Abstract Genetic alterations affecting RAS proteins are commonly found in human cancers. Roughly a fourth of melanoma patients carry activating NRAS mutations, rendering this malignancy particularly challenging to treat. Although the development targeted as well immunotherapies led substantial improvement overall survival non-NRASmut (e.g. BRAFmut</...

BACKGROUND Maintenance treatment (mt) with bevacizumab (bev) ± erlotinib (erlo) has modest effect after induction chemotherapy in metastatic colorectal cancer (mCRC). We hypothesized the efficacy of erlo to be dependent on KRAS mutational status and investigated this by exploring mt strategies with bev ± erlo and low-dose capecitabine (cap). PATIENTS AND METHODS Included patients had mCRC sch...

Interleukin (IL)-6 is an autocrine growth factor for renal cell carcinoma (RCC). We sought to determine whether p53 regulates constitutive IL-6 production. RCC cell lines containing mutant (mut) p53 produced higher levels of IL-6 than those containing wild-type (wt) p53 (P < 0.05). Transfection of wt p53 into RCC cell lines bearing mut p53 (UOK 121LN) or wt p53 (A498 and ACHN) resulted in repre...

The Tc1 transposable element family of the nematode Caenorhabditis elegans consists primarily of 1.6-kb size elements. This uniformity of size is in contrast to P in Drosophila and Ac/Ds in maize. Germline transposition and excision of Tc1 are detectable in the Bergerac (BO) strain, but not in the commonly used Bristol (N2) strain. A previous study suggested that multiple genetic components are...

The Class IIa histone deacetylases (HDAC)4 and HDAC5 play a role in neuronal survival and behavioral adaptation in the CNS. Phosphorylation at 2/3 N-terminal sites promote their nuclear export. We investigated whether non-canonical signaling routes to Class IIa HDAC export exist because of their association with the co-repressor Silencing Mediator Of Retinoic And Thyroid Hormone Receptors (SMRT...

The promoter region of telomerase reverse transcriptase (TERTp) and isocitrate dehydrogenase (IDH) have been regarded as biomarkers with distinct clinical and phenotypic features. Investigated the possible correlations between tumor location and genetic alterations would enhance our understanding of gliomagenesis and heterogeneity of glioma. We examined mutations of TERTp and IDH by direct sequ...
