Penitrem E
Penitrem E is an indole diterpenoid alkaloid with antitumor activity, isolated and extracted from Penicillium commune. Penitrem E is a BK channel antagonist. Penitrem E exerts its antagonistic effect by forming hydrogen bonds with the calcium-binding site of the BK channel, thereby upregulating the expression of TNF-α. Penitrem E can be used for research on breast cancer.

In Vitro
Penitrem E (compound 4) exhibits antiproliferative activity against MCF-7 (IC50 17.5 μM) and MDA-MB-231 (IC50 25.4 μM) human breast cancer cells[1].
Penitrem E (compound 4) inhibits migration of MDA-MB-231 cells with an IC50 of 20.3 μM[1].
Penitrem E (compound 4) is inactive in the Cultrex® BME cell invasion assay against MDA-MB-231 cells at 15.0 μM[1].
Penitrem E (48 h) exhibits antiproliferative activity against MDA-MB-231, BT-474, and SK-BR-3 breast cancer cell lines, as well as non-tumorigenic MCF-12A and CRL-2765 cells, with IC50 values ranging from 20.3 to 67.8 µM[2].
Penitrem E (24 h) does not alter KCNMA1 levels but increases TNF-α levels in BT-474 and SK-BR-3 breast cancer cells[2].

Protokoll
-
RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

Subcutaneous Cell-Line-Derived Xenograft
Subcutaneous cell-line-derived xenograft (CDX) models are established by implanting cultured human cancer cell lines into immunodeficient mice, where the injected cells form localized tumors that can be monitored in vivo as a measure of tumorigenic potential, growth kinetics, and treatment response. These models are widely used in oncology research because they allow reproducible tumor formation and enable comparative assessment of tumor growth between different cell lines or genetic manipulations in a controlled in vivo microenvironment. Subcutaneous implantation of cancer cells in immunodeficient mice is a standard approach for evaluating tumor growth behavior and therapeutic response across multiple cancer types, including prostate, esophageal, pancreatic, and colon cancer models.

Breast Cancer Modeling
Breast cancer is a heterogeneous cancer, and it has been distinguished into four subtypes: luminal A, luminal B, HER2-positive and basal-like. Molecular mutations, epigenetic alterations, hormone exposure and immune microenvironment are related to the progression of breast cancer.
