Trapping prostate cancer cells to keep them from spreading provides hope

Trapping prostate cancer stem cells with self-assembling nanomaterials inhibits colony formation and cell division in vitro. The approach may offer a new treatment strategy for metastatic hormone-refractory prostate cancer by targeting cancer stem cells, which are thought to be the origin of tumor metastasis.

Estrogen reduces aggression in breast cancer

Researchers found that oestrogen can reduce the proportion of breast cancer stem cells, explaining a better prognosis for tumours expressing the oestrogen receptor. This study presents new insights into oestrogen's effect on cancer stem cells and opens doors to developing tools for preventing breast cancer.

Researchers identified a strategy to target human breast cancer stem cells by blocking the protein CXCR1. The approach selectively depleted cancer stem cells in mice xenotransplanted with human breast cancer cells, leading to reduced tumor growth and metastasis. This finding provides hope for women with breast cancer.

Depleting breast cancer-initiating cells by targeting the protein CXCR1

A recent study identifies CXCR1 as a crucial protein in targeting human breast cancer stem cells. Inhibiting this protein selectively depletes the cancer stem cell population, leading to reduced tumor growth and metastasis. The findings suggest that strategies targeting CXCR1 may offer a promising approach for treating breast cancer.

Potential new 'twist' in breast cancer detection

Researchers at Johns Hopkins Medicine have discovered a protein called Twist that accurately distinguishes stem cells driving aggressive breast cancer from other cancer cells. The protein's presence alone can flag a tumor cell as a breast cancer stem cell, suggesting new potential for early detection and treatment strategies.

Echoes of phlogiston in stem cell biology

Stem cell biology faces challenges in defining molecular characteristics, with potency and self-renewal not exclusive to stem cells. A new perspective suggests considering 'stemness' as a system property, rather than individual cell traits, which may lead to improved understanding of cancer stem cells.

Penn State College of Medicine research isolates liver cancer stem cells prior to tumor formation

Researchers at Penn State College of Medicine have identified a population of cancer stem cells in the liver prior to tumor formation. These malignant stem cells have been found to be resistant to chemotherapy and are thought to play a key role in driving liver cancer formation. The study suggests that targeting these cells could poten...

Cancer stem cells generated by cancer outgrowth

Researchers discovered that growing mouse skin cells in spheres can lead to generation of cells with properties of cancer stem cells. The study found that mutation of the retinoblastoma tumor suppressor gene family led to reprogramming of differentiated cells into cancer stem cells.

First genome-wide expression analysis yields better understanding of how leukemia develops

A genome-wide expression analysis identified 3,005 differentially expressed genes, including a ribosome and T-cell receptor signaling pathway. The study provides critical insight into the differences between leukemic stem cells and normal blood stem cells, potentially leading to targeted therapies.
