Maternal deprivation induces alterations in cognitive and cortical function in adulthood.

Early life trauma is a risk factor for a number of neuropsychiatric disorders, including schizophrenia (SZ). The current study assessed how an early life traumatic event, maternal deprivation (MD), alters cognition and brain function in rodents. Rats were maternally deprived in the early postnatal period and then recognition memory (RM) was tested in adulthood using the novel object recognition task.

The epigenetic regulator CXXC finger protein 1 is essential for murine hematopoiesis.

CXXC finger protein 1 (Cfp1), encoded by the Cxxc1 gene, binds to DNA sequences containing an unmethylated CpG dinucleotide and is an epigenetic regulator of both cytosine and histone methylation. Cxxc1-null mouse embryos fail to gastrulate, and Cxxc1-null embryonic stem cells are viable but cannot differentiate, suggesting that Cfp1 is required for chromatin remodeling associated with stem cell differentiation and embryogenesis. Mice homozygous for a conditional Cxxc1 deletion allele and carrying the inducible Mx1-Cre transgene were generated to assess Cfp1 function in adult animals.

Stability of avoidance behaviour following repeated intermittent treatment with clozapine, olanzapine or D,L-govadine.

Most antipsychotic drugs act as dopamine D2 receptor antagonists within the basal ganglia. These compounds have efficacy in the treatment of positive symptoms of schizophrenia but do not address the cognitive deficits that define this disorder. D,L-Govadine, a recently synthesized tetrahydroprotoberberine, shows efficacy on preclinical tests of antipsychotic action, as well as procognitive properties.

Overexpression of type VI collagen in neoplastic lung tissues.

Type VI collagen (COL6), an extracellular matrix protein, is important in maintaining the integrity of lung tissue. An increase in COL6 mRNA and protein deposition was found in the lungs of patients with pulmonary fibrosis, a chronic inflammatory condition with a strong association with lung cancer. In the present study, we demonstrated overexpression of COL6 in the lungs of non-small cell lung cancers.

Activation of dendritic cell function by soypeptide lunasin as a novel vaccine adjuvant.

The addition of an appropriate adjuvant that activates the innate immunity is essential to subsequent development of the adaptive immunity specific to the vaccine antigens. Thus, any innovation capable of improving the immune responses may lead to a more efficacious vaccine. We recently identified a novel immune modulator using a naturally occurring seed peptide called lunasin.

Acquired STAT4 deficiency as a consequence of cancer chemotherapy.

Signal Transducer and Activator of Transcription 4 (STAT4) is a transcription factor that is activated by IL-12 signaling and promotes Th1-cell differentiation and IFN-γ production. Defective IFN-γ production because of STAT4 mRNA and protein deficiency occurs after autologous stem cell transplantation for lymphoma. In the present study, we investigated the mechanisms of STAT4 deficiency in lymphoma patients.
