Abstract: Several embryonic cellular mechanism including cell
cycle, growth and apoptosis are regulated by phosphatidylinositol-3-
kinase (PI3K)/Akt signaling pathway. The goal of present study is to
determine the effects of annatto (Bixa orellana)-derived δ-tocotrienol
(δ-TCT) on the regulations of PI3K/Akt genes in murine morula.
Twenty four 6-8 week old (23-25g) female balb/c mice were
randomly divided into four groups (G1-G4; n=6). Those groups were
subjected to the following treatments for 7 consecutive days: G1
(control) received tocopherol stripped corn oil, G2 was given 60
mg/kg/day of δ-TCT mixture (contains 90% delta & 10% gamma
isomers), G3 was given 60 mg/kg/day of pure δ-TCT (>98% purity)
and G4 received 60 mg/kg/day α-TOC. On Day 8, females were
superovulated with 5 IU Pregnant Mare’s Serum Gonadotropin
(PMSG) for 48 hours followed with 5 IU human Chorionic
Gonadotropin (hCG) before mated with males at the ratio of 1:1.
Females were sacrificed by cervical dislocation for embryo collection
48 hours post-coitum. About fifty morulas from each group were
used in the gene expression analyses using Affymetrix QuantiGene
Plex 2.0 Assay. Present data showed a significant increase (p
Abstract: Article devoted to the development of technologies
for medicine and agroecology by using plant organelle – spherosome.
Technological method of purification and isolation of this organelle
by using novel nanostructured carbon sorbent – “nanocarbosorb"
ARK type are presented. Also the methods of preparation of
nanocontainers based on using of spherosome with loaded isosorbide
dinitrate, piroxicam or diclofenak are exhibited. We found that the
spherosome could be applied for ecological aims as bioregulator and
also as biosensor for determination of ammonia ions in water
reservoirs at concentration range 1mM to 100mM.
