Extracellular calcium reduction strongly increases the lytic capacity of pneumolysin from streptococcus pneumoniae in brain tissue [PDF]

, 2011
Background. Streptococcus pneumoniae causes serious diseases such as pneumonia and meningitis. Its major pathogenic factor is the cholesterol-dependent cytolysin pneumolysin, which produces lytic pores at high concentrations.

Expression of Calcium-Binding Proteins S100A2, S100A4 in Barrett's Adenocarcinomas

Neoplasia: An International Journal for Oncology Research, 2006
In this study, we investigated the mRNA, protein expression of S100A2, S100A4 in adenocarcinomas of the stomach, esophagus. Real-time reverse transcription-polymerase reaction analysis on 72 tumors revealed frequent overexpression of S100A2, S100A4 in ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Intestinal Calcium-Binding Protein and Rickets

Experimental Biology and Medicine, 1971
SummaryTo determine the influence of dietary phosphate deficiency and rickets on the level of intestinal calcium-binding protein, weanling rats were raised on 2 types of vitamin D-deficient diets. A group fed a rachitogenic diet, which was vitamin D-free, high in calcium, and low in phosphorus, developed rickets as measured by increased lactate ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
