Boron analysis and imaging of cells with 2-hr BPA exposure by using micro-proton particle-induced gamma-ray emission (PIGE). Appl Radiat Isot 2020; 165:109334. [PMID: 32739796 DOI: 10.1016/j.apradiso.2020.109334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2019] [Revised: 07/05/2020] [Accepted: 07/08/2020] [Indexed: 10/23/2022]
Abstract
Particle-induced gamma-ray emission (PIGE), which measures prompt gamma rays at 428 keV from 10B (p, p'γ) 7Be, was used to confirm the boron distribution within 2hr-BPA-exposed cells. Distribution images of potassium, phosphate, and boron and the whole spectrum showed the ratios of boron counts to total (%) as follows: control group: 1.35 ± 0.073%; 2hr boron exposure group: 2.33 ± 0.35%; and boron exposure/wash group: 1.58 ± 0.095%. Micro-beam PIXE/PIGE can be a promising tool for visualization of intracellular Boron.

Abstract
An external scanning ion microbeam system has been developed for in-air micro-PIXE analysis at JAERI Takasaki. The analysis system is widely used for various researches in recent years. The system consists of the external scanning ion microbeam system, a multi-parameter data acquisition system, a file transfer protocol (FTP) server and analysis software. The software of the system provides a graphical user interface for interaction between users and an experimental setup. The server is connected to the Internet and allows remote users to access the experimental data.

Changes of heavy metal, metallothionein and heat shock proteins in Sertoli cells induced by cadmium exposure. Toxicol In Vitro 2008; 22:1469-75. [PMID: 18556172 DOI: 10.1016/j.tiv.2008.04.021] [Citation(s) in RCA: 39] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2007] [Revised: 04/02/2008] [Accepted: 04/30/2008] [Indexed: 11/29/2022]
Abstract
In this study, we examined the levels of Cadmium (Cd), iron (Fe) and zinc (Zn), which were considered to be involved in Sertoli cell damage caused by Cd exposure. We also examined metallothionein (MT), heat shock protein 70 (Hsp70) and heme oxygenase-1 (HO-1) expressions in Sertoli cells induced by Cd exposure. Evaluation by the in-air micro-particle induced X-ray emission (PIXE) method revealed that Cd and Fe distribution was increased in the cytoplasm of Sertoli cells after Cd exposure. By contrast, Zn was decreased in the cytoplasm of Sertoli cells after Cd exposure. It was suggested that the target of Cd toxicity was the cytoplasm of Sertoli cells, Fe was considered to enhance damage to Sertoli cells caused by Cd exposure. The DNA fragmentation rate was determined by ELISA after Cd exposure to Sertoli cells. It remained essentially unchanged with 2.5 microM Cd exposure of Sertoli cells; however, MT, Hsp70 and HO-1 were significantly increased by Cd exposure. As a result, Cd-induced MT was protected Sertoli cells against apoptosis, and Cd-induced HO-1 was involved in protection against oxidative stress. Incidentally, MT, Hsp70 and HO-1 showed similar responses to Cd exposure.

The changes of heavy metal and metallothionein distribution in testis induced by cadmium exposure. Biometals 2007; 21:71-81.

Abstract
Cadmium (Cd) is known to cause various disorders in the testis, and metallothionein (MT) is known as a protein, which has a detoxification function for heavy metals. However, the changes of Fe, Cu, and Zn distribution in the testis induced by Cd exposure have not been well examined. Moreover, only a few studies have been reported on the localization of MT after Cd exposure. In this study, we have investigated the changes of Fe, Cu, and Zn distribution in Cd-exposed testis by a newly developed in air micro-Particle Induced X-ray Emission (PIXE) method. Also, we examined the distribution of MT expression in testis. In the testis of Cd-treated rats with significant increases of lipid peroxidation, the sertoli cell tight junction was damaged by Cd exposure, resulting from disintegration of the blood testis barrier (BTB). Evaluation by in air micro-PIXE method revealed that Cd and Fe distribution were increased in the interstitial tissues and seminiferous tubules. The histological findings indicated that the testicular tissue damage was advanced, which may have been caused by Fe flowing into seminiferous tubules followed by disintegration of the BTB. As a result, Fe was considered to enhance the tissue damage caused by Cd exposure. MT was detected in spermatogonia, spermatocytes, and Sertoli's cells in the testis of Cd-treated rats, but was not detected in interstitial tissues. These results suggested that MT was induced by Cd in spermatogonia, spermatocytes, and Sertoli's cells, and was involved in the resistance to tissue damage induced by Cd.
