Background: Fidgetin-like 1 (FIGNL1) is extensively overexpressed in a variety of cancers. It facilitates non‑small cell lung cancer tumor cell proliferation and hepatocellular carcinoma formation due to abnormal DNA repair. Clinically relevant data indicates that its high expression is linked with the poor prognosis of patients with renal clear-cell carcinoma, low-grade gliomas, and hepatocellular carcinoma. Nevertheless, the scope of FIGNL1’s involvement in cancer, particularly colorectal cancer (CRC), remains unclear.

Aims: To investigate the function of FIGNL1 in CRC.

Study design: Cell culture study.

Methods: The TCGA database and immunohistochemistry analysis were employed to investigate FIGNL1 expression in CRC tissue. A cell viability assay was performed using the Cell Counting Kit-8. The cell migration and invasion were evaluated using the transwell assay. Small interfering RNA (siRNA) transfection was conducted to knockdown FIGNL1 expression. Infection with FIGNL1 overexpression lentivirus was performed to promote FIGNL1 overexpression. The STRING database was employed for predicting protein interaction.

Results: FIGNL1 was substantially upregulated in human CRC tissues and was associated with TNM stages and lymph node metastasis in patients. The inhibition of CRC cell proliferation, migration, and invasion in Caco-2 cells was achieved by silencing FIGNL1 using siRNA. Additional investigations suggested that FIGNL1 overexpression could promote CRC cell proliferation, migration, and invasion via P38 signaling pathway activation in Colo-205 cells. Subsequent experiments demonstrated that FIGNL1-mediated P38 phosphorylation was contingent upon SPIDR interaction.

Conclusion: These results implied that FIGNL1 was a potential anticancer drug target, which also offered a novel strategy for future CRC treatment.

Takotsubo syndrome (TTS) still remains as an enigmatic phenomenon. In particular, long-term challenges (including clinical recurrence and persistent symptoms) and specific entities in the setting of TTS have been the evolving areas of interest. On the other hand, a significant gap still exists regarding the proper risk-stratification of this phenomenon in the short and long terms. The present paper, the second part (part-2) of the consensus report, aims to discuss less well-known aspects of TTS including specific entities, challenges after recovery and risk-stratification.

Background: Depression and anxiety, the most prevalent neuropsychiatric manifestations in Parkinson’s disease (PD), negatively impact their quality of life.

Aims: To determine whether the chronic nasal administration of kisspeptin-54 (KP-54) could. Alleviate symptoms of anxiety and depression in hemi-Parkinsonian rats.

Study design: Experimental study.

Methods: This study included adult Sprague Dawley male rats who were administered either a vehicle (artificial cerebrospinal fluid) or 6-hydroxydopamine (6-OHDA) unilaterally into the medial forebrain bundle. The vehicle, or KP-54 (3 nmol/kg, applied topically to the rhinarium), was administered daily for a seven-day period. The sucrose preference test (SPT), elevated plus maze test (EPMT), and open field test (OFT) were implemented to evaluate depression- and anxiety-like behaviors, respectively, seven days following the lesion surgery. Gamma-aminobutyric acid (GABA) concentrations in the amygdala were quantified using mass spectrometry. Tyrosine hydroxylase in substantia nigra was analyzed using immunohistochemistry.

Results: The nasal delivery of KP-54 significantly reduced depressionand anxiety-like behaviors that were induced by 6-OHDA, as indicated by the results of the SPT, OFT, and EPMT. Moreover, it was observed that nasal KP-54 effectively mitigated 6-OHDA-induced motor deficits and the loss of nigral dopaminergic neurons. The nasal administration of KP-54 augmented the decline in GABA levels in the amygdala induced by 6-OHDA. Furthermore, effective correlations were established between GABA concentrations and behavioral parameters.

Conclusion: The nasal delivery of KP-54 could function as a viable therapeutic alternative for treating mood-related disorders in PD.
