To define the molecular mechanisms that mediate hyperthermia-induced apoptosis, we performed microarray and computational gene expression analyses. U937 cells, a human myelomonocytic lymphoma cell line, were treated with hyperthermia at 42 degrees C for 90 min and cultured at 37 degrees C. Apoptotic cells ( approximately 15%) were seen 6 h after hyperthermic treatment, and elevated expression of heat shock proteins (HSPs) including Hsp27, Hsp40, and Hsp70 was detected, following the activation of heat shock factor-1. Of the 54,675 probe sets analyzed, 1334 were upregulated and 4214 were downregulated by >2.0-fold in the cells treated with hyperthermia. A non-hierarchical gene clustering algorithm, K-means clustering, demonstrated 10 gene clusters. The gene network U1 or U2 that was obtained from up-regulated genes in cluster I or IX contained HSPA1B, DNAJB1, HSPH1, and TXN or PML,
LYN
, and DUSP1, and were mainly associated with cellular compromise, and cellular function and maintenance or death, and cancer, respectively. In the decreased gene cluster II, the gene network D1 including CCNE1 and
CEBPE
was associated with the cell cycle and cellular growth and proliferation. These findings will provide a basis for understanding the detailed molecular mechanisms of apoptosis induced by hyperthermia at 42 degrees C in cells.

Through genome-wide association studies (GWAS), multiple inherited predispositions to acute lymphoblastic leukemia (ALL) have been identified in children. Most recently, a novel susceptibility locus at
ERG
was localized, exhibiting Hispanic-specific manner. In this study, we conducted a replication study to in all-age Chinese patients (
N
= 451), not only validating the novel
ERG
locus, but also systematically determining the impact of age on association status of the top GWAS signals. We found that single nucleotide polymorphisms at
ARID5B
,
IKZF1
,
CEBPE
,
PIP4K2A
were only significantly associated with ALL susceptibility in childhood patients with no
BCR-
ABL
fusion, while
GATA3
signal exhibited its significance in adults no matter carrying
BCR-
ABL
fusion or not. Moreover, the novel
ERG
SNP can be validated in pediatric patients without both
BCR-
ABL
and
ETV6-RUNX1
fusion. Our finding suggests the modifying effects of age on genetic predisposition to ALL, and highlights the impact of
ERG
SNP in Chinese patients.
