    Insights

    This review explores endocrine resistance in hormone-dependent breast cancer. Understanding molecular mechanisms and pre-clinical strategies is crucial for overcoming treatment challenges in estrogen receptor-positive breast cancer.

    Area of Science:

    • Oncology
    • Endocrinology
    • Molecular Biology

    Background:

    • Breast cancer is the most common cancer in women, with 70% of cases being hormone-dependent.
    • Estrogen receptor alpha (ERα) presence is a key prognostic factor for endocrine therapy response.
    • Endocrine therapy resistance is a significant public health issue in breast cancer treatment.

    Purpose of the Study:

    • To review the molecular mechanisms driving resistance to endocrine therapies in breast cancer.
    • To present current pre-clinical strategies aimed at overcoming endocrine resistance.
    • To enhance understanding of treatment failure in hormone-dependent breast cancer.

    Main Methods:

    • Literature review of pre-clinical models and molecular mechanisms.
    • Analysis of studies investigating resistance pathways.
    • Synthesis of data on therapeutic strategies to overcome resistance.

    Main Results:

    • Detailed insights into molecular mechanisms of endocrine resistance are provided.
    • Various pre-clinical strategies to combat resistance are presented.
    • The review highlights the complexity of resistance development.

    Conclusions:

    • Understanding molecular mechanisms is essential for developing effective treatments.
    • Pre-clinical models offer valuable insights into overcoming endocrine resistance.
    • Further research into novel strategies is needed to improve patient outcomes in breast cancer.

    Treatment Resistant Cancers

    Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

    Adaptive Mechanisms in Cancer Cells

    Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
    Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

    Targeted Cancer Therapies02:57

    Targeted Cancer Therapies

    The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
    There are several types of targeted therapies against...

    Mitogens and the Cell Cycle

    Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

    Target Cell Response to Hormones01:22

    Target Cell Response to Hormones

    Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
    Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
