Potentiality of raloxifene loaded melittin functionalized lipidic nanovesicles against pancreatic cancer cells.

Pancreatic cancer (PC) frequency and incidence have grown rapidly in recent years. One of the most serious problems with PC is the existence of asymptotic manifestations, which frequently delays early detection, and until the diagnosis is established, tumor cells progress to the metastatic stage. Another significant concern with PC is the scarcity of well-defined pharmacotherapeutic drugs.

Augmentation of Antidiabetic Activity of Glibenclamide Microspheres Using S-Protected Okra Powered by QbD: Scintigraphy and In Vivo Studies.

Successful drug delivery by mucoadhesive systems depends on the polymer type, which usually gets adherent on hydration. The intended polymers must sustain the association with biomembranes and preserve or accommodate the drug for an extended time. The majority of hydrophilic polymers tend to make weak interactions like noncovalent bonds, which hampers the positioning of dosage forms at the required target sites, leading to inefficient therapeutic outcomes.

Essential role of STAT-3 dependent NF-κB activation on IL-6-mediated downregulation of hepatic transporters.

IL-6 markedly decreases the expression of numerous hepatic transporters. We previously demonstrated that IL-6-mediated downregulation of transporters occurs through STAT3, with partial involvement of PXR. However, while IL-6-mediated induction of STAT3 occurs rapidly, repression of transporter expression is not observed until 6 h post-treatment.

STAT3 is involved in IL-6-Mediated Downregulation of Hepatic Transporters in Mice.

Unlabelled: Interleukin (IL)-6 decreases hepatic expression of numerous transporters. Although IL-6 signaling occurs through STAT3, the extent of the involvement of the STAT3 signaling pathway has not been elucidated.

Purpose: Our objective was to investigate whether IL-6-mediated effects occur through STAT3, and whether PXR plays a role in this regulation.

Involvement of Nuclear Factor B, not Pregnane X Receptor, in Inflammation-Mediated Regulation of Hepatic Transporters.

Endotoxin-induced inflammation decreases the hepatic expression of several drug transporters, metabolizing enzymes, and nuclear transcription factors, including pregnane X receptor (PXR). As the nuclear factor B (NF-B) is a major mediator of inflammation, and reciprocal repression between NF-B and PXR signaling has been reported, the objective of this study was to examine whether NF-B directly regulates the expression of transporters or exerts its effect indirectly via PXR. PXR-deficient (-/-) or wild-type (+/+) male mice were dosed with the selective NF-B inhibitor PHA408 (40 mg/kg i.
