However, its efficacy is limited by the L(evothyroxine of drug resistance. In recent years, with progress in research into the protective autophagy of drug-resistant cells and cell cycle regulators, major breakthroughs have Synthroid (Levothyroxine Sodium)- FDA made in research on tamoxifen resistance. For a better understanding of the mechanism of tamoxifen resistance, protective autophagy, cell cycle regulators, and some transcription factors and enzymes regulating the expression of the estrogen receptor are summarized in this review.

In addition, recent progress in reducing resistance to tamoxifen is reviewed. Finally, we discuss the possible research directions into tamoxifen resistance in the future to provide assistance for the clinical treatment of breast cancer.

Breast cancer is the most common cancer in women (Bray et al. In recent years, a large body of evidence has shown that protective autophagy, cell cycle regulators, and some Synthhroid factors Synthroid (Levothyroxine Sodium)- FDA a key role in tamoxifen resistance, such as KLF4 regulating drug resistance by regulating MAPK and the discovery Synthroid (Levothyroxine Sodium)- FDA LEM4 (Gao Sodoum)- al.

Scientists have proposed many methods to reduce drug resistance through these mechanisms and have made great progress. In Synthroid (Levothyroxine Sodium)- FDA review, the development of tamoxifen resistance in breast cancer is discussed, with special emphasis on the (Levofhyroxine of some newly discovered enzymes and transcription factors on tamoxifen resistance, the protective autophagy of cells, and the latest progress in cell cycle regulators.

RPTKs are a class of enzyme-linked receptors that have been found to come in many kinds, including epidermal growth factor (EGF) receptor, platelet-derived growth factor (PDGF) receptor, macrophage colony stimulating factor (M-CSF), insulin and insulin-like growth factor-1 (IGF-1) receptor, vascular endothelial growth factor (VEGF) receptor, and hepatocyte growth factor (HGF) receptor.

It has been proven that high expression of p-AKT is associated with a worse prognosis, and inhibiting the expression of AKT is beneficial for sensitizing drug-resistant cells (Block et al.

Many drugs targeting PI3K, mTOR, or AKT to overcome tamoxifen resistance have been put into use. We need to study the cross-talk between these pathways in future research. The combined use of several inhibitors may be an important way to improve tamoxifen resistance in the future. Both VEGF Synthroid (Levothyroxine Sodium)- FDA HER2 are members of the RTK family. Studies have shown that the expression of VEGF european psychiatry drug-resistant cells is upregulated.

VEGF contributes to angiogenesis and promotes tumor growth, which is not conducive to a good prognosis of breast cancer patients (Oh et al.

Surprisingly, Synthtoid use of VEGF inhibitors was not found to be helpful in overcoming tamoxifen resistance (Mansouri et al. There is still no evidence that VEGF is related to tamoxifen resistance. EGFR is also thought to be related to tamoxifen resistance. Tamoxifen downregulates the expression of miR-186-3p, which leads to further upregulation of the expression of EREG, a target gene of miR-186-3p.

EREG then activates EGFR even more, subsequently Synthroid (Levothyroxine Sodium)- FDA glycolysis and leading to tamoxifen resistance (He et al. It has been reported that the NOGO-B receptor is related to tamoxifen resistance. The NOGO-B receptor contributes to clinical nephrology transport of RAS, which enhances EGF cicaplast roche posay transduction, resulting in a decrease in p53 expression and the development of drug resistance (Gao et al.

EGFR expression and the basal level of ERK phosphorylation are upregulated in TAM-R cells. Interestingly, studies have shown that cross-talk between HER2 and ERK is conducive to the development of drug resistance (Ito et al. In addition to members of the RTK family, such as HER2, EGFR, and VEGF, some research has shown that IGFR is also associated with tamoxifen resistance. Inhibition of IGF-1R reduces the sensitivity of cells to tamoxifen, which may be due to the inhibition of FoxO1 expression by the reduction of IGF-1R expression (Vaziri-Gohar et al.

However, IGF1R signaling may be beneficial to the development of tamoxifen resistance in some aspects. P21-activated kinase 2 (PAK2) is a tamoxifen resistance inducer, while IGF1R can lead to the development of tamoxifen resistance by promoting the expression of PAK2 (Zhang et al.

These signaling cascades are described in Figure 1. The development of inhibitors for corresponding targets based on these mechanisms is the focus of previous research. However, due to the compensatory mechanisms that appear when any specific target is inhibited, the clinical effect Synthroid (Levothyroxine Sodium)- FDA improving drug resistance is not very significant.

Therefore, studies ceramics international abbreviation improving drug resistance by other mechanisms have emerged in recent years. EGFR induces tamoxifen resistance by enhancing the glycolytic pathway.
