PARylation of HMGA1 desensitizes esophageal squamous cell carcinoma to olaparib.

As a chromatin remodelling factor, high mobility group A1 (HMGA1) plays various roles in both physiological and pathological conditions. However, its role in DNA damage response and DNA damage-based chemotherapy remains largely unexplored. In this study, we report the poly ADP-ribosylation (PARylation) of HMGA1 during DNA damage, leading to desensitization of esophageal squamous cell carcinoma (ESCC) cells to the poly(ADP-ribose) polymerase 1 (PARP1) inhibitor, olaparib.

HMGA1 sensitizes esophageal squamous cell carcinoma to mTOR inhibitors through the ETS1-FKBP12 axis.

Esophageal carcinoma is amongst the prevalent malignancies worldwide, characterized by unclear molecular classifications and varying clinical outcomes. The PI3K/AKT/mTOR signaling, one of the frequently perturbed dysregulated pathways in human malignancies, has instigated the development of various inhibitory agents targeting this pathway, but many ESCC patients exhibit intrinsic or adaptive resistance to these inhibitors. Here, we aim to explore the reasons for the insensitivity of ESCC patients to mTOR inhibitors.

However, the role of in the alleviation of radiation enteritis remains unknown.

Myofascial acupuncture versus routine acupuncture for mechanical neck pain: a protocol for a multicentre randomised controlled trial.

Introduction: Mechanical neck pain (MNP) is defined as pain in the area of the neck and/or neck-shoulder provoked by body mechanics and which adversely affects physical, psychological and social function. The treatments for MNP are limited. Previous studies and clinical experience have indicated that myofascial acupuncture might be a better treatment option for MNP, but the efficacy is controversial.

Effect of electroacupuncture on cyclic adenosine monophosphate-protein kinase A-vanillic acid receptor subtype 1 of the transient receptor potential/PLK-protein kinase C-vanillic acid receptor subtype 1 of the transient receptor potential pathway based on RNA-seq analysis in prostate tissue in rats with chronic prostatitis/chronic pelvic pain syndrome.

Objective: To investigate the analgesic mechanism of electroacupuncture (EA) in rats with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

Methods: Thirty male SD rats were randomly divided into sham group, model group and EA group, with ten rats in each group. The CP/CPPS model was prepared by injecting 50 μL of complete Freund's adjuvant (CFA) into the ventral lobes of the prostate tissue, and the sham group was injected with the same dose of saline.

Objective: To explore the possible mechanism of electroacupuncture (EA) underlying improvement of chronic pelvic pain syndrome (CPPS).

Methods: Fifty SD rats were randomly divided into control, model, sham operation, EA and sham EA groups (=10 rats in each group). The CPPS model was established by injecting complete Freund's adjuvant (CFA, 50 μL) into the ventral lobes of the prostate.

[Application of teaching method for the interpretation of acupoint names in the course of ].

The paper summarizes the valuable experience of the famous teachers of all generations in the teaching & research room of meridians and acupoints of Beijing University of CM. The shortcomings are presented when the acupoints are explained in accordance with the flowing route of meridians in classroom teaching of Hence, it is proposed that the acupoint names should be interpreted specially for the acupoints distributed on the same meridians or adjacent ones. It is suggested to emphasize the correlation of each acupoint with its adjacent ones from the perspective of the cultural connotation of acupoint names, and then, the differences and similarities in their clinical indications can be analyzed.
