SOX2 commands LIM homeobox transcription factors in choroid plexus development and tumorigenesis.

Background: Choroid plexus (CP) tumors are rare brain neoplasms that mainly affect the pediatric population. Unlike benign CP papilloma (CPP), CP carcinoma (CPC) is an aggressive cancer with a dismal survival rate. Despite chromosome-wide rearrangements, drivers of most CP tumors remain elusive except recurrent alterations in TP53.

Macrophage-derived extracellular vesicles as new players in chronic non-communicable diseases.

Macrophages are innate immune cells present in all tissues and play an important role in almost all aspects of the biology of living organisms. Extracellular vesicles (EVs) are released by cells and transport their contents (micro RNAs, mRNA, proteins, and long noncoding RNAs) to nearby or distant cells for cell-to-cell communication. Numerous studies have shown that macrophage-derived extracellular vesicles (M-EVs) and their contents play an important role in a variety of diseases and show great potential as biomarkers, therapeutics, and drug delivery vehicles for diseases.

PIPKI Regulates CCL2 Expression in Colorectal Cancer by Activating AKT-STAT3 Signaling.

Colorectal cancer (CRC) remains the third most commonly diagnosed cancer, ranking second among the most common causes of cancer-related mortality. Immune checkpoint therapy has recently been shown to have great potential. However, only some patients respond to immune checkpoint blockade, indicating the unmet need for determining the underlying mechanism of colorectal cancer immunosuppression.

Protocadherin-8 promotes invasion and metastasis via laminin subunit γ2 in gastric cancer.

Growing evidence suggests that protocadherins (PCDH) play crucial roles in pathogenesis and progression of cancers, including gastric cancer (GC). Protocadherin-8 (PCDH8) was previously reported to be involved in metastasis of GC, but functional studies yielded inconsistent results and the molecular mechanism remained unknown. The present study aimed to explore the clinical relevance, function and molecular mechanism of PCDH8 in GC.

CXCR2 promotes breast cancer metastasis and chemoresistance via suppression of AKT1 and activation of COX2.

Metastasis and chemoresistance are two major causes of breast cancer death. We show here that the chemokine receptor CXCR2 was overexpressed in breast cancer cell lines and tissues. CXCR2 promoted anti-apoptosis, anti-senescence, and epithelial-to-mesenchymal transition (EMT) of breast cancer cells, leading to the enhanced metastasis and chemoresistance.

COX-2 promotes breast cancer cell radioresistance via p38/MAPK-mediated cellular anti-apoptosis and invasiveness.

Radioresistance is one of the major barriers to improve the survival rate of breast cancer patients. Cyclooxygenase 2 (COX-2) is usually overexpressed in highly invasive and metastatic breast cancer, which may indicate an association with breast cancer radioresistance. The function role of COX-2 was investigated by using a radioresistant breast cancer cell line MDA-MB-231/RR10 and its parental cell line MDA-MB-231 cells before or after COX-2 was silenced by a specific small hairpin RNA (shRNA).

Expression of CXCL14 and its anticancer role in breast cancer.

CXCL14, also known as breast and kidney-expressed chemokine, was initially identified as a chemokine highly expressed in the kidney and breast. The exact function of CXCL14 in human breast cancer is still unclear, although it has been testified to play an anti-tumor role in other tumors, including head and neck squamous cell carcinoma, lung cancer, prostate cancer, and so on. In this study, we tried to demonstrate the relationship between CXCL14 and breast cancer.
