Nuclear lamin A/C phosphorylation by loss of androgen receptor leads to cancer-associated fibroblast activation.

Alterations in nuclear structure and function are hallmarks of cancer cells. Little is known about these changes in Cancer-Associated Fibroblasts (CAFs), crucial components of the tumor microenvironment. Loss of the androgen receptor (AR) in human dermal fibroblasts (HDFs), which triggers early steps of CAF activation, leads to nuclear membrane changes and micronuclei formation, independent of cellular senescence.

A cub and sushi domain-containing protein with esterase-like activity confers insecticide resistance in the Indian malaria vector Anopheles stephensi.

Chemical insecticides (organophosphates and pyrethroids) in the form of IRS (Indoor Residual Sprays) and LLINs (Long Lasting Insecticidal Nets) are the cornerstone for vector control, globally. However, their incessant use has resulted in widespread development of resistance in mosquito vectors, warranting continuous monitoring and investigation of the underlying mechanisms of resistance. Here, we identified a previously uncharacterized- Cub and Sushi Domain containing Insecticide Resistance (CSDIR) protein and generated evidence for its role in mediating insecticide resistance in the Anopheles stephensi.

ATEC23 Challenge: Automated prediction of treatment effectiveness in ovarian cancer using histopathological images.

Ovarian cancer, predominantly epithelial ovarian cancer (EOC), is a global health concern due to its high mortality rate. Despite the progress made during the last two decades in the surgery and chemotherapy of ovarian cancer, more than 70% of advanced patients are with recurrent cancer and disease. Bevacizumab is a humanized monoclonal antibody, which blocks VEGF signaling in cancer, inhibits angiogenesis and causes tumor shrinkage, and has been recently approved by the FDA as a monotherapy for advanced ovarian cancer in combination with chemotherapy.

Visible-Light-Mediated, Organophotocatalytic C-H Thiocyanation of Pyrazolo[1,5-]pyrimidines.

Herein, we report a metal-free, organophotoredox-catalyzed sustainable C-H thiocyanation of a biologically active class of N-heterocycles, pyrazolo[1,5-]pyrimidines, with potassium thiocyanate (KSCN) using 9-mesityl-10-methylacridinium perchlorate as the photocatalyst (PC) and molecular oxygen as the terminal oxidant under blue-light-emitting diode irradiation at room temperature. The developed catalytic protocol features mild reaction conditions, a broad substrate scope, a high yield of products, and a straightforward scalability. Mechanistic studies revealed a radical pathway involving reductive quenching of the PC by KSCN.

Challenging the Biginelli scaffold to surpass the first line antitubercular drugs: thymidine monophosphate kinase (TMPK) inhibition activity and molecular modelling studies.

New Biginelli adducts were rationalised, the introduction of selected anti-tubercular (TB) pharmacophores into the dihydropyrimidine (DHPM) ring of deoxythymidine monophosphate (dTMP), the natural substrate of thymidine monophosphate kinase (TMPK). Repurposing was one of the design rationale strategies for some selected mimics of the designed compounds. The anti-TB activity was screened against the M HRv strain where was superior to ethambutol (EMB), and was 9-fold more potent than pyrazinamide (PZA).

Adipocytes Promote Endometrial Cancer Progression Through Activation of the SIRT1-HMMR Signaling Axis.

Adipocyte is a predominant component of the omental adipose tissue that influences the tumor microenvironment and increases the risk of endometrial cancer progression (EC), however, little is known about the underlying mechanism. In this study, using a co-culture model, we found that the adipocyte-EC cell interaction promoted SIRT1 signaling in vitro and in vivo xenograft mice models. Furthermore, immunostaining of SIRT1 protein showed significantly higher expression of SIRT1 in endometrial cancer patients than in normal endometria.

Suspension Bead Loading (SBL): An Economical Protein Delivery Platform to Study URM1's Behavior in Live Cells.

Uniquely modified synthetic proteins are difficult to produce in large quantities, which could limit their use in various in vitro settings and in cellular studies. In this study, we developed a method named "suspension bead loading" (SBL), to deliver protein molecules into suspended living cells using glass beads, which significantly reduces the amount of protein required for effective delivery. We investigated the delivery efficiency of functionally different proteins and evaluated the cytotoxic effect of our method and the chemical and functional integrity of the delivered protein.

S100A12 inhibits Streptococcus pneumoniae and aids in wound healing of corneal epithelial cells both in vitro and in vivo.

Streptococcus pneumoniae, a leading cause of corneal infections worldwide, are extremely aggressive despite antibiotic sensitivity and exhibit increased resistance towards antibiotics. Antimicrobial peptides are often considered as potent alternatives against antibiotic resistance and here we have investigated the possible roles of S100A12, a host defense peptide, in wound healing and S. pneumoniae infection.

Surface energy and stress driven growth of extremely long and high-density ZnO nanowires using a thermal step-oxidation process.

Formation of highly crystalline zinc oxide (ZnO) nanowires with an extremely high aspect ratio (length = 60 μm, diameter = 50 nm) is routinely achieved by introducing an intermediate step-oxidation method during the thermal oxidation process of thin zinc (Zn) films. High-purity Zn was deposited onto clean glass substrates at room temperature using a vacuum-assisted thermal evaporation technique. Afterwards, the as-deposited Zn layers were thermally oxidized under a closed air ambient condition at different temperatures and durations.
