Description
The proper mammalian oocytes maturation is recognized as reaching MII stage and accumulation of mRNA and proteins in cell cytoplasm following fertilization. The proper course of folliculogenesis and oogenesis is orchestrated with morphogenesis significantly influencing further zygote formation and embryos growth. This study was aimed to determinate new transcriptomic markers of porcine oocytes morphogenesis associated with cell maturation capacity.

Description
We compare the performance of two library preparation protocols (poly(A) and exome capture) in in vitro degraded RNA samples Overall design: VcaP cell were grown, and treated with MDV3100 (enzalutamide) or DHT (dihydrotestosterone), intact RNA was isolated and samples were prepared in technical triplicates using two library preparation protocol. Also cells were subject to in vitro degradation through incubation of the whole cell lysate in 37C for increasing amounts of time. Following incbation paired capture and poly(A) libraries were prepared.

Description
NK cells are believed to contribute to the control of hepatitis C virus infection and pathogenesis of liver disease. Standard treatment of both acute and chronic hepatitis C is based on the administration of interferon alpha, however, the effects of type I interferons on human NK cells have not been studied in the context of hepatitis C. We therefore first performed a microarray screen for genes differentially regulated in human NK cells after stimulation of PBMC with recombinant interferon alpha-2b. One of the genes upregulated was TRAIL which was confirmed in vitro on the protein level.

Description
Mucinous tubular and spindle cell carcinoma (MTSCC) is a relatively rare subtype of renal cell carcinoma with distinctive morphologic and cytogenetic features. Here we carry out whole exome and transcriptome sequencing of a multi-institutional cohort of MTSCC (n=22). We demonstrate the presence of either biallelic loss of Hippo pathway tumor suppressor genes (TSGs) and/or evidence of alteration of Hippo pathway genes in 85% of samples. PTPN14 (31%) and NF2 (22%) were the most commonly implicated Hippo pathway genes while other genes such as SAV1 and HIPK2 were also involved in a mutually exclusive fashion. Mutations in the context of recurrent chromosomal losses amounted to bi-allelic alterations in these TSGs. As a read-out of Hippo pathway inactivation, a majority of cases (90%) exhibited increased nuclear YAP1 protein expression. To identify transcriptional targets of the Hippo pathway in kidney we performed PTPN14 knockdown followed by RNA-seq in 2 kidney cancer cell lines (CAKI-1 and A-704) and a normal kidney epithelial cell line (HK-2). PTPN14 siRNAs were first functionally validated in a MCF-7 TEAD reporter luciferase stable cell line. Both siRNAs showed comparable knockdown efficiency and significantly increased luciferase reporter activity. In 2 of the kidney cell lines PTPN14 knockdown increased cell proliferation compared to non-target controls. While we observed excellent correlation between genes dysregulated by either PTPN14 or LATS1 knockdown within each cell line (HK2, CAKI-1 and A704), the overlap across the 3 cell lines was only 23 genes. Further, these 23 genes did not show concordant differential expression in MTSCC tumors. Overall, these results illustrate the marked tissue specificity of Hippo pathway targets.Finally, taken together, nearly all cases of MTSCC exhibit some evidence of Hippo pathway dysregulation. Overall design: Cell lines (CAKI-1, HK2 or A704) were either transfected with 2 independent siRNAs or non-target controls. Forty eight hours post transcription total RNA was isolated and subjected to RNA-seq analysis

Description
CD8+ T cells activated by cancer immunotherapy execute tumor clearance mainly by inducing cell death through perforin-granzyme- and Fas/Fas ligand-pathways. Ferroptosis is a form of cell death that differs from apoptosis and results from iron-dependent lipid peroxide accumulation. Although it was mechanistically illuminated in vitro, emerging evidence has shown that ferroptosis may be implicated in a variety of pathological scenarios. However, the involvement of ferroptosis in T cell immunity and cancer immunotherapy is unknown. Here, we find that immunotherapy-activated CD8+ T cells enhance ferroptosis-specific lipid peroxidation in tumor cells, and in turn, increased ferroptosis contributes to the anti-tumor efficacy of immunotherapy. Mechanistically, IFNg released from CD8+ T cells downregulates expression of SLC3A2 and SLC7A11, two subunits of glutamate-cystine antiporter system xc-, restrains tumor cell cystine uptake, and as a consequence, promotes tumor cell lipid peroxidation and ferroptosis. In preclinical models, depletion of cyst(e)ine by cyst(e)inase in combination with checkpoint blockade synergistically enhances T cell-mediated anti-tumor immunity and induces tumor cell ferroptosis. Thus, T cell-promoted tumor ferroptosis is a novel anti-tumor mechanism. Targeting tumor ferroptosis pathway constitutes a therapeutic approach in combination with checkpoint blockade. Overall design: Human HT-1080 mRNA profiles treated by IFNg for 8 hours was determined by RNA-Seq.

Description
Global gene expression profiling of the avian B-lymphoma DT40 cell line was used as a model to differentiate among Btk KO and Btk KO cells reconstituted with human Btk. Differences in the gene expression pattern showed statistically significant changes between parental DT40 and all the Btk KO cell populations irrespective of whether they are reconstituted or not. These results imply that in the process of generating a knockout cell line, subclones are selected, which have multiple changes in their gene expression pattern (p<0.01).

Description
Hepatocellular carcinoma (HCC) accounts for the majority of malignant liver tumors and results in many deaths each year, emphasizing the need for new therapies. The protein-protein interaction between menin and histone methyltransferase Mixed Lineage Leukemia 1 (MLL1) plays an important role in the development of HCC, implying that pharmacologic inhibition of this interaction could lead to new therapeutic strategy for the HCC patients. Therefore, we performed RNA sequencing experiment to determine the transcriptome change in the HepG2 cells upon treatment of MI-503, a small molecule inhibitor of the menin-MLL1 interaction with optimized drug-like properties Overall design: HepG2 cells were plated in the 12-well plates at the initial concentration of 0.4x106 cells/ml and treated with 3 µM MI-503 or DMSO (0.25%) in triplicates. After 3 days of treatment viable cell number was adjusted to the original concentration in the DMSO treated samples and the same dilution factor was used to adjust cell number in the MI-503 treated cells. Media was changed and compound or DMSO was re-supplied at that time. Cells were harvested after 3 more days of incubation.
