Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Input: Consider Input: A colorectal tumor is not an isolated entity growing in a restricted location of the body. The patient's gut environment constitutes the framework where the tumor evolves and this relationship promotes and includes a complex and tight correlation of the tumor with inflammation, blood vessels formation, nutrition, and gut microbiome composition. The tumor influence in the environment could both promote an anti-tumor or a pro-tumor response.", 'A set of 98 paired adjacent mucosa and tumor tissues from colorectal cancer (CRC) patients and 50 colon mucosa from healthy donors (246 samples in total) were included in this work. RNA extracted from each sample was hybridized in Affymetrix chips Human Genome U219. Functional relationships between genes were inferred by means of systems biology using both transcriptional regulation networks (ARACNe algorithm) and protein-protein interaction networks (BIANA software).', 'Here we report a transcriptomic analysis revealing a number of genes activated in adjacent mucosa from CRC patients, not activated in mucosa from healthy donors. A functional analysis of these genes suggested that this active reaction of the adjacent mucosa was related to the presence of the tumor. Transcriptional and protein-interaction networks were used to further elucidate this response of normal gut in front of the tumor, revealing a crosstalk between proteins secreted by the tumor and receptors activated in the adjacent colon tissue; and vice versa. Remarkably, Slit family of proteins activated ROBO receptors in tumor whereas tumor-secreted proteins transduced a cellular signal finally activating AP-1 in adjacent tissue.

Input: Consider Input: To assess the activity of mTOR and downstream effector proteins in the mTOR pathway after treatment with a dual mTOR complex 1 and 2 (mTORC1/2) inhibitor (PP242) compared with that of mTOR complex 1 (mTORC1) inhibitor (rapamycin) using a xenograft tumor model.', 'Pheochromocytoma PC12 cell were xenografted into nude mice. Animals were treated with PP242 and rapamycin. Mean tumor volume was compared across groups. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling staining was used to detect apoptosis. Immunoblot analysis was performed to assess mTORC1/2 activity using p-Akt, p-S6, and p-4E-BP1. The expression of the antiapoptotic protein Bcl-2, pro-apoptotic protein Bax, and the mediator of angiogenesis vascular endothelial growth factor were also investigated.', 'The mean tumor volume of PP242 was significantly lower than in other groups. The terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling results showed that PP242 markedly increased cell apoptosis compared with other groups. Immunoblot analysis of tumor lysates treated with PP242 demonstrated inhibition of activated p-Akt. We also observed that only PP242, but not rapamycin, significantly reduced Bcl-2 expression and markedly increased Bax expression. Rapamycin decreased vascular endothelial growth factor expression, but not nearly as striking as seen in the PP242 group.

Input: Consider Input: Collagenous colitis (CC) is a major cause of chronic non-bloody diarrhoea, particularly in the elderly female population. The aetiology of CC is unknown, and still poor is the understanding of its pathogenesis. This possibly involves dysregulated inflammation and immune-mediated reactions in genetically predisposed individuals, but the contribution of genetic factors to CC is underinvestigated. We systematically tested immune-related genes known to impact the risk of several autoimmune diseases for their potential CC-predisposing role.', 'Three independent cohorts of histologically confirmed CC cases (N=314) and controls (N=4299) from Sweden and Germany were included in a 2-step association analysis. Immunochip and targeted single nucleotide polymorphism (SNP) genotype data were produced, respectively, for discovery and replication purposes. Classical human leucocyte antigen (HLA) variants at 2-digit and 4-digit resolution were obtained via imputation from single marker genotypes. SNPs and HLA variants passing quality control filters were tested for association with CC with logistic regression adjusting for age, sex and country of origin.', 'Forty-two markers gave rise to genome-wide significant association signals, all contained within the HLA region on chromosome 6 (best p=4.210
