Data on the evaluation of FGF2 gene expression in Colorectal Cancer.

The data presented in this article is related with the research paper entitled "Evaluation of MGP gene expression in colorectal cancer", available on Gene journal [1]. From all the transcription factors known to regulate MGP, FGF2 is the most described in colon adenocarcinoma and colon tumor cell lines, where it was shown to: i) contribute for the invasiveness potential; and ii) promote proliferation and survival of colorectal cancer cells. These in vitro studies pose the hypothesis that FGF2 associated signaling pathways could be promoting the regulation of others genes, such as MGP, that may lead to tumor progression which ultimately could result in poor prognosis in colon adenocarcinoma.

Evaluation of MGP gene expression in colorectal cancer.

PURPOSE: Matrix Gla protein (MGP) is a vitamin K-dependent, γ-carboxylated protein that was initially found to be a physiological inhibitor of ectopic calcifications affecting mainly cartilage and the vascular system. Mutations in the MGP gene were found to be responsible for a human pathology, the Keutel syndrome, characterized by abnormal calcifications in cartilage, lungs, brain and vascular system. MGP was recently implicated in tumorigenic processes such as angiogenesis and shown to be abnormally regulated in several tumors, including cervical, ovarian, urogenital and breast. This fact has triggered our interest in analyzing the expression of MGP and of its regulator, the transcription factor runt related transcription factor 2 (RUNX2), in colorectal cancer (CRC). METHODS: MGP and RUNX2 expression were analyzed in cancer and non-tumor biopsies samples from 33 CRC patients and 9 healthy controls by RT-qPCR. Consequently, statistical analyses were performed to evaluate the clinical-pathological significance of MGP and RUNX2 in CRC. MGP protein was also detected by immunohistochemical analysis. RESULTS: Showed an overall overexpression of MGP in the tumor mucosa of patients at mRNA level when compared to adjacent normal mucosa and healthy control tissues. In addition, analysis of the expression of RUNX2 mRNA demonstrated an overexpression in CRC tissue samples and a positive correlation with MGP expression (Pearson correlation coefficient 0.636; p ≤ 0.01) in tumor mucosa. However correlations between MGP gene expression and clinical-pathological characteristics, such as gender, age and pathology classification did not provide relevant information that may shed light towards the differences of MGP expression observed between normal and malignant tissue. CONCLUSIONS: We were able to associate the high levels of MGP mRNA expression with a worse prognosis and survival rate lower than five years. These results contributed to improve our understanding of the molecular mechanism underlying MGP deregulation in cancer.

[Variables related to the emergence of differential patterns in work motivation]. / Factores asociados a la emergencia de patrones diferenciales de la motivación en el trabajo.

Several longitudinal studies have shown that motivation at work acts chaotically. In very few cases, it may be linear or random. However, the factors that might explain why these different patterns emerge have not been analysed to date. In this exploratory study, we interviewed 73 employees whose motivational patterns were previously known. The results revealed that chaotic patterns were associated with high levels of motivation, self-efficacy beliefs, and perceptions of instrumentality, and also with intrinsic personal goal orientation and a perception of high work control. Linear patterns were associated with extrinsic goals and a perception of work as difficult, and random patterns were linked to high flexibility at work.

Factores asociados a la emergencia de patrones diferenciales de la motivación en el trabajo / Variables related to the emergence of differential patterns in work motivation

Diferentes investigaciones usando diseños longitudinales han logrado identificar que la motivación en el trabajo se comporta principalmente de forma caótica y excepcionalmente mostrando otro tipo de comportamientos (lineal o azaroso). Sin embargo, hasta el momento no se ha estudiado acerca de los factores explicativos de la emergencia de estos patrones distintos. Con el objetivo de afrontar esta cuestión, 73 trabajadores, cuyo patrón motivacional era conocido, fueron entrevistados con el fin de estudiar de manera exploratoria una serie de aspectos de su trabajo. Los resultados revelaron que el patrón caótico se asoció a altos valores de motivación, autoeficacia y percepción de instrumentalidad, orientación a metas personales intrínsecas y a una alta percepción de control sobre el trabajo. Frente a ellos el patrón lineal se asoció con metas extrínsecas y una percepción del trabajo como difícil y el patrón azaroso apareció asociado con una alta flexibilidad en el trabajo
