Abstract Accumulating evidence has indicated that long non-coding RNAs (lncRNAs) play critical roles in the development and progression of cancers, including esophageal squamous cell carcinoma (ESCC). However, the mechanisms of lncRNAs in ESCC are still incompletely understood and therapeutic attempts for in vivo targeting cancer-associated lncRNA remain a challenge. By RNA-sequencing analysis, we identified that LLNLR-299G3.1 was a novel ESCC-associated lncRNA. LLNLR-299G3.1 was up-regulated in ESCC tissues and cells and promoted ESCC cell proliferation and invasion. Silencing of LLNLR-299G3.1 with ASO (antisense oligonucleotide) resulted in opposite effects. Mechanistically, LLNLR-299G3.1 bound to cancer-associated RNA binding proteins and regulated the expression… More >

Abstract The rye genome has shown potential for improvement of bread wheat, where wheat-rye substitutions and translocations have been and are frequently used in resistance breeding. Crosses belongs to different generations viz., BC₁F₁, BC₁F₂, BC₁F₃, BC₁F₄ and BC₂F₃ of triticale × wheat derived were used for different haploid induction parameters using Gogon grass (Imperata cylindrica) as a pollen source. The percentage of pseudo seed formation ranged from 34.55% for BC₁F₂ to 63.77 for BC₁F₁ crosses, the haploid embryo formation ranges from 9.43% for BC₁F₁ to 30.2% for BC₁F₂, the haploid plant generation ranges from 19.36% for BC₁F₂ to 63.25% for BC₁F₁.

Abstract Stem cells constitute the source of cells that replenishes the worn out or damaged cells in our tissue and enable the tissue to carry out the destined function. Tissue-specific stem cells are compartmentalized in a niche, which keeps the stem cells under quiescent condition. Thus, understanding the molecular events driving the successful differentiation of stem cells into several lineages is essential for its better manipulation of human applications. Given the developmental aspects of the cell, the cellular function is greatly dependent on the epigenomics signature that in turn governs the expression profile of the cell.… More >

Abstract Polyembryony in maize (PEm) contributes to improving the nutritional properties of the grain, as well as an increase in yield, since it generates multiple plants per seed, opening the possibility of developing new varieties. However, it is unknown whether polyembryony in maize is the product of chromosomal abnormalities. Based on the above, in this research a cytogenetic study was proposed to verify if chromosomal abnormalities are related to the maize polyembryony. For a meiotic study, maize genotypes with variable proportions of polyembryony (PEm), from the UA-IMM-BAP population and non-PEm (monoembryonic) maize were used, while for… More >

Abstract The dramatic re-organization of chromatin during mitosis is perhaps one of the most fundamental of all cell processes [1,2]. It remains unclear how epigenetic histone modifications, despite their crucial roles in regulating chromatin architectures, are dynamically coordinated with chromatin reorganization in controlling this process. Mechanical cues have also been shown to play important roles in modulating gene expressions and cellular functions [3,4]; however, it is still unclear about the mechanical regulations of epigenetics and chromatin organization. In this study, we have developed and characterized biosensors with high sensitivity and specificity based on fluorescence resonance energy… More >

Abstract CG 10-248 (3,4-dihydro-2,2-dimethyl-9-chloro-2H-naphtho[1,2b]pyran- 5,6-dione; CG-NQ), a β-lapachone analogue, modified the ultrastructure of rat hepatocytes, as demonstrated by light and electron microscopy. After 4 h incubation with 100 µM CG-NQ, the following effects were observed: (a) nuclear chromatin condensation; (b) chromatin fragmentation; (c) displacement of mitochondria, concentrated around the nucleus; (d) disruption or expansion of mitochondrial outer or inner membranes, respectively; (e) displacement and alteration of endoplasmic reticulum (rough and smooth); (f) decrease of microvilli; (g) blebbing of plasma membrane and production of apoptotic bodies formed by folding of plasma membrane fragments around mitochondria or peroxysomes; More >
