PI3 expression predicts recurrence after chemotherapy with DNA-damaging drugs in gastric cancer. (PubMed, J Pathol)
We also found that PI3 overexpression promoted 5-fluorouracil/oxaliplatin/cisplatin resistance but not paclitaxel resistance.

Increase of KLK7, cytokeratin 5/6, and elafin expression in head and neck squamous cell carcinoma compared with lung squamous cell carcinoma. (PubMed, J Histotechnol)
All three proteins were found to evidence higher expression in head and neck squamous cell carcinoma as compared with that of squamous cell carcinoma of the lung. The differences in expression may help clinical differentiation between primary tumors of the lung from metastatic tumors to the lung from the oral/laryngeal cavities.

Elafin is related to immune infiltration and could predict the poor prognosis in ovarian cancer. (PubMed, Front Endocrinol (Lausanne))
The high elafin expression was associated with an unfavorable OS, while it also indicated better immunotherapy responses. Thus, the detection of elafin is beneficial to diagnosis and treatment selection.

Mitochondrial ribosomal small subunit (MRPS) MRPS23 protein-protein interaction reveals phosphorylation by CDK11-p58 affecting cell proliferation and knockdown of MRPS23 sensitizes breast cancer cells to CDK1 inhibitors. (PubMed, Mol Biol Rep)
In conclusion, phosphorylation of MRPS23 by mitotic kinases might potentially be involved in the proliferation of breast cancer cells. Furthermore, MRPS23 can be targeted for sensitizing the breast cancer cells to CDK1 inhibitors.

PSMA conjugated combinatorial liposomal formulation encapsulating genistein and plumbagin to induce apoptosis in prostate cancer cells. (PubMed, Colloids Surf B Biointerfaces)
The decrease in migration potential of cells and induced apoptosis established the observed anti-proliferative effect in prostate cancer cell lines. The discussed strategy of developing novel, non-toxic, and PSMA specific antibody conjugated liposomes carrying genistein and plumbagin drugs may also be used for encapsulating other drugs and inhibit the growth of different types of cancers.
