Multifunctional Chitosan-45S5 Bioactive Glass-Poly(3-hydroxybutyrate-<i>co</i>-3-hydroxyvalerate) Microsphere Composite Membranes for Guided Tissue/Bone Regeneration
Novel multifunctional chitosan-45S5
bioactive glass-polyÂ(3-hydroxybutyrate-<i>co</i>-3-hydroxyvalerate)
(PHBV) microsphere (CS-BG-MS) composite
membranes were developed with applicability in guided tissue/bone
regeneration (GTR/GBR). The incorporation of 45S5 BG and PHBV MS into
CS membranes not only provided the membranes with favorable surface
roughness, hydrophilicity, and flexibility but also slowed down their
degradation rate. Moreover, the CS membranes became bioactive after
the incorporation of 45S5 BG and capable of releasing drugs of different
physicochemical properties in a controlled and sustained manner with
the addition of PHBV MS. Cell culture tests showed that osteoblast-like
MG-63 human osteosarcoma cells had significantly higher adhesion,
cell proliferation, and alkaline phosphatase (ALP) activity on CS-BG
and CS-BG-MS membranes than on neat CS membranes. Therefore, the developed
bioactive CS-BG-MS membranes with potential multidrug (e.g., antibacterial
and antiosteoporosis drugs) delivery capability are promising candidate
membranes for GTR/GBR applications

<i>CF</i><sub><i>2</i></sub><i>–II</i> Alternative Splicing Isoform Regulates the Expression of Xenobiotic Tolerance-Related Cytochrome P450 <i>CYP6CY22</i> in <i>Aphis gossypii</i> Glover
The expression of P450 genes is regulated by trans-regulatory factors or cis-regulatory
elements and
influences how endogenous or xenobiotic substances are metabolized
in an organism’s tissues. In this study, we showed that overexpression
of the cytochrome P450 gene, CYP6CY22, led to resistance
to cyantraniliprole in Aphis gossypii. The expression of CYP6CY22 increased in the midgut
and remaining carcass of the CyR strain, and after repressing the
expression of CYP6CY22, the mortality of cotton aphids
increased 2.08-fold after exposure to cyantraniliprole. Drosophila ectopically expressing CYP6CY22 exhibited tolerance
to cyantraniliprole and cross-tolerance to xanthotoxin, quercetin,
2-tridecanone, tannic acid, and nicotine. Moreover, transcription
factor CF2–II (XM_027994540.2) is transcribed only as the splicing variant isoform CF2–II-AS, which was found to be 504 nucleotides shorter than CF2–II in A. gossypii. RNAi and yeast one-hybrid (Y1H) results
indicated that CF2–II-AS positively regulates CYP6CY22 and binds to cis-acting element p (−851/-842)
of CYP6CY22 to regulate its overexpression. The above
results indicated that CYP6CY22 was regulated by
the splicing isoform CF2-II-AS, which will help us
further understand the mechanism of transcriptional adaption of cross-tolerance
between synthetic insecticides and plant secondary metabolites mediated
by P450s
