Description
We observed that mutations in CBP60a, CML46, CML47 and WRKY70 enhanced plant resistance to Pma likely through different mechanisms. To investigate their contributions to enhanced resistance at the transcriptome level, we designed this experiment to measure their response to Pma using the SMART-3Seq method. Overall design: Mature leaves of Arabidopsis plants of seven different genotypes were infiltrated with mock or Pma. Samples were collected 24 hours after treatment. Each experiment contains one sample consisted of two leaves for each genotype-treatment combination. In total three independent experiments were conducted.

Description
We observed inhibition of the hypersensitive response (a typical ETI response) by PTI signaling in an Arabidopsis quadruple mutant dde2 ein2 pad4 sid2 (quad). Thus, we designed an experiment to see the interaction between ETI and PTI signaling at the transcriptome level. The Arabidopsis line dde2 ein2 pad4 sid2 Ed-AvrRpt2 (quadAvrRpt2) was used (Ed-AvrRpt2, estradiol-inducible AvrRpt2 transgene). In this plant line, ETI can be elicited by estradiol (Ed) treatment via in planta expression of AvrRpt2. Transcriptome responses to PTI only, ETI only, and PTI+ETI together were recorded. Overall design: quadAvrRpt2 was treated with one of (1) Mock, (2) flg22 to elicit PTI response only, (3) Ed to elicit ETI response only via AvrRpt2, (4) flg22+Ed to elicit both PTI and ETI responses together. At 0 (untouched), 60, 120, 180, and 300 minutes after treatment, treated plant leaves were harvested for RNA-seq analysis. Three independent experiments were performed (rep1-rep3).

Description
Injuries to the anterior cruciate ligament (ACL) often result in post-traumatic osteoarthritis (PTOA). PTOA accounts for ~12% of all osteoarthritis (OA) cases, yet the mechanisms contributing to OA after joint injury are not well understood. To better understand the molecular mechanisms behind PTOA development following ACL injury, we profiled ACL injury-induced gene expression changes in knee joints of three mouse strains with varying susceptibility to PTOA: STR/ort (highly susceptible), C57BL/6 (moderately susceptible) and super-healer MRL/MpJ (not susceptible) and identified genes differentially expressed between these strains at 0-day [before injury], 1-day, 1-week, and 2-weeks post-injury. This study highlights many new potential therapeutic targets and OA biomarkers. Overall design: Comparative transcriptomics to understand the molecular changes associated with early stages of PTOA development in STR/ort, C57BL/6 and MRL/MpJ mice and to identify genes that contribute to increased OA susceptibility in STR/ort and resistance to PTOA in MRL/MpJ.

Description
The canonical Wnt pathway plays a central role in stem cell maintenance, differentiation and proliferation in the intestinal epithelium. Constitutive, aberrant activity of the TCF4/ß-catenin transcriptional complex is the primary transforming factor in colorectal cancer. Despite significant recent inroads, the full complement of Wnt target genes and the mechanisms of regulation remain incompletely understood. Here we identify a nuclear long non-coding RNA, termed WiNTRLINC1, as a direct target of TCF4/ß-catenin in colorectal cancer cells. WiNTRLINC1 positively regulates the expression of its close neighbor ASCL2, a transcription factor that controls intestinal stem cell fate. WiNTRLINC1 interacts with TCF4/ß-catenin to mediate the juxtaposition/physical contact of its own promoter with the regulatory regions of ASCL2. ASCL2, in turn, regulates WiNTRLINC1 expression. This feedforward regulatory loop controls stem cell-related gene expression and is highly amplified in colorectal cancer. Overall design: Derivatives of Ls174T colon cancer cells, overexpressing the Tet repressor were used for the construction of inducible overexpressing a shRNA against the WiNTRLINC1 long non coding RNA upon treatment with doxyxycline. siRNAs against WiNTRLINC1 were designed with the siDesign center tool from Dharmacon and their sequences were used for the construction of the shRNA stem loop structure as described in EMBO Rep. 2003 Jun;4(6):609-15. The modified pTER vector was used as a backbone for constructing the shRNA cassette as described in EMBO Rep. 2003 Jun;4(6):609-15. Positive cell clones were screened with RT-PCR in order to validate the efficiency of the knockdown of WiNTRLINC1. The Ls174T derivative cell line inducibly overexpressing a shRNA against ASCL2 has been described previously in Cell. 2009 Mar 6;136(5):903-12. RNA deep sequencing was performed in the WiNTRLINC1 KD and ASCL2 KD cells compared to controls cells in order to detect changes in gene expression due to the loss of either WiNTRLINC1 or ASCL2.

Description
Hepatic fibrosis is a wound-healing response to chronic liver injury, which may result in cirrhosis and liver failure. The c-Jun N-terminal kinase-1 (JNK1) gene has been shown to be involved in liver fibrosis. Here, we aimed to investigate the molecular mechanism and identify the cell-type involved in mediating the JNK1-dependent effect on liver fibrogenesis Wild-type (WT), JNK1/ and JNK1hepa (hepatocyte-specific deletion of JNK1) mice were subjected to bile duct ligation (BDL). Additionally, we performed bone marrow transplantations (BMT), isolated primary hepatic stellate cells (HSCs) and studied their activation in vitro. Serum markers of liver damage (liver transaminases, alkaline phosphatase and bilirubin) and liver histology revealed reduced injury in JNK1/ compared to WT and JNK1hepa mice. Hepatocyte cell death and proliferation was reduced in JNK1/ compared to WT and JNK1hepa. Parameters of liver fibrosis such as Sirius Red staining as well as Collagen IA1 and SMA expression were down-regulated in JNK1/ compared to WT and JNK1hepa livers, 4 weeks after BDL. To delineate the essential cell-type, we performed BMT of WT and JNK1-/- into JNK1-/- and WT mice, respectively. BMT experiments excluded bone marrow derived cells from having a major impact on the JNK1-dependent effect on fibrogenesis. Hence, we investigated primary HSCs from JNK1/ livers showing reduced transdifferentiation compared with WT and JNK1hepa-derived HSCs. We conclude that JNK1 in HSCs plays a crucial role in hepatic fibrogenesis and thus represents a promising target for cell-directed treatment options for liver fibrosis.
