- Retinitis pigmentosa (RP) refers to a genetically heterogeneous group of progressive neurodegenerative diseases that result in dysfunction and/or death of rod and cone photoreceptors in the retina. So far, 18 genes have been identified for autosomal-dominant (ad) RP. Here, we describe an adRP locus (RP42) at chromosome 7p15 through linkage analysis in a six-generation Scandinavian family and identify a disease-causing mutation, c.449G -> A (p.S150N), in exon 6 of the KLHL7 gene. Mutation screening of KLHL7 in 502 retinopathy probands has revealed three different missense mutations in six independent families. KLHL7 is widely expressed, including expression in rod photoreceptors, and encodes a 75 kDa protein of the BTB-Kelch Subfamily within the BTB superfamily. BTB-Kelch proteins have been implicated in ubiquitination through Cullin E3 ligases. Notably, all three putative disease-causing KLHL7 mutations are within a conserved BACK domain; homology modeling suggests that mutant amino acid side chains can potentially fill the cleft between two helices, thereby affecting the ubiquitination complexes. Mutations in an identical region of another BTB-Kelch protein, gigaxonin, have previously been associated with giant axonal neuropathy. Our studies suggest an additional role of the ubiquitin-proteasome protein-degradation pathway in maintaining neuronal health and in disease.

- Background: The benefits and risks of long-term testosterone administration have been a topic of much scientific and regulatory interest in recent years. Aim: To assess long-term quality of life (QOL) and sexual function benefits of testosterone replacement therapy (TRT) prospectively in a diverse, multinational cohort of men with hypogonadism. Methods: A multinational patient registry was used to assess long-term changes associated with TRT in middle-age and older men with hypogonadism. Comprehensive evaluations were conducted at 6, 12, 24, and 36 months after enrollment into the registry. Outcomes: QOL and sexual function were evaluated by validated measures, including the Aging Males' Symptom (AMS) Scale and the International Index of Erectile Function (IIEF). Results: A total of 999 previously untreated men with hypogonadism were enrolled at 25 European centers, 750 of whom received TRT at at least one visit during the period of observation. Patients on TRT reported rapid and sustained improvements in QOL, with fewer sexual, psychological, and somatic symptoms. Modest improvements in QOL and sexual function, including erectile function, also were noted in RHYME patients not on TRT, although treated patients showed consistently greater benefit over time in all symptom domains compared with untreated patients. AMS total scores for patients on TRT were 32.8 (95% confidence interval = 31.3-34.4) compared with 36.6 (95% confidence interval = 34.8-38.5) for untreated patients (P < .001). Small but significant improvements in IIEF scores over time also were noted with TRT. Approximately 25% of treated and untreated men also used phosphodiesterase type 5 inhibitors, with notable differences in the frequency of phosphodiesterase type 5 inhibitor prescription use according to physician specialty and geographic site location. Clinical Implications: TRT-related benefits in QOL and sexual function are well maintained for up to 36 months after initiation of treatment. Strengths and Limitations: The major strengths are the large, diverse patient population being treated in multidisciplinary clinical settings. The major limitation is the frequency of switching from one formulation to another. Conclusion: Overall, we confirmed the broad and sustained benefits of TRT across major QOL dimensions, including sexual, somatic, and psychological health, which were sustained over 36 months in our treatment cohort.

Age-Dependent Transcriptome and Proteome Following Transection of Neonatal Spinal Cord of Monodelphis domestica (South American Grey Short-Tailed Opossum)

Tidskriftsartikel (refereegranskat)abstract
- This study describes a combined transcriptome and proteome analysis of Monodelphis domestica response to spinal cord injury at two different postnatal ages. Previously we showed that complete transection at postnatal day 7 (P7) is followed by profuse axon growth across the lesion with near-normal locomotion and swimming when adult. In contrast, at P28 there is no axon growth across the lesion, the animals exhibit weight-bearing locomotion, but cannot use hind limbs when swimming. Here we examined changes in gene and protein expression in the segment of spinal cord rostral to the lesion at 24 h after transection at P7 and at P28. Following injury at P7 only forty genes changed (all increased expression); most were immune/inflammatory genes. Following injury at P28 many more genes changed their expression and the magnitude of change for some genes was strikingly greater. Again many were associated with the immune/inflammation response. In functional groups known to be inhibitory to regeneration in adult cords the expression changes were generally muted, in some cases opposite to that required to account for neurite inhibition. For example myelin basic protein expression was reduced following injury at P28 both at the gene and protein levels. Only four genes from families with extracellular matrix functions thought to influence neurite outgrowth in adult injured cords showed substantial changes in expression following injury at P28: Olfactomedin 4 (Olfm4, 480 fold compared to controls), matrix metallopeptidase (Mmp1, 104 fold), papilin (Papln, 152 fold) and integrin alpha 4 (Itga4, 57 fold). These data provide a resource for investigation of a priori hypotheses in future studies of mechanisms of spinal cord regeneration in immature animals compared to lack of regeneration at more mature stages.
