In this task, you are given an abstract of article. Your task is to generate title for this article. Preferred titles are under thirty words.

Example Input: Proteostasis is critical for maintaining cell function and proteome stability may play an important role in human embryonic stem cell (hESC) immortality. Notably, hESC populations exhibit a high assembly of active proteasomes, a key node of the proteostasis network. FOXO4, an insulin/IGF-1 responsive transcription factor, regulates proteasome activity in hESCs. We find that loss of FOXO4 reduces the potential of hESCs to differentiate into neural lineages. Therefore, FOXO4 crosses evolutionary boundaries and links hESC function to invertebrate longevity modulation.
Example Output: FOXO4 is necessary for neural differentiation of human embryonic stem cells.

Example Input: Although susceptibility of neurons in the brain to microbial infection is a major determinant of clinical outcome, little is known about the molecular factors governing this vulnerability. Here we show that two types of neurons from distinct brain regions showed differential permissivity to replication of several positive-stranded RNA viruses. Granule cell neurons of the cerebellum and cortical neurons from the cerebral cortex have unique innate immune programs that confer differential susceptibility to viral infection ex vivo and in vivo. By transducing cortical neurons with genes that were expressed more highly in granule cell neurons, we identified three interferon-stimulated genes (ISGs; Ifi27, Irg1 and Rsad2 (also known as Viperin)) that mediated the antiviral effects against different neurotropic viruses. Moreover, we found that the epigenetic state and microRNA (miRNA)-mediated regulation of ISGs correlates with enhanced antiviral response in granule cell neurons. Thus, neurons from evolutionarily distinct brain regions have unique innate immune signatures, which probably contribute to their relative permissiveness to infection.
Example Output: Differential innate immune response programs in neuronal subtypes determine susceptibility to infection in the brain by positive stranded RNA viruses

Example Input: Now that we have a good understanding of the DNA double strand break (DSB) repair mechanisms and DSB-induced damage signalling, attention is focusing on the changes to the chromatin environment needed for efficient DSB repair. Mutations in chromatin remodelling complexes have been identified in cancers, making it important to evaluate how they impact upon genomic stability. Our current understanding of the DSB repair pathways suggests that each one has distinct requirements for chromatin remodelling. Moreover, restricting the extent of chromatin modifications could be a significant factor regulating the decision of pathway usage. In this review, we evaluate the distinct DSB repair pathways for their potential need for chromatin remodelling and review the roles of ATP-driven chromatin remodellers in the pathways.
Example Output:
Roles of chromatin remodellers in DNA double strand break repair.
