Dear Editor,Breast cancer is a leading type of cancer in women,the treatment of basal type,including triple negative breast cancer(TNBC),remains challenging due to its aggressive behaviors and lack of targeted therapeutic options1.F-box proteins(FBPs)can serve as either oncogenes or tumor suppressors depending on their substrates,and various studies have been conducted on their involvement in different types of cancer and play significant roles in cancer development and ***,the related mechanisms and targets of F-box protein 15(FBX015)are still remain unclear in human breast cancers.

AIM: To examine the effect of intravitreal adenoviral vector-mediated tristetraprolin(Ad-TTP) on VEGF m RNA expression in a rat model of laser-induced choroidal ***: Ad-TTP was prepared using a commercial kit. Retinal laser-induced photocoagulation(10 spots per eye) was performed on rats in this experimental choroidal neovascularization(CNV) model. Rats were divided into four groups: control(single intravitreal injection of balanced salt solution, n =10), laser-induced CNV(photocoagulation only, n =20), laser-induced CNV plus Ad-TTP injection(photocoagulation plus a single intravitreal Ad-TTP injection, n =20) and Ad-TTP injection only(n =10). Changes in choroidal morphology were evaluated in ten rats in the laser only and the laser plus Ad-TTP groups. Two weeks after laser injury, the size of CNV was calculated by perfusion with high-molecular-weight fluorescein isothiocyanate(FITC)-dextran. VEGF m RNA expression in retina-choroid tissue from ten rats in each group was measured by reverse transcription polymerase chain reaction(RT-PCR). RESULTS: Two weeks after treatment, the area of laser-induced CNV was reduced by approximately 60% in the rats given the Ad-TTP injection compared with that in the laser-only group. There was a tendency toward decreased VEGF m RNA expression in the Ad-TTP injection ***: A single intravitreal injection of Ad-TTP significantly suppressed CNV size in this experimental laser-induced CNV model. Ad-TTP injection also decreased VEGF m RNA expression compared with that inthe laser-induced CNV group. The present study is meaningful as the first study to investigate the effect of tristetraprolin delivered via intravitreal injection.

Chronic ethanol consumption is well established as a major risk factor for type-2 diabetes(T2D), which is evidenced by impaired glucose metabolism and insulin resistance. However, the relationships between alcoholconsumption and the development of T2 D remain controversial. In particular, the direct effects of ethanol consumption on proliferation of pancreatic β-cell and the exact mechanisms associated with ethanolmediated β-cell dysfunction and apoptosis remain elusive. Although alcoholism and alcohol consumption are prevalent and represent crucial public health problems worldwide, many people believe that low-tomoderate ethanol consumption may protect against T2 D and cardiovascular diseases. However, the J- or U-shaped curves obtained from cross-sectional and large prospective studies have not fully explained the relationship between alcohol consumption and T2 D. This review provides evidence for the harmful effects of chronic ethanol consumption on the progressive development of T2 D, particularly with respect to pancreatic β-cell mass and function in association with insulin synthesis and secretion. This review also discusses a conceptual framework for how ethanolproduced peroxynitrite contributes to pancreatic β-cell dysfunction and metabolic syndrome.

Ionizing radiation is one of the most effective tools in cancer therapy. In a previous study, we reported that protein tyrosine kinase (PTK) inhibitors modulate the radiation responses in the human chronic myelogenous leukemia (CML) cell line K562. The receptor tyrosine kinase inhibitor, genistein, delayed radiation-induced cell death, while non-recepter tyrosine kinase inhibitor, herbimycin A (HMA) enhances radiation-induced apoptosis. In this study, we focused on the modulation of radiation-induced cell death by genistein and performed PCR-select suppression subtractive hybridization (SSH) to understand its molecular mechanism. We identified human thymidine kinase 1 (TK1), which is cell cycle regulatory gene and confirmed expression of TK1 mRNA by Northern blot analysis. Expression of TKl mRNA and TK1 enzymatic activity were parallel in their increase and decrease. TK1 is involved in G1-S phase transition of cell cycle progression. In cell cycle analysis, we showed that radiation induced G2 arrest in K

This study is to investigate the characteristic features of Acanthamoeba keratitis（AK） that differentiating it from herpetic epithelial keratitis（HEK） using anterior segment optical coherence tomography（AS-OCT）. Medical records of three eyes of each AK and herpetic keratitis who had AS-OCT examination were reviewed in this study. Slitlamp biomicroscopy and AS-OCT was performed on the initial visit and on every follow-up visits in all patients. In all three AK cases, reflective bands in the corneal stroma that correspond to the area of radial keratoneuritis were observed. The depth of the reflective bands varied in each case. After AK treatment, slit-lamp biomicroscopy confirmed that radial keratoneuritis had resolved and AS-OCT confirmed that reflective bands in the corneal stroma had also disappeared in all patients. Unlike the AS-OCT results found in AK, highly reflective HEK lesions were observed only in the subepithelial area, not in the stroma. AS-OCT seems to be helpful analyzing the specific depth of the lesion which enables to distinguish AK from HEK.
