Objectives: ATPase family AAA domain-containing 2 plays an important role in tumor progression including cell cycle, proliferation, apoptosis and chemoresistance. However, the expression of ATPase family AAA domain-containing 2 in colorectal cancer and its significance are still unclear. The aim of this study was to examine the expression of ATPase family AAA domain-containing 2 in colorectal cancer.
Methods: Immunohistochemistry was used to determine the expression of ATPase family AAA domain-containing 2 in 155 colorectal cancer and 30 matched adjacent noncancerous tissues. The correlation of ATPase family AAA domain-containing 2 expression with clinicopathological variables was assessed using chi-square test. Patient survival was analyzed using the Kaplan-Meier and log-rank tests. Cox regression was performed for the multivariate analysis of prognostic factors.
Results: High expression of ATPase family AAA domain-containing 2 was detected in 58.1% of the colorectal cancers and was significantly associated with advanced tumor-node-metastasis stage (P = 0.044), poor differentiation (P = 0.028), deep infiltration (P < 0.001), lymphovascular invasion (P = 0.006), lymph node metastasis (P = 0.024) and recurrence (P = 0.022). Patients with high ATPase family AAA domain-containing 2 expression had significantly poorer overall survival and disease-free survival (both P < 0.001) when compared with patients with low expression of ATPase family AAA domain-containing 2. The multivariate analysis showed that ATPase family AAA domain-containing 2 was an independent factor for both overall survival (P = 0.003; hazard ratio (HR): 2.356; 95% confidence interval (CI): 1.335-4.158) and disease-free survival (P = 0.001; HR: 2.643; 95% CI: 1.489-4.693).
Conclusions: These results showed that ATPase family AAA domain-containing 2 overexpression was associated with progression and prognosis of colorectal cancer.

CD8T cells within the tumor microenvironment (TME) are often functionally impaired, which limits their ability to mount effective anti-tumor responses. However, the molecular mechanisms behind this dysfunction remain incompletely understood. Here, we identified valosin-containing protein (VCP) as a key regulator of CD8T cells suppression in hepatocellular carcinoma (HCC).

Background And Hypothesis: ATP6V1B1 encodes a subunit of the vacuolar H+-ATPase and pathogenic variants are associated with autosomal recessive distal renal tubular acidosis (dRTA) with deafness. Heterozygous variants predicted to affect a specific amino acid, Arg394, have been recurrently reported in dRTA but their significance has been unclear. We hypothesised that these variants are associated with a dominant disease mechanism.

The human ATP-binding cassette (ABC) transporter ABCA7 participates in the lipidation of apolipoprotein ApoE, a commonly recognized risk factor for Alzheimer's disease (AD). How ABCA7 is involved in the molecular pathogenesis of AD remains poorly understood. Using cryoelectron microscopy (cryo-EM), we determined ABCA7 structures in the apo and substrate-bound forms, respectively.
