    4. Study showed that SV2C is highly expressed in the basal ganglia and hippocampus of mice and that there is a specific and progressive decrease in SV2C mRNA and protein expression in both Huntington's disease (HD) mice and a cell model. These findings suggest that the synaptic dysfunction in HD results from the mutant Htt-mediated inhibition of SV2C transcriptional expression. PMID: 29713895
    5. Inverse relationship has been found between the length of CAG HTT repeats and age at clinical onset of Huntington's Disease in Indian population. PMID: 29619771
    6. Polyglutamine expansion appears to induce a 'change of function', possibly a 'gain of function', in the huntingtin protein, which leads to various molecular and cellular cascades of pathogenesis, including oxidative stress, mitochondrial dysfunction, glutamatergic dysfunction and neuroinflammation. [Review] PMID: 28674979
    7. The number of repeats in HTT, had a non-linear effect on a measure of general intelligence with an inverted U shape pattern. Increasing repeat length was associated with higher GAI scores up until roughly 40-41 repeats. After this peak, increasing repeat length was associated with declining GAI scores. PMID: 29685790
    8. Results show that not only prolonged fasting but also scheduled feeding without forcibly reducing calorie intake alters nutrient-sensing pathways and activates autophagy in mouse brain. This intervention furthermore reduces the amounts of mutant HTT protein, and may thus contribute to its clearance. PMID: 29510748
    9. The single overexpression of DNAJB1 in HEK293T cells is sufficient to profoundly reduce HttExon1Q97 aggregation and represents a target of future therapeutic avenues for HD. PMID: 29212816
    10. We found that the HTTexon1 mRNA is present in fibroblasts from juvenile HD patients and can also be readily detected in the sensory motor cortex, hippocampus and cerebellum of post-mortem brains from HD individuals, particularly in those with early onset disease. PMID: 28465506
    11. The two kinases HIPK3 and MAPK11 effect on Huntingtin (HTT)levels are mutant HTT protein (mHTT)-dependent, providing a feedback mechanism in which mHTT enhances its own level thus contributing to mHTT accumulation and disease progression. PMID: 29151587
    12. Lipid-based micellar nanoparticles promote aggregation of huntingtin exon-1 peptides. This study characterizes the interaction of two such peptides, htt(NT)Q7 and htt(NT)Q10 comprising the N-terminal amphiphilic domain of huntingtin followed by 7 and 10 glutamine repeats, respectively, with 8 nm lipid micelles. Monomer-dimer equilibrium exists on the surface of the micelles. PMID: 29727175
    13. Study shows that lifetime depression risk was higher with both relatively short and relatively large Huntigtin CAG repeat sizes in the normal range. PMID: 29225330
    14. huntingtin T3 phosphorylation is greatly reduced in samples from Huntington's disease models and in Huntington's disease patients, and T3 phosphorylation alters Huntingtin exon 1 protein conformation and aggregation properties PMID: 29162692
    15. Multiple factors that decreased cytotoxicity of Htt-103Q (changing the length of or sequences adjacent to the polyQ, altering ploidy or chaperone dosage, or deleting anti-aging factors) altered the Htt-103Q aggregation pattern in which the suite of mid-sized aggregates at 6 hr were most correlative with cytotoxicity. PMID: 27721444
    16. Monomeric Huntingtin Exon 1 Has Similar Overall Structural Features for Wild-Type and Pathological Polyglutamine Lengths PMID: 28937758
    17. This study aims to establish the current state of the IT-15 (HTT) gene in different Ecuadorian ethnic groups and patients by determining CAG triplet repeats, compared with the ethnicity of individuals. PMID: 28369732
    18. cryo-electron microscopy to determine the structure of full-length human HTT in a complex with HTT-associated protein 40 (HAP40; encoded by three F8A genes in humans) to an overall resolution of 4 A PMID: 29466333

    20. CAG repeat length in the mutant allele was found to be a relatively consistent and significant risk factor for the progression of Huntington disease. PMID: 28111121
    21. Study of gene expression profiles of human Huntington disease (HD) brains and HTT transgenic model rats. Results show for the first time that TFIID complex formation is reduced, while soluble TBP is increased in an HD model. This finding suggests that mutant HTT is a competitor instead of a recruiter of polyQ-containing transcription factors in the transcription process in HD. PMID: 28153533
    22. Studies show that distinct protein homeostasis (proteostasis) nodes such as chaperone-mediated folding and proteolytic systems regulate the aggregation and degradation of HTT. The ability to maintain proteostasis of HTT declines during the aging process. Conversely, mechanisms that preserve proteostasis delay the onset of Huntington's disease. [review] PMID: 28753941
    23. Studies indicate huntingtin (htt) as contributing factor to the development of Huntington's disease. PMID: 28971465
    24. To address the function of normal HTT protein we generated HTT(+/-) and HTT(-/-) lines. The same phenotype emerged in HTT(-/-) but not HTT(+/-) lines. Conclude that Huntington disease (HD) is a developmental disorder characterized by chromosomal instability that impairs neurogenesis, and that HD represents a genetic dominant-negative loss of function, contrary to the prevalent gain-of-toxic-function hypothesis. PMID: 29378824
    25. APP heterozygosity results in greater decreases of cortical APP in Transgenic (Tg) versus non-Tg mice. Mutant huntingtin transgenic mice develop brain iron accumulation as a result of greater suppression of APP levels. Elevated brain iron in Tg mice was associated with a decline in motor endurance consistent with a disease promoting effect of iron in the YAC128 model of human Huntington's Disease. PMID: 28550267
