Accumulating evidence has revealed that the expression of the lipid raft protein flotillin-1 is elevated in various human cancers, but the role flotillin-1 plays in the carcinogenesis of cervical cancer remains unclear. The expression profile of flotillin-1 was assayed using real-time PCR, western blotting, and immunohistochemical (IHC) staining in cervical cancer cell lines and cancer tissues with paired adjacent noncancerous cervical tissues. The expression of flotillin-1 protein was detected by IHC staining in a large cohort of 308 paraffin-embedded cervical cancer tissues.

In this manuscript, we present a simple route to enhance upconversion (UC) emission by producing two different coordination sites of trivalent cations in a matrix material and adjusting crystal field asymmetry by Hf(4+) co-doping. A cubic phase, Y3.2Al0.

Article Synopsis
  • Current guidelines define HER2-positive tumors based on gene copy numbers, but these can be confusing in cases with additional copies of chromosome 17, known as polysomy 17.
  • A study analyzed 384 invasive breast cancer cases to evaluate how polysomy 17 affects HER2 testing results, finding 13.8% of cases exhibited this polysomy.
  • The research indicated that polysomy 17 does not reliably indicate HER2 positivity and can lead to unclear testing results, suggesting it shouldn't be used as an independent factor for gene amplification or protein overexpression.
