AbstractLactate dehydrogenase A (LDHA) is highly expressed in various tumors. However, the role of LDHA in the pathogenesis of B‐cell lymphoma remains unclear. Analysis of data from The Cancer Genome Atlas (TCGA) and Genotype‐Tissue Expression (GTEx) databases revealed an elevated LDHA expression in diffuse large B‐cell lymphoma (DLBC) tissues compared with normal tissues. Similarly, our results demonstrated a significant increase in LDHA expression in tumor tissues from the patients with B‐cell lymphoma compared with those with lymphadenitis. To further elucidate potential roles of LDHA in B‐cell lymphoma pathogenesis, we silenced LDHA in the Raji cells (a B‐cell lymphoma cell line) using shRNA techniques. Silencing LDHA led to reduced mitochondrial membrane integrity, adenosine triphosphate (ATP) production, glycolytic activity, cell viability and invasion. Notably, LDHA knockdown substantially suppressed in vivo growth of Raji cells and extended survival in mice bearing lymphoma (Raji cells). Moreover, proteomic analysis identified feline sarcoma‐related protein (FER) as a differential protein positively associated with LDHA expression. Treatment with E260, a FER inhibitor, significantly reduced the metabolism, proliferation and invasion of Raji cells. In summary, our findings highlight that LDHA plays multiple roles in B‐cell lymphoma pathogenesis via FER pathways, establishing LDHA/FER may as a potential therapeutic target.

Naturally occurring UV active compounds, commonly present in almost all source waters, can be rapidly monitored by their ultraviolet absorbance at 260 nm (E260). Herein, the extent of correlation between the E260 and the removal efficiency of the hazardous contaminants, endocrine disrupters and dioxins, were investigated using various treatment and river source waters. The detection of various types of hazardous contaminants using sophisticated analytical methods, such as high resolution gas chromatography (HRGC)/high resolution mass spectrometry (HRMS) and high performance liquid chromatography (HPLC)/inductively coupled plasma (ICP)/mass spectrometry (MS), as well as various short-term bioassays, can require hours or even days for results to be obtained. The removal of the E260 correlated well with those of individual contaminants, such as endocrine disruptor chemicals and dioxins, with the various treatment processes employed. In the plots of the endocrine disrupters against the DOC/E260, a correlation was found with the endocrine activity of the Korean/Japanese river waters employed in this study.

Detection of various types of contaminants in water treatment plant by sophisticated analytical methods such as inductively coupled plasma/mass spectrometry and gas chromatography/mass spectrometry requires hours to days to provide the results. Because naturally occurring ultraviolet (UV) active compounds are commonly present in almost all source waters and can be rapidly monitored by UV absorbance at 260 nm (E260), the extent of correlation between the removal efficiency of E260 and the removal efficiency of As(V) with minimum soluble residual Al by coagulation process was investigated. Percentage removals for E260 were well correlated to those of As(V). When sufficient alum or polyaluminum chloride (PACl) was added for 60-65% removal of E260, 90-95% removal of As(V) was achieved with minimum soluble residual Al regardless of the initial level of turbidity, E260, and As(V). As E260 analysis is precisely available even by an unskilled plant operator in a few minutes, E260 removal efficiency appears to be the promising economical indicator for monitoring the effectiveness of the coagulation process for the removal of contaminants with minimum residual Al.
