Cleavage and Blastulation01:33

Cleavage and Blastulation

After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.
Pinching-off of Coated Vesicles01:32

Pinching-off of Coated Vesicles

Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...
Cell Motility through Blebbing01:16

Cell Motility through Blebbing

Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Types of Membrane Protrusions01:28

Types of Membrane Protrusions

The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These membrane protrusions are a result of cytoskeletal rearrangement. The most  widely observed cell protrusions include lamellipodia, pseudopodia, filopodia, microvilli, invadopodia, and podosomes. These protrusions can be of two types — static or dynamic.
The microvilli, an example of stable protrusions, are finger-like projections with a...
Structure of Cadherins01:25

Structure of Cadherins

The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins”   is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This diversity of cadherins...
Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

    Summary
    This summary is machine-generated.

    Androgens like testosterone propionate can treat metastatic breast cancer in postmenopausal women. However, the synthetic androgen calusterone offers no significant advantages over older treatments.

    Area of Science:

    • Oncology
    • Endocrinology

    Background:

    • Androgens are established therapeutic agents for postmenopausal women with metastatic breast cancer.
    • Early studies demonstrated objective regression rates exceeding 20% with testosterone propionate.
    • Subsequent synthetic androgens have not improved upon testosterone propionate's efficacy or toxicity profile.

    Purpose of the Study:

    • To evaluate the efficacy and toxicity of calusterone (7 beta,17 alpha-dimethyltestosterone) as a potential therapeutic agent for metastatic breast cancer.
    • To compare calusterone's therapeutic profile against existing androgen therapies, including testosterone propionate.

    Main Methods:

    • Review of early and subsequent clinical trial data for calusterone.
    • Comparative analysis of efficacy (objective regression rates) and toxicity data for calusterone versus other androgens.
    • Assessment of the consistency and reliability of available clinical data on calusterone.

    Main Results:

    • Early clinical trials suggested calusterone possessed superior efficacy and reduced toxicity compared to testosterone propionate.
    • Later studies failed to consistently confirm these initial promising findings.
    • Data on calusterone's performance in breast cancer treatment remain largely inconsistent.

    Conclusions:

    • Current evidence indicates that calusterone does not offer significant therapeutic advantages over other androgens for treating breast cancer.
    • The initial perception of calusterone as an "ideal androgen" was not substantiated by subsequent research.
    • Further investigation may be needed to clarify calusterone's role, if any, in breast cancer therapy.
