An estrogen-dependent esterase activity in MCF-7 cells

open access: yesJournal of Steroid Biochemistry, 1987
The presence of steroidal esters in hormonally sensitive tissues lends importance to the esterases which convert the biologically inactive adducts to the parent potent forms. Accordingly, esterase-activities were studied in a human breast cancer model--the MCF-7 cell line. Tritiated estradiol esters- estradiol-17-acetate (EA), estradiol-17-valerate (EV)

A Naphthalimide‐Based NIR‐Emissive AIE Photosensitizer for Synergistic Apoptosis/Ferroptosis‐Mediated Antitumor Therapy and Broad‐Spectrum Bacterial Inactivation With Rapid Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
An ionic naphthalimide AIE photosensitizer (PS), TPAPV‐NIM‐M, anchors to cellular and bacterial membranes, emits in the far‐red/near‐infrared (NIR) region, and efficiently generates reactive oxygen species (ROS) under white light. Its membrane‐localized photodynamic action drives apoptosis/ferroptosis‐mediated tumor suppression and broad‐spectrum ...

HUMAN PREADIPOCYTES INHIBIT PROLIFERATION OF MCF-7 BREAST CANCER CELL LINE [PDF]

open access: yesActa Medica Iranica, 2006
Cancer cell-stromal cell interaction plays a crucial role in the growth and invasion of tumor cells of various organs. It has been recently suggested that adipocytes and preadipocytes, two specific types of stromal cells, affect the biological behavior ...

The Effect of Curcumin on Staphylococcus aureus Resistant to Aminoglycosides Isolated from Burn and Wound Infections

open access: yesMedical Journal of Babylon
Background: Thermal injury destroys the skin, the natural barrier to the external environment. As a result the burned area is prone to infection and colonization of microorganisms. The most common pathogenic colonizing bacteria are Staphylococcus aureus.

Triphenylphosphonium-modified mitochondria-targeted paclitaxel nanocrystals for overcoming multidrug resistance

open access: yesAsian Journal of Pharmaceutical Sciences, 2019
Mitochondria are currently known as novel targets for treating cancer, especially for tumors displaying multidrug resistance (MDR). This present study aimed to develop a mitochondria-targeted delivery system by using triphenylphosphonium cation (TPP ...

Turning Unpredictable Biomolecule Adsorption to Controlled Corona Formation: Focus on Carbon Nanomaterials

open access: yesAdvanced Materials, EarlyView.
Controlling the protein corona formation onto carbon nanomaterials (CNMs) enhances their functionalities as platforms for cancer theranostics. Here, we reviewed the effects of the intrinsic and acquired properties of CNMs on protein corona formation, the consequent biological and toxicological outcomes, and the strategies to reshape corona formation ...

Combination of 3D and 2D Small and Wide Angle X‐Ray Scattering Imaging Reveals Diminished Bone Quality in the Superior Human Femoral Neck Cortex

open access: yesAdvanced Materials, EarlyView.
Combined 2D and 3D X‐ray scattering imaging is used to analyse nanostructural properties in the inferior and superior cortex of 78 human femoral necks from 44 donors. The methodology allows for increased interpretation of nanostructure in a statistically relevant dataset, revealing nanostructural differences in anatomical locations critical to clinical

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

open access: yesAdvanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...
