The Clinical Application Value of RDW, CA153, and MPV in Breast Cancer.

BACKGROUND: Early detection of tumors is beneficial to the treatment of patients. Certain indicators in the blood routine, such as red blood cell distribution width (RDW), are considered to be used to assess the patient's condition and prognosis. Mean platelet volume (MPV) is also used to assess the prognosis of patients. Carbohydrate antigen 153 (CA153) is considered to be a more specific antigen marker for breast cancer. The purpose of our study was to explore the diagnostic value of RDW, MPV, and CA153 for breast cancer (BC) and breast hyperplasia (BH). METHODS: The study included 104 breast cancer patients, 100 breast hyperplasia patients, and 100 healthy controls. CA153 was detected by an automatic electrochemical luminescence analyzer (Cobas e601, Roche Diagnostics, Switzerland). The concentration of RDW and MPV in serum was measured by Sysmex XN-10-B3 (Sysmex, Ja¬pan). RESULTS: Compared with the breast hyperplasia group, the RDW and CA153 of the breast cancer group were increased. The healthy control group, mammary gland hyperplasia group, and breast cancer were positively correlated with RDW and CA153. Logistic regression results show that increasing age, increasing RDW, and increasing CA153 can increase the risk of breast cancer. The area under the ROC (AUC) analysis showed that the combined specificity and sensitivity of the combined application of RDW, MPV, and CA153 for the identification of breast cancer is better than that of a single marker. CONCLUSIONS: The combined application of RDW, MPV, and CA153 can improve the differential diagnosis of breast cancer and breast hyperplasia.

Single-cell profiling reveals sex diversity in human renal proximal tubules.

Many anatomical regions in the kidney, including proximal tubules, differ between males and females. While such differences in renal structures and functions under various physiological and pharmacological conditions have been identified, information relating to molecular mechanisms behind this gender disparity remain unknown. To understand gene expression differences in proximal tubules from human male and female kidneys, we reported on kidney cellular landscape using single-cell RNA sequencing. Differential gene expression profiles were observed in proximal tubules, between the sexes. Interestingly, the SLC22 family of anion transporters, including SLC22A6 and SLC22A8, had different expression profiles between male and female proximal tubule clusters but not sex-dependent abundance at the protein level. Moreover, in different species, we revealed a shared and species-specific differential gene expression between human and mouse kidney proximal tubules. Taken together, at single-cell resolution, this transcriptomic map represents a baseline description of gender biased genes in human kidney proximal tubules, which provide important insights for further studies of physiological differences in kidney.
