Preparation of doxorubicin-loaded porous iron Oxide@ polydopamine nanocomposites for MR imaging and synergistic photothermal-chemotherapy of cancer.

Recently, the development of biosafe nanocomposites with integrated diagnosis and therapeutic modality is received great attention in anti-cancer drug delivery. In this sturdy, we developed a multifunctional PION@PDA-PEG nanocomposite that combines the functions of magnetic resonance (MR) imaging, photothermal therapy (PTT) and chemotherapy into one single nanoprobe. The spherical and uniform-sized porous iron oxide nanoparticles (PION) were synthesized via a simple solvothermal method.

LncRNA HOXD-AS1 promotes epithelial ovarian cancer cells proliferation and invasion by targeting miR-133a-3p and activating Wnt/β-catenin signaling pathway.

Background: Long non-coding RNA (lncRNA) HOXD cluster antisense RNA 1 (HOXD-AS1) functions as a crucial regulator in the progression and development of tumors. The aim of this study is to unravel the underlying mechanisms of HOXD-AS1 on epithelial ovarian cancer (EOC).

Methods: 43 paired EOC tissues and adjacent non-tumor tissues were collected postoperatively from patients.
