Example Input: Glioma tumour-initiating cells (GTICs) can originate upon the transformation of neural progenitor cells (NPCs). Studies on GTICs have focused on primary tumours from which GTICs could be isolated and the use of human embryonic material. Recently, the somatic genomic landscape of human gliomas has been reported. RTK (receptor tyrosine kinase) and p53 signalling were found dysregulated in 90% and 86% of all primary tumours analysed, respectively. Here we report on the use of human-induced pluripotent stem cells (hiPSCs) for modelling gliomagenesis. Dysregulation of RTK and p53 signalling in hiPSC-derived NPCs (iNPCs) recapitulates GTIC properties in vitro. In vivo transplantation of transformed iNPCs leads to highly aggressive tumours containing undifferentiated stem cells and their differentiated derivatives. Metabolic modulation compromises GTIC viability. Last, screening of 101 anti-cancer compounds identifies three molecules specifically targeting transformed iNPCs and primary GTICs. Together, our results highlight the potential of hiPSCs for studying human tumourigenesis.
Example Output: Establishment of human iPSC-based models for the study and targeting of glioma initiating cells

Example Input: Brown adipocytes dissipate energy, whereas white adipocytes are an energy storage site. We explored the plasticity of different white adipose tissue depots in acquiring a brown phenotype by cold exposure. By comparing cold-induced genes in white fat to those enriched in brown compared with white fat, at thermoneutrality we defined a "brite" transcription signature. We identified the genes, pathways, and promoter regulatory motifs associated with "browning," as these represent novel targets for understanding this process. For example, neuregulin 4 was more highly expressed in brown adipose tissue and upregulated in white fat upon cold exposure, and cell studies showed that it is a neurite outgrowth-promoting adipokine, indicative of a role in increasing adipose tissue innervation in response to cold. A cell culture system that allows us to reproduce the differential properties of the discrete adipose depots was developed to study depot-specific differences at an in vitro level. The key transcriptional events underpinning white adipose tissue to brown transition are important, as they represent an attractive proposition to overcome the detrimental effects associated with metabolic disorders, including obesity and type 2 diabetes.
Example Output: Brown and white adipose tissues: intrinsic differences in gene expression and response to cold exposure in mice

Example Input: Lung cancer is the leading cause of cancer related deaths accounting for more deaths than breast, colon and prostate cancers combined. The Rb-p16 regulatory pathway plays an essential role in tumor suppression in the lung epithelium. This is evidenced by the nearly universal alterations in Rb-p16 pathway components in lung cancer, and the increased incidence of pulmonary carcinomas in persons with germline Rb mutations. Interestingly, p16 loss and Rb mutations preferentially occur in phenotypically distinct lung cancer subtypes. Analysis of human tumors has identified progressive preneoplastic lesions that accumulate molecular alterations in an orderly sequence. Epigenetic p16 gene modifications represent an early event in lung cancer progression. This review summarizes the human studies that demonstrate a critical role for the Rb-p16 tumor suppressor pathway in lung carcinogenesis, and discusses how these findings in combination with genetically engineered mouse models have significantly contributed to our understanding of lung cancer pathogenesis.
Example Output:
Retinoblastoma regulatory pathway in lung cancer.
