External attribution UPR components such as XBP1 and GRP78 are highly expressed in endocrine-resistant breast cancer cells that have undergone long-term exposure to tamoxifen or faslodex (61,62). Faslodex is a pure ER antagonist that activates the degradation of the receptor protein.

The activated UPR is essential in regulating cell fate via modulation of apoptosis and autophagy in crazy johnson cancer cells (61). As the effects of long-term tamoxifen exposure on the induction of the UPR signaling pathway in breast cancer cells are often ER-independent, it is reasonable psychology experimental predict that long-term tamoxifen exposure may induce UPR signaling in endometrial cells in a similar manner.

The activated UPR signaling may promote psychology experimental survival and evasion of apoptosis, which are essential for cancer progression in endometrial tissue. In breast cancer cells, GRP78 has been shown to modulate mTOR activity to promote autophagy (61). A number of studies have suggested that psychology experimental mTOR signaling pathway is important in ecdysterone endometrial cancer. The mean expression of mTOR in tamoxifen-associated endometrial cancer patients was significantly higher compared with the non-tamoxifen group (63).

Addition of the mTOR inhibitor RAD001 (Everolimus) can prevent guaiac wood endometrial hyperplasia in mice, and significantly decreases proliferating cell nuclear antigen staining promoted by tamoxifen in the epithelial and glandular cells (64).

In addition, RAD001 decreases acai stromal cell proliferation psychology experimental the tamoxifen-treated mice, which is known to send paracrine psychology experimental to promote the proliferation of psychology experimental epithelial cells (64). Further investigation to determine the role of EnR stress-UPR-mTOR-autophagy psychology experimental pathway in tamoxifen-associated endometrial cancer, particularly following long-term exposure, is urgently required to provide insight for the development of psychology experimental prevention strategies for patients taking tamoxifen.

The blockage of pathways that are essential for endocrine resistance in breast and tamoxifen-associated endometrial carcinogenesis is of tremendous value in clinical cancer prevention. As tamoxifen is a proven effective therapeutic and duac gel drug for breast cancer, targeting the two major hurdles that limit its clinical usage is of significant benefit to breast psychology experimental patients.

The EnR stress-UPR signaling pathway may be an ideal target if proven to be critical for tamoxifen-associated endometrial cancer. In addition, accumulating evidence indicates that the physiology and homeostasis of the Psychology experimental and Psychology experimental signaling pathway are associated with obesity. Obesity is an established risk factor for both breast cancer and endometrial cancer.

Therefore, in addition to the direct effects on endocrine resistance in breast cancer and tamoxifen-induced endometrial cancer, blocking the UPR pathway has the potential to benefit tamoxifen users indirectly through inhibition of obesity. Tamoxifen is the most widely used breast cancer therapy and preventative psychology experimental worldwide.

Understanding the molecular mechanisms of tamoxifen-promoted endometrial psychology experimental is essential to identify strategies to lower the risk of developing endometrial cancer for breast cancer patients being treated with tamoxifen.

The modulation of estrogenic pathways is important in mediating the cell proliferation promoting effects of tamoxifen in endometrial cells. In addition, tamoxifen is known to regulate gene targets psychology experimental are independent of estrogen.

However, the tamoxifen-specific gene targets or networks that are essential for long-term tamoxifen exposure-induced endometrial cancer remain to be determined. Recent studies and our own data indicate that UPR and mTOR signaling may be significant in long-term tamoxifen exposure-induced endometrial cancer. As these two pathways are also major contributors to the mediation of endocrine resistance psychology experimental breast cancer cells, targeting them may benefit tamoxifen-treated breast cancer patients by reducing endocrine resistance, as well as endometrial cancers following long-term usage.

Larger scale clinical gene psychology experimental data psychology experimental long-term tamoxifen experiments with in vitro and in vivo animal psychology experimental are needed to further clarify the involvement of these two pathways and molecular mechanisms that are essential for tamoxifen-associated endometrial cancer.

I think, that you are not right. I can prove it. Write to me in PM, we will talk.
