Endosperm is an absorptive structure that supports embryo development or seedling germination in angiosperms. The endosperm of cereals a main source food, feed, and industrial raw materials worldwide. However, the genetic networks regulate cell differentiation remain largely unclear. As first step toward characterizing these networks, we profiled mRNAs five major types differentiating four maternal compartments maize (Zea mays) kernel. Comparisons mRNA populations revealed diverged gene...
Metastases are the major cause of melanoma-related mortality. Previous studies implicating aberrant AKT signaling in human melanoma metastases led us to evaluate effect activated AKT1 expression non-metastatic BRAF(V600E)/Cdkn2a(Null) mouse melanomas vivo. Expression resulted highly metastatic with lung and brain 67% 17% our mice, respectively. Silencing PTEN cooperated AKT1, resulting decreased tumor latency development nearly 80% tumor-bearing mice. These data demonstrate that activation...
Significance In flowering plants, double fertilization gives rise to an embryo and the endosperm, absorptive storage structure that supports embryogenesis seedling germination. cereal grains, endosperm comprises a large proportion of mature seed, contains amounts carbohydrates proteins, is important source food, feed, industrial raw materials. This study provides comprehensive profile genes expressed in early developing maize. We also show how series temporal programs gene expression...
Many species of echinoderms, in all five extant classes, contain subcuticular bacterial symbionts (SCB). The role these extracellular and the nature relationship remain unclear. We have sequenced 16S rRNA genes from to determine their phylogenetic affinities. Symbionts an ophiuroid, Ophiactis balli, appear closely related bacteria within alpha group class Proteobacteria, including intracellular endosymbionts pathogens. SCB are clearly separate origin other documented major groups marine...
Potential anti-inflammatory and anticarcinogenic effects of aspirin (ASA) may be suitable for melanoma chemoprevention, but defining biomarkers in relevant target tissues is prerequisite to performing randomized controlled chemoprevention trials. We conducted open-label studies with ASA 53 human subjects melanocytic nevi at increased risk melanoma. In a pilot study, 12 received single dose (325 mg) ASA; metabolites salicylate, salicylurate, gentisic acid were detected plasma after 4–8 h,...
Abstract Aberrant activation of the PI3K–AKT pathway is common in many cancers, including melanoma, and AKT1, 2 3 (AKT1–3) are bona fide oncoprotein kinases with well-validated downstream effectors. However, efforts to pharmacologically inhibit AKT have proven be largely ineffective. In this study, we observed paradoxical effects following either pharmacologic or genetic inhibition AKT1–3 melanoma cells. Although pharmacological was without effect, silencing all three paralogs significantly...
<p>Supplementary Figure S2 shows the classification of MTG001 and MTG004. Immunoblotting MTG004 PDX-derived cell lines showed similar levels P-AKT (Ser473), total AKT, P-ERK (Thr202/Tyr204), ERK1/2, P-Ribosomal S6 Kinase (Ser235/236), Kinase. GAPDH was used as a loading control. The cells exhibited higher PTEN. Analysis RNA sequencing data demonstrated that both express wildtype PTEN.</p>
<p>Supplementary Figure S1 shows that pharmacological inhibition of AKT has little effect on melanoma cells. Cell confluency assay under inhibition. A375, HT144, SK-MEL28, WM793, MTG001, and MTG004 cells were largely resistant to inhibitors MK2206 (2.5 µM) GDC0068 (1µM) while SK-MEL 28 MTG001 sensitive PI3Kα by GDC0941 (P < 0.001). Error bars indicate standard error the mean triplicate wells.</p>
