An alternative mitophagy pathway mediated by Rab9 protects the heart against ischemia
Energy stress, such as ischemia, induces mitochondrial damage and death in the heart. Degradation of damaged mitochondria by mitophagy is essential for the maintenance of healthy mitochondria and survival.

B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Alternative Excision Repair Pathways [PDF]
Alternative excision repair (AER) is a category of excision repair initiated by a single nick, made by an endonuclease, near the site of DNA damage, and followed by excision of the damaged DNA, repair synthesis, and ligation. The ultraviolet (UV) damage endonuclease in fungi and bacteria introduces a nick immediately 5' to various types of UV damage ...

To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

Aquaporin-10 Represents an Alternative Pathway for Glycerol Efflux from Human Adipocytes
Background Glycerol outflow from adipocytes has been considered for a decade to be mediated by aquaporin-7, an aquaglyceroporin highly expressed in the adipose tissue. Its involvement in glycerol metabolism has been widely studied also in humans.

Evolutionary interplay between viruses and R‐loops
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Is There an Alternative Pathway for Starch Synthesis? [PDF]
In leaf tissue, carbon enters starch via the gluconeogenesis pathway where d-glycerate 3-phosphate formed from CO(2) fixation is converted into hexose monophosphates within the chloroplast stroma. In starch-containing sink organs, evidence has been obtained indicating that the flow of carbon into starch follows a different pathway whereby hexose ...

Colorectal Adenocarcinoma with an Alternative Serrated Pathway [PDF]
In a 64-year-old woman, we identified a flat, elevated lesion that was located at the caecum and was composed of 3 different areas (areas A, B, and C). We diagnosed it as “carcinoma with sessile serrated adenoma/polyp (SSA/P)” histologically. Although area A was diagnosed as classical SSA/P, area B was regarded as a high-grade SSA/P.
