PNAS: Interaction between microRNAs and actin-associated protein Arpc5 regulates translational suppression during male germ cell differentiation

April 10, 2012

Yao-Fu Chang, Jennifer S. Lee-Chang, J. Saadi Imam, Kalyan Chakravarthy Buddavarapu, Sarah S. Subaran, Amiya P. Sinha-Hikim, Myriam Gorospe, and Manjeet K. Rao Abstract Decoupling of transcription and translation during postmeiotic germ cell differentiation is critical for successful spermatogenesis. Here we establish that the interaction between microRNAs and actin-associated protein Arpc5 sets the stage for an elaborate translational control mechanism by facilitating […]

Human Reproduction: Parental infertility, infertility treatment and hepatoblastoma: a report from the Children’s Oncology Group

April 3, 2012

Susan E Puumala 1, Julie A Ross, James H Feusner, Gail E Tomlinson, Marcio H Malogolowkin, Mark D Krailo, Logan G Spector Abstract Background: A recent study suggested a markedly increased risk of hepatoblastoma (HB) among children conceived with treatment for infertility. However, it is not clear whether this finding is confounded by the association between HB and low birth weight (LBW). Methods: Associations […]

Molecular Biology of the Cell: Attenuation of TGF-β signaling suppresses premature senescence in a p21-dependent manner and promotes oncogenic Ras-mediated metastatic transformation in human mammary epithelial cells

February 22, 2012

Shu Lin 1, Junhua Yang, Abdel G Elkahloun, Abhik Bandyopadhyay, Long Wang, John E Cornell, I-Tien Yeh, Joseph Agyin, Gail Tomlinson, Lu-Zhe Sun Abstract The molecular mechanisms that drive triple-negative, basal-like breast cancer progression are elusive. Few molecular targets have been identified for the prevention or treatment of this disease. Here we developed a series of isogenic basal-like human mammary epithelial cells (HMECs) with altered […]

Gastroenterology: Integrative Genomic Identification of Genes on 8p Associated With Hepatocellular Carcinoma Progression and Patient Survival

December 3, 2011

Background & Aims Hepatocellular carcinoma (HCC) is an aggressive malignancy; its mechanisms of development and progression are poorly understood. We used an integrative approach to identify HCC driver genes, defined as genes whose copy numbers associate with gene expression and cancer progression.

Stand Genomic Sciences: Minimum Information about a Genotyping Experiment (MIGEN)

November 30, 2011

Jie Huang, Daniel Mirel, Elizabeth Pugh, Chao Xing, Peter N Robinson, Alexander Pertsemlidis, Lianghao Ding, Julia Kozlitina, Joseph Maher, Jonathan Rios, Michael Story, Nishanth Marthandan, Richard H Scheuermann Abstract Genotyping experiments are widely used in clinical and basic research laboratories to identify associations between genetic variations and normal/abnormal phenotypes. Genotyping assay techniques vary from single genomic regions that are interrogated using PCR reactions to high throughput assays […]

Breast Cancer Research: Common breast cancer susceptibility alleles are associated with tumour subtypes in BRCA1 and BRCA2 mutation carriers: results from the Consortium of Investigators of Modifiers of BRCA1/2

Biotechniques: Isolation of Sertoli, Leydig, and spermatogenic cells from the mouse testis

November 5, 2011

Yao-Fu Chang 1, Jennifer S Lee-Chang, Subbarayalu Panneerdoss, James A MacLean 2nd, Manjeet K Rao Abstract A thorough understanding of the events during mammalian spermatogenesis requires studying specific molecular signatures of individual testicular cell populations as well as their interaction in co-cultures. However, most purification techniques to isolate specific testicular cell populations are time-consuming, require large numbers of animals, and/or […]

Journal of Biological Chemistry: Mutant p53 Disrupts Role of ShcA Protein in Balancing Smad Protein-dependent and -independent Signaling Activity of Transforming Growth Factor-β (TGF-β)*

October 26, 2011

Shu Lin‡, Lan Yu‡, Junhua Yang‡, Zhao Liu‡, Bijal Karia‡§, Alexander J. R. Bishop‡§¶, James Jackson‖, Guillermina Lozano‖, John A. Copland**, Xiaoxin Mu‡‡‡, Beicheng Sun‡‡ and Lu-Zhe Sun‡¶,1 Abstract Biomarkers are lacking for identifying the switch of transforming growth factor-β (TGF-β) from tumor-suppressing to tumor-promoting. Mutated p53 (mp53) has been suggested to switch TGF-β to a tumor promoter. However, we found that mp53 does not always promote […]
