Chemical manipulations performed on the histone H3 lysine 9 methyltransferases (G9a/GLP) inhibitor BIX-01294 afforded novel desmethoxyquinazolines able to inhibit the DNA methyltransferase DNMT3A at low micromolar levels without any significant inhibition of DNMT1 and G9a. In KG-1 cells such compounds, when tested at sub-toxic doses, induced the luciferase re-expression in a stable construct controlled by a cytomegalovirus (CMV) promoter silenced by methylation (CMV-luc assay). Finally, in human lymphoma U-937 and RAJI cells, the N-(1-benzylpiperidin-4-yl)-2-(4-phenylpiperazin-1-yl)quinazolin-4-amine induced the highest proliferation arrest and cell death induction starting from 10 µM, in agreement with its DNMT3A inhibitory potency.

Scientific studies in many areas of biology routinely employ evolutionary analyses based on inference of phylogenetic trees from molecular sequence data. Evolutionary processes that act at the molecular level are highly variable, and properly accounting for heterogeneity is crucial for more accurate phylogenetic inference. Nucleotide substitution rates and patterns are known to vary among sites in multiple sequence alignments, and such variation can be modeled by partitioning alignments into categories corresponding to different substitution models.

Raine syndrome (RNS) is an autosomal recessive neonatal osteosclerotic bone dysplasia that usually results in death in the postnatal period. Patients present with abnormal craniofacial features and widespread periosteal osteosclerosis affecting the ribs, skull, and long bones. Nonlethal forms of RNS have recently been reported.

Background/objectives: Neural tube defects (NTDs) are congenital malformations arising when the neural tube (NT), precursor of the brain and spine, fails to properly close during neurulation. Etiology is multifactorial, with environmental and genetic factors variably contributing on a case-by-case basis. Molecular genetic studies of murine NTD genes have been precious in the identification of predisposing NTD genes in humans, highlighting the peculiar role of the planar cell polarity (PCP) pathway in a fraction of human NTD patients.

A properly optimized concrete mix design yields the required workability and strength for the fresh and hardened concrete to sustain desired loads and stresses over time, preventing premature failure. Thus, it is imperative to investigate the behavioural sensitivity of blended cement concrete to mix design variations. The research uses the Box-Behnken design of the response surface method to optimize the slump and compressive strength of blended cement concrete incorporating Shea nutshell ash (SNA).
