follow up will be necessary.

Type Particle

We have reported the maturation of an intracisternal A-type particle in murine plasma cell tumor cultures and three human tumor cell cultures (rhabdomyosarcoma, lung adenocarcinoma, and osteogenic sarcoma) after IUDR-DMSO activation. In all of these studies the A-type particle seems to develop into a form with an electron dense nucleoid, presumably mature, which is also intracisternal. A similar intracisternal A-type particle has been described in leukemic guinea pigs. Although no biological activity has yet been demonstrated for these particles, on morphologic grounds, and by the manner in which they develop within the cell, they may represent members of the same family of viruses.

Metastatic Nodule

Since the report, which described the ultrastructure of a metastatic nodule of human breast cancer after estrogen therapy, additional ultrastructural observations, including some which are correlative with pertinent findings in the literature concerning mycoplasmas, have been recorded concerning the same subject. Specimen preparation was identical to that in.The mitochondria possessed few cristae, and were deteriorated and vacuolated. They often contained particulates and fibrous structures, sometimes arranged in spindle-shaped bundles, Fig. 1. Another apparent aberration was the occurrence, Fig. 2 (arrows) of linear profiles of what seems to be SER, which lie between layers of RER, and are often recognizably continuous with them.It was noted that the structure of the round bodies, interpreted as within autophagic vacuoles in the previous communication, and of vesicular bodies, described morphologically closely resembled those of some mycoplasmas. Specifically, they simulated or reflected the various stages of replication reported for mycoplasmas grown on solid nutrient. Based on this observation, they are referred to here as “mycoplasma-like” structures, in anticipation of confirmatory evidence from investigations now in progress.
