Objective: Psoriasis is associated with a high prevalence of metabolic syndrome (Ms), and patients with concomitant psoriasis and Ms are more severely affected and less responsive to treatment. however, the molecular mechanisms behind these effects are unknown. Recent studies have shown that leptin may serve as a molecular link between psoriasis and Ms, suggesting that high leptin concentrations may exacerbate psoriasis. however, the molecular mechanism of this effect is still unclear. We aimed to investigate the effect of leptin on autophagy in patients with psoriasis. Methods: From january 2021 to june 2022 in PlA General hospital, we enrolled 51 patients with psoriasis, including 21 patients with Ms and 30 without Ms, and 30 healthy controls who had undergone nevus surgery. We measured the epidermal leptin, P62, and lc3b concentrations of patients by immunohistochemistry, and measured the serum leptin concentration by enzyme-linked immunosorbent assay. We then performed correlation analyses to compare these proteins' concentrations between patients with concomitant psoriasis and Ms, patients with psoriasis alone, and healthy control groups. Additionally, we performed western blotting after in vitro culture of hacaT cells with different concentrations of leptin and measured the expression levels of the autophagy markers beclin1, lc3b, and P62; the differentiation markers K10, K16, and K17; and PI3K/AKT/mTOR signaling pathway-related proteins of hacat cells. Next, we transfected ATG5 into hacaT cells to revert autophagy and used the specific PI3K inhibitor lY294002 to block PI3K/AKT/mTOR signaling. The expression levels of K10, K16, and K17 of hacat cells were again measured. One-way analysis of variance was used for the comparison of means of multiple samples, and lsD-t post hoc test was used for comparison between the 2 groups. The counting data were analyzed by the chi-square test. correlations were evaluated by Pearson correlation analysis. Results: The serum l

Objective: xeroderma pigmentosum (xP) is a rare autosomal recessive dermatosis caused by genetic defects of DNA repair. This study was performed to detect and analyze the genes of 2 Uygur patients with xP and their families and assess the patients' phenotypes, which may enrich the understanding of the genetic skin disorder spectrum in xinjiang area. Methods: We collected the clinical data from 2 patients with xP and peripheral blood samples from the patients and their family members. The patients' DNA was sequenced and detected by sanger sequencing, and gene mutations were screened. Results: The proband in family 1 presented with brown maculae at the exposure site and squamous cell carcinoma secondary to a facial rash. The proband had a homozygous nucleotide variation of xPc c.2251-2A> G (A change from A to G in the penultimate position of the intron before the 2251 position in the coding region), which was a shear mutation. In this family, both parents were heterozygous, and no similar mutation detected in the sister. In family 2, the proband had scattered black brown spots and papules on the trunk and limbs. and his younger sister was also a patient. The proband and his younger sister had homonucleotide variation of xPA c.631c> T, which was nonsense mutation, resulting in the codon for Arg No.211 being changed into termination codon (***211x), thus terminating the peptide chain synthesis prematurely. All the normal individuals in the two families were heterozygotes, and homozygous mutations occurred in all the patients, which was consistent with the autosomal recessive inheritance. conclusion: xP is rare in Uygur population. This study expanded the mutation spectrum of xP and provided a basis for early diagnosis, treatment, prognostic prediction, and prenatal genetic consultation. © 2022 hospital for skin Diseases (Institute of Dermatology), chinese Academy of Medical sciences, and chinese Medical Association, published by Wolters Kluwer, Inc.
