Background: Approximately 8% of the human genome is composed of retroviral sequences, which are known as human endogenous retroviruses (HERVs) and, have been implicated in both health status and disease. Recently, indirect evidence for a possible role of retroviral elements in the systemic response to stress signals has been provided by several studies. In the present study, we sought to evaluate the relationship between HERVs and major burn in humans.
Method: We investigated the prevalence of HERV families by reverse transcriptase PCR (RT-PCR) in cell-free plasma samples from patients with burns and from normal individuals.
Results: Different prevalences of HERV families were observed in the plasma samples from the burn patient group and normal group. Compared with the prevalences of HERV-W and HERV-K in the normal group, in the burn patient group, the prevalence of HERV-W was significantly lower (P<0.001), but the prevalence of HERV-K was higher (P=0.059).
Conclusions: Our study of the prevalences of HERVs revealed that the activation of certain HERV families may be influenced not only by burns but also by the initial treatments that were used to address these injuries.

Clinical Manifestations and Challenges in Adolescent and Adult Females With Classic Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency.

Classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH) is a rare genetic condition that results in cortisol deficiency and excess production of adrenal androgens. While the introduction of newborn screening for CAH has reduced morbidity and mortality, management of CAH remains challenging. Lifelong treatment with glucocorticoids is required to replace the endogenous cortisol deficiency and reduce excess adrenal androgens.

Triple-negative breast cancer (TNBC) is a difficulty and bottleneck in the clinical treatment of breast cancer due to a lack of effective therapeutic targets. Herein, we first report that secernin 2 (SCRN2), an uncharacterized gene in human cancer, acts as a novel tumor suppressor in TNBC to inhibit cancer progression and enhance therapeutic sensitivity to poly(ADP-ribose) polymerase (PARP) inhibition both in vitro and in vivo. SCRN2 is downregulated in TNBC through chaperone-mediated autophagic degradation, and its downregulation is associated with poor patient prognosis.

Given the high lethality of cancer, identifying its risk factors is crucial in both epidemiology and cancer research. This study employs a novel bibliometric analysis method, which uses the tidytext package and tidy tools in R. This approach surpasses traditional tools like VOSviewer, offering more comprehensive and complex keyword data and clearer results compared to Bibliometrix.

Natural killer (NK) cells can control metastasis through cytotoxicity and IFN-γ production independently of T cells in experimental metastasis mouse models. The inverse correlation between NK activity and metastasis incidence supports a critical role for NK cells in human metastatic surveillance. However, autologous NK cell therapy has shown limited benefit in treating patients with metastatic solid tumors.

Background: Osteoarthritis (OA) is one of the most common bone disorders and has a serious impact on the quality of life of patients. LncRNA-HCP5 (HCP5) is downregulated in OA tissues. However, the latent function and regulatory mechanisms of HCP5 in OA are unclear.
