Multiple myeloma (MM) malignant plasma cells accumulate in the bone marrow (BM) where their interactions with the microenvironment promote disease progression and drug resistance. Previously, we have shown that bone marrow mesenchymal stem cells (BM-MSCs) (MM and normal donors- ND) derived extracellular matrix (ECM) affected MM cell lines differentially with a pro-MM effect attributed to MM-MSCs' ECM. Here we studied the composition of BM-MSC's ECM (ND versus MM) with focus on elastin (ELN).

Purpose: Pregnancy-associated breast cancer (PABC) is usually diagnosed at an advanced stage in comparison to non-pregnant women. The placenta secretes hormones and cytokines, which affect breast cancer progression. Previously, we demonstrated that human placental secretome facilitates the survival and migration of ERα+ breast cancer cells (BCCL), but pregnant women have a relatively high frequency of ERα-negative tumors.

The extracellular matrix (ECM) affects cancer cell characteristics. Inability of normal epithelial cells to attach to the ECM induces apoptosis (anoikis). Cancer cells are often anoikis resistant, a prerequisite for their metastatic spread.

During placental implantation, cytotrophoblast cells differentiate to extravillous trophoblast (EVT) cells that invade from the placenta into the maternal uterine blood vessels. The heat shock protein-27 (HSP27), the signal transducer and activator of transcription-3 (STAT3) and the eukaryotic translation initiation factor 4E (EIF4E) are involved in regulating EVT cell differentiation/migration. EIF4E and EIF4G compose the translation initiation complex, which is a major control point in protein translation.
