The mechanism by which these variants influence the stage and grade is but to become identified. On the other hand, this relation appears to become racial and cancer kind modified due to the fact a Polish analysis located that Ile462Val will not be linked with stage or grade of cervical cancer.52 Similarly, an Iranian breast cancer study showed noassociations with the variants with stage but with breast cancer grade.53 An additional study located that these variants are related with better drug response in breast cancer.54 Some studies studied CYP1A1 mRNA expression in breast cancer cell lines and its inhibition was linked with impaired proliferation and improve apoptosis.55 In our work, we didn’t do gene expression work, which is valuable to seek out any association amongst breast tissue CYP1A1 expression and breast cancer occurrence and its stage and grade. From clinical point of view, getting history of the drugs offered to these sufferers andIbrahem et alTable six.

(A) The nuclear expression of ER is visible under low energy field (lPF) microscopy. Higher energy field (HPF) view is shown at the correct reduce corner of the image. (B) PR is observed beneath lPF as brown DAB nuclear staining. HPF view is shown within the right lower corner. (C) HER2 has plasma membrane expression, HPF view staining is shown within the right lower corner that is noticed as plasma membrane brown staining sparing the nucleus. Pictures A, B and C collectively indicate luminal B molecular subtype. Photos D, E and F show no nuclear or plasma membrane staining of ER, PR and HER2 indicating Triple negative molecular subtype of breast cancer.figuring out their response to treatment would add a merit of drug predictive worth to this perform. Understanding the relation involving the gene polymorphism and expression and breast cancer characteristics (stage, grade and drug response) will pave the way, inside the future, for CYP1A1 dependent precision medicine regarding danger stratification, diagnosis, dru
