Article Synopsis
- The study investigates how changes in the Ki67 biomarker before and after neoadjuvant chemotherapy (NACT) affect survival in patients with triple-negative breast cancer (TNBC).
- Among 1,777 TNBC patients analyzed, most showed a decrease in tumor size and Ki67 levels after NACT, though many had no change or experienced treatment discontinuation.
- Patients with unchanged Ki67 had significantly worse overall and disease-specific survival compared to those with decreased Ki67, emphasizing the need for personalized treatment strategies based on ongoing monitoring of this biomarker.
Elevated MRPS23 expression facilitates aggressive phenotypes in breast cancer cells.

Mitochondrial ribosomal protein S23 (MRPS23), encoded by a nuclear gene, is a well-known driver of proliferation in cancer. It participates in mitochondrial protein translation, and its expression association has been explored in many types of cancer. However, MRPS23 expression associations are rarely reported in breast cancer (BC).

Berberine (BBR), an isoquinoline alkaloid abundant in Coptis chinensis, exhibits anti-tumor and hypoglycemic properties. The regulation of tumor cell homeostasis and metabolism is greatly influenced by Hypoxia-inducible factor-1α (HIF-1α). This research aims to elucidate whether BBR inhibits the progression of hepatocellular carcinoma (HCC) by modulating HIF-1α expression.

In this paper, we investigated the interactions between ATL-I and Keratin 7 (KRT7), a CRC-specific marker, to determine the potential pathways by which ATL-I inhibits CRC development. The KRT7 expression level in CRC was predicted online using the GEPIA website and then validated.

Objective To investigate the effect of basic helix-loop-helix family member E40 (BHLHE40) on the invasion and migration of osteosarcoma (OS) cells, and to explore the role of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway in the biological behavior of OS mediated by BHLHE40, providing a scientific basis for targeted therapy of OS. Methods On the basis of clinical OS samples and OS cell lines, the expression differences of BHLHE40 between OS and adjacent tissues, as well as those between OS cells and normal osteoblast cell lines, were analyzed. BHLHE40 knockdown OS cells were obtained through shRNA transfection.
