The c-myc proto-oncogene encodes a nuclear phosphoprotein which probably plays a crucial role in growth control [4]. The protein has DNA-binding activity in vitro, but its function remains unknown. While avian retroviruses carrying the closely related vmyc sequence rapidly transform myeloid cells, the cellular myc gene has been strongly implicated in several types of lymphoid neoplasia. The fun...

Hepatocellular carcinoma is one leading cause of cancer-related death and surgical resection is still one of the major curative therapies. Recently, there has been a major effort to find mechanisms involved in carcinogenesis and early relapse. c-myc gene abnormality is found in hepatocarcinogenesis. Our aim was to analyze the role of c-myc as prognostic factor in terms of overall survival and d...

A new automated MYC IHC classifier based on bivariate logistic regression is presented. The predictor relies on image analysis developed with the open-source ImageJ platform. From a histologic section immunostained for MYC protein, 2 dimensionless quantitative variables are extracted: (a) relative distance between nuclei positive for MYC IHC based on euclidean minimum spanning tree graph and (b...

C/EBP homologous protein (CHOP), also known as growth arrest and DNA damage-inducible 153 (GADD153), belongs to the CCAAT/enhancer-binding (C/EBP) family. CHOP expression is induced by unfolded response (UPR), sustained activation acts a pivotal trigger for ER stress-induced apoptosis. MicroRNA-616 located within an intron of gene. However, regulation miR-616 during UPR its function in breast c...

As part of the Reproducibility Project: Cancer Biology, we published a Registered Report (Blum et al., 2015), that described how we intended to replicate selected experiments from the paper 'Transcriptional amplification in tumor cells with elevated c-Myc' (Lin et al., 2012). Here we report the results. We found overexpression of c-Myc increased total levels of RNA in P493-6 Burkitt's lymphoma ...

The oncoprotein c-Myc plays an important role in cell proliferation, transformation, inhibition of differentiation and apoptosis. These functions most likely result from the transcription factor activity of c-Myc. As a heterodimer with Max, the c-Myc protein binds to the E-box sequence (CACGTG), which is also recognized by USF dimers. In order to test differences in target gene recognition of c...

The myc protooncogene encodes the Myc transcription factor which is the essential part of the Myc-Max network controlling fundamental cellular processes. Deregulation of myc leads to tumorigenesis and is a hallmark of many human cancers. We have recently identified homologs of myc (myc1, myc2) and max in the early diploblastic cnidarian Hydra and have characterized myc1 in detail. Here we show ...

To analyze the relationship between c-myc gene expression and chondrocyte proliferation and maturation during endochondral ossification, Day 18-19 chick embryo sterna were pulse-labeled with [3H]thymidine, and serial sections were processed for autoradiography and in situ hybridization. Proliferating chondrocytes, located in four distinct areas of the developing sternum, all contained high leve...

Previous studies have demonstrated both an elevated level of cellular myc-homologous RNA in HL-60 cultures and a decrease in this messenger RNA following the chemically induced differentiation of HL-60 cells. A nuclear transcription system isolated from HL-60 cells was used to investigate whether an alteration in the rate of transcription of the c-myc gene was associated with this decrease in m...

A cDNA library enriched with Myc-responsive cDNAs but depleted of myc cDNAs was used in a functional screen for growth enhancement in c-myc-null cells. A cDNA clone for mitochondrial serine hydroxymethyltransferase (mSHMT) that was capable of partial complementation of the growth defects of c-myc-null cells was identified. Expression analysis and chromatin immunoprecipitation demonstrated that ...
