Nanog is a pluripotency-related factor. It was also found to play an important role in tumorigenesis. To date, the mechanisms underlying cervical tumorigenesis still need to be elucidated. In the present study, Nanog mRNA was synthesized in vitro and transfected into HeLa cells. After mRNA transfection, the forced expressed of Nanog in HeLa cells led to markedly increased invasion, migration, resistance to chemotherapeutic agents and dedifferentiation. In a subcutaneous xenograft assay, these cells had significantly increased tumorigenic capacity. Real-time PCR indicated that Nanog‑induced dedifferentiation was associated with increased expression of endogenous Oct4, Sox2 and FoxD3. In addition, the dedifferentiated HeLa cells acquired features associated with cancer stem cells (CSCs), such as multipotent differentiation capacity, and expression of CSC markers such as CD133. These data imply that Nanog is a positive regulator of cervical cancer dedifferentiation.

Hen eggs are rich in proteins, which are a potential source of bioactive peptides. Incubation of fertilized egg changes the egg protein, which may affect the properties and activity of derived peptides. To understand these metamorphoses, hydrolysate fractions of 10-day incubated chicken embryo (CE) proteins of 0.

Copy number control of DNA and centrosomes is essential for accurate genetic inheritance. DNA replication and centrosome duplication have been recognized as parallel key events for cell division. Here, we discover that the DNA replication machinery directly regulates the licensing and execution processes of centrosome duplication to prevent centrosome amplification.

Mitochondria continually undergo fission to maintain their network and health. Nascent fission sites are marked by the ER, which facilitates actin polymerization to drive calcium flux into the mitochondrion and constrict the inner mitochondrial membrane. Septins are a major eukaryotic cytoskeleton component that forms filaments that can both directly and indirectly modulate other cytoskeleton components, including actin.

Background: Hyperthermia (HT), while a cancer treatment approach, isn't always effective alone. Therefore, identifying hyperthermia enhancers is crucial. We demonstrated that Mito-TEMPO ([2-[(1-Hydroxy-2,2,6,6-tetramethylpiperidin-4-yl) amino]-2-oxoethyl]-triphenylphosphanium, MT) acts as a potent thermosensitizer, promoting cell death in human cervical cancer (HeLa) cells.

Background: Hexavalent chromium ions (Cr(VI)), a notorious toxic heavy metal pollutant with proven carcinogenicity, endangers human health and the environment. Meanwhile, l-ascorbic acid (L-AA), a vital biological antioxidant, has abnormal levels closely tied to various diseases. Developing efficient synchronous detection methods for these two key analytes is of great value in clinical and environmental monitoring.