    26. A pathogenic HTT form (polyQ-HTT) probably disrupts the protein-protein interactions in hippocampus and distorts the dynamics of molecular processes in the synapses. PMID: 28900094
    27. Study examined the cellular and behavioural consequences of local overexpression of mutant huntingtin (mHTT) in the hippocampus of adult mice; and showed that local expression of mHTT in the dentate gyrus has deleterious effects, including its neurogenic capacity, with functional behavioural consequences, which fits well with recent data on hippocampal deficits seen in patients with Huntington's disease. PMID: 28286179
    28. study provides an extensive resource for CAG length-dependent changes in microRNA expression in disease-vulnerable and -resistant brain regions in HD mice, and provides new insights for further investigation of microRNAs in HD pathogenesis and therapeutics PMID: 29324753
    29. findings indicate that htt(NT) molecules do not have a strong orientational preference for parallel or antiparallel orientation of the helices within the aggregate. However, a parallel packed bundle of helices would support the idea of increased polyglutamine concentration, to pave the way for cross-beta structures. PMID: 28539049
    30. Between July 1999 and January 2004, 1001 clinically unaffected adults at risk for HD who had chosen not to undergo predictive genetic testing for the presence or absence of the mutated HTT gene were enrolled in this non-interventional, observational, longitudinal study PMID: 27740685

    32. Mutant huntingtin protein was preferentially expressed within the anterior horn of the gray matter, in both cervical and lumbar sections of spinal cord from Huntington's disease patients. PMID: 29171910
    33. early-state transcriptional changes and aggregate formation in a Huntington's disease cell model PMID: 28499347
    34. cells expressing mutant huntingtin have a dysregulated transcriptional response to epidermal growth factor stimulation PMID: 27988204
    35. This study demonstrated that the number of repeats in HTT, below disease threshold, confers advantageous changes in brain structure and general intelligence (IQ): the higher the number of repeats, the greater the change in brain structure, and the higher the higher IQ. PMID: 27870408
    36. This study explores the aggregation and toxicity of human huntingtin in yeast. PMID: 27220690
    37. Mutation in HTT causes Huntington's disease (HD); aggregates of mutated HTT cause apoptosis in neurons of HD patients. Data suggest that both MLF1 and MLF2 preferentially interact with mutated N-terminal HTT; MLF1/MLF2 reduce number of neurons (Neuro2A cell line) containing mutant HTT aggregates and subsequent apoptosis. (HTT = Huntingtin protein; MLF = myeloid leukemia factor) PMID: 27840155
    38. Study investigated the fundamental intracellular aggregation process of eight different-length N-terminal fragments of Htt in both short (25Q) and long polyQ (97Q). PolyQ-expansion was only required for fragments of less than 171 amino acids to aggregate. Longer fragments aggregated predominately through a non-polyQ mechanism, involving at least one, and probably more distinct clustering mechanisms. PMID: 28339398
    39. Study shows that mutant huntingtin protein (mHTT) has an expanded polyglutamine stretch that may adopt multiple conformations and has a slower degradation rate due to its resistance to selective autophagy in human cells and brains, revealing mechanisms of its higher toxicity. PMID: 28869595
    40. We provide evidence that nuclear accumulation of Httex1-103Q enhances its cytotoxicity, suggesting that the RQC machinery plays an important role in protecting cells against the adverse effects of polyQ expansion proteins. PMID: 28864412
    41. results suggest that subject-to-subject variation contributes more to variability in N-terminal huntingtin fragments than post mortem delay PMID: 28570578
    42. We report that endogenous huntingtin protein directly participates in oxidative DNA damage repair. Using novel chromobodies to detect endogenous human huntingtin in live cells, we show that localization of huntingtin to DNA damage sites is dependent on the kinase activity of ataxia telangiectasia mutated (ATM) protein. PMID: 28017939
    43. the long HTT 3'UTR suppresses translation. PMID: 28494017
    44. Soluble oligomers of PolyQ-expanded huntingtin target a multiplicity of key cellular factors. PMID: 27570076
    45. Peripheral huntingtin silencing does not ameliorate central signs of disease in the B6.HttQ111/+ mouse model of Huntington's disease PMID: 28453524
    46. The present data emphasize the relevance of expanded CAG RNA to Huntington's disease pathogenesis, indicate that inhibition of HTT expression is not required to reverse motor deficits, and further suggest a therapeutic potential for LNA-CTG in polyglutamine disorders. PMID: 27721240
    47. Although the mutant huntingtin gene is expressed widely, neurons of the striatum and cortex are selectively affected in Huntington's disease (HD). Our results suggest that this selectivity is attributable to the reduced expression of Foxp1, a protein expressed selectively in striatal and cortical neurons that plays a neuroprotective role in these cells. PMID: 28550168
    48. Huntingtin 513 fragment has unique physical interactions with the cellular environment, including, but not limited to, the protein degradation machinery. PMID: 28282438
    49. The CAG repeat expansion in the exon 1 of the protein huntingtin (HTTex1) that causes the disease leads to the formation of HTT fibrils in vitro and vivo. The fibrils of mutant HTTex1 are able to seed the aggregation of wild type HTTex1 into amyloid fibrils, which in turn can seed the fibril formation of mutant HTTex1. PMID: 28621522
    50. Long CAG length could be associated with lower breast cancer incidence, but could also be paradoxically associated with cancer severity. PMID: 26980106
