The 2021 Annual Review Issue of The Journal of Pathology contains 14 invited reviews on current research areas of particular importance in pathology. The subjects included here reflect the broad range of interests covered by the journal, including both basic and applied research fields but always with the aim of improving our understanding of human disease. This year, our reviews encompass the huge...
This study was comparison of MGMT and ERBB2 expression in human gliomas. RT-PCR method was used to determine the mRNA levels of MGMT and ErbB2 gene in 42 clinical glioma specimens,There was significant concordance between the expression of MGMT and ErbB2 (p < 0.01). MGMT and ErbB are highly remarkably related each other. The results suggest that there may be in relationship among MGMT and ErbB2...
Background Resistance to drug is a major cause of treatment failure in pediatric brain cancer. The multidrug resistance (MDR) phenotype can be mediated by the superfamily of adenosine triphosphate-binding cassette (ABC) transporters. The dynamics of expression of the MDR genes after exposure to chemotherapy, especially the comparison between pediatric brain tumors of different histology, is poorly...
In breast cancer treatment for many cases intrinsic or acquired resistance against available therapeutics leads to death. According to the present biological understanding, drug resistance is caused by molecular mechanisms in the complex network of proteins that regulate cell proliferation by activation of the estrogen receptor (ER), hereby allowing the cell to bypass the classical estrogen receptor...

The mechanisms responsible for the development of the taxol resistance phenotype are unclear, and are likely explained by multiple mechanisms. To understand the molecular changes associated with drug resistance more fully, a taxol-resistant subline, derived from the human ovarian cancer cell line SKOV-3, was established through selection by culture in incrementally increasing taxol concentrations...
