The Role of the Brain in the Pathogenesis and Physiology of Polycystic Ovary Syndrome (PCOS). [PDF]

, 2019
Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder, affecting at least 10% of women of reproductive age. PCOS is typically characterized by the presence of at least two of the three cardinal features of hyperandrogenemia (high ...

Deficiency of Leucine‐Rich Repeat Containing G Protein‐Coupled Receptor 4 in Pancreas Reduces β Cell Mass

Advanced Science, EarlyView.
In islet β cells, LGR4 binds with Rspondin to activate the Wnt‐β‐catenin‐Ccnd1 axis, leading to a subsequent increase in cell proliferation. On the other hand, LGR4 also binds with RANKL, thus suppressing the phosphorylation of p44/p42 MAPK and p65 NF‐κB and subsequent cell apoptosis.

Panic-like defensive behavior but not fear-induced antinociception is differently organized by dorsomedial and posterior hypothalamic nuclei of Rattus norvegicus (Rodentia, Muridae)

Brazilian Journal of Medical and Biological Research, 2012
The hypothalamus is a forebrain structure critically involved in the organization of defensive responses to aversive stimuli. Gamma-aminobutyric acid (GABA)ergic dysfunction in dorsomedial and posterior hypothalamic nuclei is implicated in the origin of ...

MicroRNAs are involved in the hypothalamic leptin sensitivity

Epigenetics, 2018
The central nervous system monitors modifications in metabolic parameters or hormone levels (leptin) and elicits adaptive responses such as food intake and glucose homeostasis regulation. Particularly, within the hypothalamus, pro-opiomelanocortin (POMC)

How the brain represents the reward value of fat in the mouth. [PDF]

, 2009
The palatability and pleasantness of the sensory properties of foods drive food selection and intake and may contribute to overeating and obesity. Oral fat texture can make food palatable and pleasant.

SpaBatch: Deep Learning‐Based Cross‐Slice Integration and 3D Spatial Domain Identification in Spatial Transcriptomics

Advanced Science, EarlyView.
SpaBatch is an end‐to‐end multi‐slice spatial transcriptomics data integration framework. It simultaneously performs embedding learning, spatial feature denoising and reconstruction, batch effect correction, and spatial domain optimization, effectively correcting batch effects and achieving accurate 3D spatial domain identification.

Secretin-dependent signals in the ventromedial hypothalamus regulate energy metabolism and bone homeostasis in mice

Nature Communications
Secretin, though originally discovered as a gut-derived hormone, is recently found to be abundantly expressed in the ventromedial hypothalamus, from which the central neural system controls satiety, energy metabolism, and bone homeostasis.

Synaptic Dysfunction in the Anterior Cingulate Cortex Underlies Pain‐Anxiety Comorbidity in a Mandibular Asymmetry Mouse Model

Advanced Science, EarlyView.
This study establishes a mandibular asymmetry (MA) mouse model that recapitulates chronic orofacial pain and anxiety comorbidity. Anterior cingulate cortex (ACC) hyperactivation and synaptic dysfunction are identified as central neural mechanisms underlying these pathologies, with chemogenetic inhibition of ACC CaMKII+ neurons effectively reversing ...
