Connexin43 (cx43), a gap junction protein, is implicated in the suppression of tumor cell growth. Numerous cancer cells show a reduction or loss of cx43 expression compared to their normal counterparts. Our previous studies suggest that cx43 expression is decreased in a variety of human brain tumor cell lines. To further investigate the role of cx43 in the development of human gliomas, we performed the present study on human glioma grades I-IV. ⋯ Our data support the hypothesis that reduction of cx43 is involved in the progression of human gliomas.

We present the interim findings of our in-house protocol treating the tumor bed alone after lumpectomy with low-dose-rate (LDR) interstitial brachytherapy in selected patients with early-stage breast cancer treated with breast conserving therapy (BCT). ⋯ Interim results with treatment of the tumor bed alone with an LDR interstitial implant appear promising. Long-term follow-up of these patients and additional studies will be necessary to establish the equivalence of this treatment approach compared to standard BCT.
