(Submitter supplied) Progressive ventricular enlargement is one of the most reproducible and recognizable structural abnormalities in schizophrenia, and is associated with more severe symptoms and poorer clinical outcome. The mechanisms of ventricular enlargement in schizophrenia is unknown. We identified that progressive ventricular enlargement is associated with deceleration of motile cilia beating in ependymal cells lining ventricular walls in murine models of schizophrenia-associated 22q11 deletion syndrome (22q11DS). more...

(Submitter supplied) Among the fundamental unresolved questions in psychiatry is why symptoms of psychosis, such as auditory hallucinations in schizophrenia, fail to appear until early adulthood. Here we report that in mouse models of 22q11.2 deletion syndrome (22q11DS), a leading genetic cause of schizophrenia, synaptic transmission at thalamocortical inputs to the auditory cortex becomes disrupted later in life, thereby recapitulating the adult onset of psychosis. more...

(Submitter supplied) This represents an unbiased evaluation of the transcriptional response in the prefrontal cortex and hippocampus areas in the Df(16)A/+ mice, a mouse model of human 22q11 microdeletion syndrome. These mice were generated by chromosomal engineering and carry a microdeltion of ~1.3Mb in the mouse locus syntenic to the human 22q11.1 The reasoning behind this expression profiling is that alterations in transcriptional programs reflect either downstream (immediate or remote) effects of the deficiency or reactive (compensatory) changes, and can thus point to affected biological processes and molecular functions. more...

Analysis of hippocampi of Df(16)A/+ animals. Df(16)A/+ animals carry microdeletions of about 1.3Mb in the locus syntenic to human 22q11.2. Individuals with 22q11.2 microdeletions show behavioral and cognitive deficits and are at high risk of developing schizophrenia.

(Submitter supplied) Autism spectrum disorders (ASD) frequently accompany macrocephaly, which could involve hydrocephalic enlargement of brain ventricles. Katnal2 is a microtubule-related protein strongly implicated in ASD. However, it remains unclear whether Katnal2 knockout (KO) in mice leads to microtubule-related cellular deficits and ASD-related phenotypes. We found here that Katnal2-KO mice display social communication deficits, including excessive courtship ultrasonic vocalizations and decreased mating success. more...

(Submitter supplied) We are using induced pluripotent stem cell (iPSC) technology to study neuropsychiatric disorders associated with 22q11.2 microdeletions (del), the most common known schizophrenia (SZ) -associated genetic factor. Several genes in the deleted region have been implicated; one of the more promising candidates is DGCR8, which codes for a protein involved in microRNA (miRNA) biogenesis. We carried out miRNA expression profiling (miRNA-seq) on neurons generated from iPSCs derived from controls and SZ patients with 22q11.2 del.

(Submitter supplied) Df16(A)+/- mice line is a model of human 22q11 microdeletion syndrome. We conducted an unbiased evaluation of the transcriptional difference in the prefrontal cortex and hippocampus areas between mutant and wild type animals at two early developmental stages (embryonic day 17 and postnatal day 6). These mice were generated by chromosomal engineering and carry a microdeltion of ~1.3Mb in the mouse locus syntenic to the human 22q11.1 The reasoning behind this expression profiling is that consistent alterations in transcriptional programs reflect either downstream (immediate or remote) effects of the deficiency or reactive (compensatory) changes, and can thus point to affected biological processes and molecular functions. more...

(Submitter supplied) Although being essential to respiratory and reproductive tracts multiciliogenesis, TAp73 is dispensable for multiciliogenesis in the ventricles. TAp73 KO is accompanied by dramatic changes in ciliogenic microRNAs miR34bc and miR449 family members, suggestin TAp73 functions partially thorugh posttranscriptional nodes in brain ciliogenesis.

(Submitter supplied) Cancer of the larynx is the second most common upper-aerodigestive cancer, and laryngeal squamous cell carcinoma (LSCC) is the major histological form. However, the molecular mechanism within LSCC progression remains poorly understood. MicroRNA-based target therapy is a promising approach in cancer therapy and offers multiple advantages as compared with the conventional treatment modalities. Hence, there is a need to identify the key microRNA involved in the progression of LSCC. more...

(Submitter supplied) Primary cilium serves as a cellular “antenna” to sense environmental signals. Ciliogenesis requires the removal of CP110 to convert the mother centriole into the basal body. Actin dynamics is also critical for cilia formation. How these distinct processes are properly regulated remains unknown. Here we show that miR-129-3p, a microRNA conserved in the vertebrates, controlled cilia assembly by down-regulating both CP110 and four proteins critical for actin dynamics, Arp2, Toca1, abLIM1, and abLIM3. more...
