Retinoid X receptor-α (RXRα) is a kind of nuclear receptor and is a target of cancer prevention and treatment in various types of cancers. Cancer stem cells (CSCs) are regarded as the main cause of carcinoma metastasis, tumor recurrence and chemotherapy resistance. So far, the mechanism how RXRα regulates CSCs remains unknown. In the present study, we found that RXRα was up-regulated in head and neck squamous cell carcinoma (HNSCC) tissues and the enriched HNSCC cancer stem cells. Over-expression of RXRα was able to expand the CSC-like properties in HNSCC cells, while knockdown of RXRα could repress the stemness respectively...

Photodynamic therapy (PDT) has been indicated for oral squamous cell carcinoma (OSCC) at early stages. Chemo and radio-resistance are frequently observed in OSCC, but it is unknown whether this tumor can develop resistance to PDT. It was investigated the process of acquiring resistance to multiple cycles of PDT by using OSCC cells. We also analyzed the expression of anti-apoptotic proteins and those related to Akt/mTOR pathway. Sub-lethal doses of PDT were applied, consisting of a constant concentration of 5-aminolevulinic acid (5-ALA) (1 mM, 4-hour incubation) and increasing irradiation dose with LED (from 5...

Overexpression of LIM and SH3 protein 1 (LASP1) is required for colorectal cancer (CRC) development and progression. Here, C-Jun activation domain-binding protein-1 (Jab1), also known as COPS5, was verified as a new LASP1-interacting protein through yeast two-hybrid assay. The role of COPS5 in LASP1-mediated CRC progression remains unknown. GST pull-down assay indicated that the SH3 domain of LASP1 could directly bind to MPN domain of COPS5. In vitro gain- and loss-of-function analyses revealed the stimulatory role of COPS5 on CRC cell proliferation, migration and invasion...

The cytosolic iron-sulfur (Fe-S) cluster assembly (CIA) pathway functions to incorporate inorganic Fe-S cofactors into a variety of proteins, including several DNA repair enzymes. However, the mechanisms regulating the CIA pathway are unknown. We describe here that the MAGE-F1-NSE1 E3 ubiquitin ligase regulates the CIA pathway through ubiquitination and degradation of the CIA-targeting protein MMS19. Overexpression or knockout of MAGE-F1 altered Fe-S incorporation into MMS19-dependent DNA repair enzymes, DNA repair capacity, sensitivity to DNA-damaging agents, and iron homeostasis...

The MHC class I pathway, presenting endogenously derived peptides to T lymphocytes, is hijacked in many pathological conditions. This affects MHC class I levels and peptide presentation at the cell surface leading to immune escape of cancer cells or microbes. It is therefore important to identify the molecular mechanisms behind MHC class I expression, processing and antigen presentation. The identification of NLRC5 as regulator of MHC class I transcription was a huge step forward in understanding the transcriptional mechanism involved...

INTRODUCTION: Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal dominant disease. It is caused by constitutional mutations in the FLCN gene. Since BHDS is a rare syndrome therefore it is unknown to many physicians. However, it is important to identify this rare syndrome at early stages because incidence of renal cancer in BHD patients is very high and its detection at early stages can prevent its metastasis. Hence, we want to present a case of BHDS and draw the attention of the treating physician to this rare inherited disorder and discuss its appropriate diagnosis and management...

Light localization is a phenomenon which arises due to the interference effects of light waves inside a disordered optical medium. Quantification of degree light localization in optical media is widely used for characterizing degree of structural disorder in that media. Recently, this light localization approach was extended to analyze structural changes in biological cell like heterogeneous optical media, with potential application in cancer diagnostics. Confocal fluorescence microscopy was used to construct 'optical lattices', which represents 2D refractive index map corresponding to the spatial mass density distribution of a selected molecule inside the cell...
