Abstract
Proteomic analysis shows that treatment of keratinocytes cultures with all trans retinoic acid (ATRA), under condition in which it inhibits cell growth, results in marked decrease of the level of the F1-β subunit of the catalytic sector of the mitochondrial FoF1 ATP synthase complex. Enzymatic analysis shows in ATRA-treated keratinocytes a consistent depression of the ATPase activity, with decreased olygomycin sensitivity, indicating an overall alteration of the ATP synthase complex. These findings, together with the previously reported inhibition of respiratory complex I, show that depression of the activity of oxidative phosphorylation enzymes is involved in the cell growth inhibitory action of ATRA.

Abstract
High telomerase activity promotes tumor growth by stabilizing damaged chromosomes and their mitotic replication. Overactivation of telomerase activity has been reported in cervical cancer, a malignancy caused by high-risk human papillomaviruses (HR-HPVs). The HR-HPV E6 can activate hTERT promoter by interacting with E6AP or other binding proteins and by stabilizing the interaction between hTERT and E6AP. GRIM-19 is a novel tumor suppressor that affects multiple targets in a cell to regulate growth. We have previously reported the interaction of GRIM-19 with 18E6 and E6AP to disrupt the E6/E6AP complex and increase the autoubiquitination of E6AP. In this study, we characterized the interaction of GRIM-19 with 16E6 (an oncoprotein produced by HPV16) and identified the binding sites that mediate this interaction. We also found that GRIM-19 expression in cervical cancer cells could inhibit telomerase activity by inhibiting the transactivation of the hTERT promoter by E6, thereby promoting cervical cancer cell senescence. Moreover, we identified a negative correlation between GRIM-19 and hTERT expression in cervical cancer tissues. Suppression of GRIM-19 and induction of hTERT levels were associated with lymph node metastasis, advanced clinical stage, and poor prognosis. This study identified another important novel antitumor molecular link associated with GRIM-19 in the tumorigenesis.

Abstract
Lung cancer is currently the leading cause of cancer-related death in the world. Signal transducers and activators of transcription 3 (STAT3) is a major oncogenic transcription factor involved in the development and progression of a number of human tumors including lung denocarcinoma. Gene associated with retinoid-interferon-induced mortality-19 (GRIM-19) is known to functionally interact with STAT3 and inhibit its transcriptional activity. Decreased expression of GRIM-19 has been reported in tumors including those from kidney, prostate, colon and cervix, indicating that loss of GRIM-19 may be involved in the tumorigenesis through activation of the STAT3 pathway. In this study, we determined that GRIM-19 was significantly reduced at the mRNA and protein levels in lung adenocarcinoma tissues. Moreover, STAT3 was increased in these tumors and corresponding changes in the expression of its downstream target genes was observed. Overexpression of GRIM-19 was also found to suppress lung adenocancinoma tumor growth both in vitro and in vivo. Taken together, these findings will likely contribute to the future development of GRIM-19-based gene therapy approaches to treat lung adenocancinoma.

Abstract
Work is presented on the role of cAMP-dependent protein phosphorylation in post-translational processing and biosynthesis of complex I subunits in mammalian cell cultures. PKA-mediated phosphorylation of the NDUFS4 subunit of complex I promotes in cell cultures in vivo import/maturation in mitochondria of the precursor of this protein. The import promotion appears to be associated with the observed cAMP-dependent stimulation of the catalytic activity of complex I. These effects of PKA are counteracted by activation of protein phosphatase(s). PKA and the transcription factor CREB play a critical role in the biosynthesis of complex I subunits. CREB phosphorylation, by PKA and/or CaMKs, activates at nuclear and mitochondrial level a transcriptional regulatory cascade which promotes the concerted expression of nuclear and mitochondrial encoded subunits of complex I and other respiratory chain proteins.

Abstract
Cervical cancer is the most common malignant disease responsible for the deaths of a large number of women in the developing world. Although certain strains of human papillomavirus (HPV) have been identified as the cause of this disease, events that lead to formation of malignant tumors are not fully clear. STAT3 is a major oncogenic transcription factor involved in the development and progression of a number of human tumors. However, the mechanisms that result in loss of control over STAT3 activity are not understood. Gene associated with Retinoid-Interferon-induced Mortality-19 (GRIM-19) is a tumor-suppressive protein identified using a genetic technique in the interferon/retinoid-induced cell death pathway. Here, we show that reduction in GRIM-19 protein levels occur in a number of primary human cervical cancers. Consequently, these tumors tend to express a high basal level of STAT3 and its downstream target genes. More importantly, using a surrogate model, we show that restoration of GRIM-19 levels reestablishes the control over STAT3-dependent gene expression and tumor growth in vivo. GRIM-19 suppressed the expression of tumor invasion- and angiogenesis-associated factors to limit tumor growth. This study identifies another major novel molecular pathway inactivated during the development of human cervical cancer.
