Issue of hiring a criminal

Hiring a criminal. Criminal refers to a person who has committed to the crime. In some other words, there is a crime that called as felony. Felony is a crime that classified as the most serious type of offenses such as fraud, physical harm or large scale of theft. Thus, hiring a criminal is defined as company wanted to hire a person who has criminal records background as an employee. Nowadays, criminal history is quite common in the country like USA, which has over 6.6 million people been under correctional supervision such as jail, prison and parole. According to Kurlychek, Bushway, & Denver (2019), employers were asked questions regarding to the criminal history and use various methods and sources to collect the criminal background information. In contrast, some companies would prefer to hire people who are nominated and found that prison record of felony convictions reduced the employer’s motivation to hire an employee (Griffith & Young, 2017). Thus, employers are making decision based on the criminal history and checks for the record to make the hiring decisions (Young & Ryan, 2019) even though the connection between the criminal records and the employment is still at the infancy stage (Griffith, Rade, & Anazodo, 2019). In recent years, the policy attention is focus on the employment for the people who has criminal background (Agan & Starr, 2017). Consequently, “Ban the Box” policies has created to revise when and how the criminal histories were disclosed to move forward to the fair chance of employment selection process (Griffith & Young, 2017) to prevent the inequalities of economics and racial problems (Agan & Starr, 2017)

Inhibitor of caspase-activated DNase expression enhances caspase-activated DNase expression and inhibits oxidative stress-induced chromosome breaks at the mixed lineage leukaemia gene in nasopharyngeal carcinoma cells

BACKGROUND: Nasopharyngeal carcinoma (NPC) is commonly found in Asia, especially among the Chinese ethnic group. Chromosome rearrangements are common among NPC patients. Although the mechanism underlying the chromosome rearrangements in NPC is unclear, various mechanisms including activation of caspase-activated DNase (CAD) were proposed to contribute to chromosome rearrangements in leukaemia. Activation of CAD can be initiated by multiple agents, including oxidative stress, which is well implicated in carcinogenesis. CAD is the main enzyme that causes DNA fragmentation during apoptosis, and CAD is also implicated in promoting cell differentiation. In view of the role of oxidative stress in carcinogenesis and CAD activation, and since CAD was suggested to contribute to chromosome rearrangement in leukaemia, we hypothesise that oxidative stress-induced CAD activation could be one of the mechanisms that leads to chromosome rearrangements in NPC. METHODS: SUNEI cells were treated with various concentrations of H(2)O(2) for different period of time to ensure that cells undergo H(2)O(2)-induced MLL gene cleavage. Transfections with hCAD, mCAD, mutant hCAD, or cotransfection with hCAD and mICAD, and cotransfection with mutant hCAD and mICAD were performed. Gene expression was confirmed by Western blotting and MLL gene cleavage was assessed by inverse polymerase chain reaction (IPCR). RESULTS: Treatment with H(2)O(2) clearly induces cleavages within the MLL gene which locates at 11q23, a common deletion site in NPC. In order to investigate the role of CAD, CAD was overexpressed in SUNE1 cells, but that did not result in significant changes in H(2)O(2)-induced MLL gene cleavage. This could be because CAD requires ICAD for proper folding. Indeed, by overexpressing ICAD alone or co-expressing ICAD with CAD, Western blotting showed that CAD was expressed. In addition, ICAD overexpression also suppressed H(2)O(2)-induced MLL gene cleavage, suggesting a possible role of CAD in initiating chromosome cleavage during oxidative stress. CONCLUSIONS: Oxidative stress mediated by H(2)O(2) induces cleavage of the MLL gene, most likely via the caspase-activated DNase, CAD, and CAD expression requires ICAD. Since the MLL gene is located at 11q23, a common deletion site in NPC, thus stress-induced CAD activation may represent one of the mechanisms leading to chromosome rearrangement in NPC
