Electric Fields Regulate In Vitro Surface Phosphatidylserine Exposure of Cancer Cells via a Calcium-Dependent Pathway.

Cancer is the second leading cause of death worldwide after heart disease. The current treatment options to fight cancer are limited, and there is a critical need for better treatment strategies. During the last several decades, several electric field (EF)-based approaches for anti-cancer therapies have been introduced, such as electroporation and tumor-treating fields; still, they are far from optimal due to their invasive nature, limited efficacy and significant side effects.

Phosphatidylserine: The Unique Dual-Role Biomarker for Cancer Imaging and Therapy.

Cancer is among the leading causes of death worldwide. In recent years, many cancer-associated biomarkers have been identified that are used for cancer diagnosis, prognosis, screening, and early detection, as well as for predicting and monitoring carcinogenesis and therapeutic effectiveness. Phosphatidylserine (PS) is a negatively charged phospholipid which is predominantly located in the inner leaflet of the cell membrane.

SapC-DOPS as a Novel Therapeutic and Diagnostic Agent for Glioblastoma Therapy and Detection: Alternative to Old Drugs and Agents.

Glioblastoma multiforme (GBM), the most common type of brain cancer, is extremely aggressive and has a dreadful prognosis. GBM comprises 60% of adult brain tumors and the 5 year survival rate of GBM patients is only 4.3%.

Targeting of elevated cell surface phosphatidylserine with saposin C-dioleoylphosphatidylserine nanodrug as individual or combination therapy for pancreatic cancer.

Pancreatic cancer is one of the deadliest of cancers with a five-year survival of roughly 8%. Current therapies are: surgery, radiation and chemotherapy. Surgery is curative only if the cancer is caught very early, which is rare, and the latter two modalities are only marginally effective and have significant side effects.

A rapid bioanalytical tool for detection of sequence-specific circular DNA and mitochondrial DNA point mutations.

Mutations in mitochondrial DNA (mtDNA) have been an essential cause of numerous diseases, making their identification critically important. The majority of mtDNA screening techniques require polymerase chain reaction (PCR) amplification, enzymatic digestion, and denaturation procedures, which are laborious and costly. Herein, we developed a sensitive PCR-free electrokinetic-based sensor combined with a customized bis-peptide nucleic acid (bis-PNA) and gamma-PNA (γ-PNA) probes immobilized on beads, for the detection of mtDNA point mutations and sequence-specific supercoiled plasmid DNA at the picomolar range.
